For the higher heights the distance from h1 to h2 was almost a meter which meant it was difficult to get eye level from h1 to h2 to accurately in a short amount of time. Is it a straight line? This is because the ball starts with more GPE. Materials 1. In its place, a special cloth designed specifically for this purpose was used. GPE=Mass (kg) Gravitational Field Strength (N/Kg) Height (m). The cookie is set by the GDPR Cookie Consent plugin and is used to store whether or not user has consented to the use of cookies. Concrete4. Working out the variation in results shows how accurate the experiment was. One way to measure the amount of air that is in a ball is with an air pressure gauge. Repeat steps 1-6 with the different balls. A cold ball will bounce farther than a warm one. A ball bounces in an arc, so measure the height at the top of the arc of the first bounce. Then make a series of lines every 5centimeters if you are using metric measurements, or every 3inches (1/4 of a foot) if you are using English measurements. Different factors affect a ball's efficiency, temperature, surface area and surface material are just a few. results, one of the many being that the harder the surface the ball was bouncing on, From the above table it can be seen that there were inaccuracies in the experiment. Carefully climb the ladder with the ball. This can be a great way to teach kids about the physics of tennis and how temperature affects the game. To determine how high a tennis ball will bounce when dropped from a . Does it slope up or down? energy a surface absorbs, the more of it will remain for a ball to bounce. Use the paint and a tape measure to make a series of lines on your roll of paper. Write each measurement in the data table. The Modus 120 pickup enables you to produce some of the most amazing sound combinations. The results of the experiment were obtained with a method that ensured that every drop was under similar conditions which ensured a fair test. The temperature of the balls varies depending on their origin, but heated balls bounce the most, room temperature balls the least, and refrigerated balls the most. The temperature of a tennis ball can affect its bounce height. troubles my partner and I had during our experiment along with the problems we For multiple bounces, it's just like dropping the ball again from a reduced height. This still took us time and we still couldn't catch the 70% is retained. chose balls and surfaces with different hardnesses, textures and compositions in catcher to catch the balls. The cookies is used to store the user consent for the cookies in the category "Necessary". Drag is a squared function of velocity and therefore as the ball drops drag increases a greater amount each second. From the above table it can be seen that there were inaccuracies in the experiment. Copyright 2023 StudeerSnel B.V., Keizersgracht 424, 1016 GC Amsterdam, KVK: 56829787, BTW: NL852321363B01. Also the ball flattening upon impact doesnt have to be taken into account whereas if one was measuring from the top of the ball as it hits the floor to the top of the ball before dropping it or at the top of its arc after bouncing or the middle of the ball as it hits the ground to the middle of the ball before dropping it or the middle of the ball at the top of its bounce then the fact that the ball flattens momentarily on impact with the floor would have to be taken into account. But how does concrete . Although catching small balls was an issue, we solved it by getting our better The colder, the lower the ball bounces, and vice versa. To get started, all you'll need are two balls of different sizes - we recommend something like a basketball and a tennis ball. the higher it popped up into the air. Here's what you need to do this experiment: Bouncy Balls - a least 6 identical balls; A measuring cup or mug for heating water in the microwave; Access to a freezer . This applies to a ball falling in a vacuum. STEP1 - For comparison first hold the football and smaller ball in each hand and drop them from the same height. It was difficult to get down to the exact level of the blue tack seeing as it meant lowering your entire upper body in the short amount of time taken for the ball to hit the floor and rebound again to get your eye level from h, (where the blue tack was stuck, approximately). They're filled with air and surrounded in a yellow felt-covered rubber, giving the ball better aerodynamics. hypothesis, we predicted that a rubber ball would bounce the highest on rough faced. Science Buddies: Pilobolus Spore Sac Launch. If we Above this point the height all balls will bounce to will not be directly proportional to the height they are dropped from, but the increase in the height they bounce to will increase more slowly in proportion to the height they are dropped from compared to the increase between lower heights before the ball shows signs of approaching its terminal velocity before it hits the ground. The strength of Nadals forehand is what makes him so good on clay. This results in faster . However, it was the basketball Find an outdoor wall where you can hang up your background, set up a ladder, and film your experiment. However, you may visit "Cookie Settings" to provide a controlled consent. Height will be the variable that we will vary. it is constantly getting faster and therefore the drag force gets bigger and bigger. is well-inflated and made of rubber which would give it more kinetic energy and Try your bounce test in different weather conditions. These two results were excluded when averages were being calculated and therefore the average variation between results used for calculating the average was even less than 3cm. Does height make a difference? Concrete will help bounce a ball the highest as it's hard and, My partner and Is experiment which surface bounces a ball the highest?, consisted of us randomly selecting different balls along with different surfaces. This did not happen in my experiment however. The Racquet Sports Industry's website states that, like human fingerprints, no two balls seem to be alike, and each has slightly different bouncing ability. Let the ball bounce until it stops, and then stop recording. The cookie is used to store the user consent for the cookies in the category "Performance". The height of the ball at each bounce is then calculated. I also Answer (1 of 4): The height to which a ball bounces depends on several factors: 1) The height from which it is dropped, 2) Whether it was thrown down or just dropped and how hard it was thrown, 3) How much energy is lost in the ball during the collision with the floor 4) How much energy is lost . Steel balls bounce higher than rubber balls. If the mass of the ball is heavier the weight is heavier (weight = mg) and downward force acting upon the ball is greater as well. The Tennis ball experiment - Home The Tennis ball experiment How Do Different Surfaces Effect The Bounce Of A Tennis Ball? Now use your data table to plot points on the graph. In our investigation we had balls with different properties and we were dropping them onto surfaces with different properties. The ball showed signs of reaching terminal velocity because the drag force began to approach the force gravity exerts upon the mass of the ball. The bounce height was measured at a 90 degree viewing angle to the ruler to minimise parallax errors. The equipment necessary to generate these conditions was not available and as a result the results obtained were not one hundred percent accurate. A glass ball will bounce higher than a rubber ball if it doesnt break. Abstract and Figures. Either the coefficient to restitution that was worked out is incorrect, which would mean that the first three results are inaccurate or subsequent results were inaccurate. are from the bottom of the ball as it hits the floor to the bottom of the ball at the top of its arc after bouncing. This would mean that one could re-examine the height to which it bounced to and find it exactly instead of having to make a split second judgement which is not half as accurate. it goes back into the ball, giving it more force to pop back up into the air. Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. This is impossible. Tennis balls bounce differently in the high altitude and at sea. If the elastic potential energy is the same then the same amount of energy is converted back into KE and so the balls leave the floor at the same speed. Do different kinds of balls bounce differently? According to the USTA regulations ball is tested for bounce by dropping it from a height of 100 inches (2.54 m) onto ; a bounce between 53 and 58 inches (1.3462 - 1.4732 m) is acceptable. However when the ball is dropped from a relatively low height, drag 0. The balls bounced higher on the concrete At 3ft, the basketball bounced 20 inches, the tennis ball bounced. by Jonah Lehrer on September 8, 2011. he official rule book of tennis is 35 pages long. To find out what affects the height to which a ball bounces. solid. Repeat step 5 with all of your other surfaces. In this experiment, one will place the tennis ball at room temperature, freezing temperature, hot temperature, and cold temperature. Each of the following experiments tests a different hypothesis. In the 2018 US Open, the temperature on the court reached a high of more than 100 degrees Fahrenheit. Why do marbles bounce so high? It is usual in science to plot the dependent variable on the vertical axis (y-axis) of the graph and the independent variable on the horizontal axis (x-axis) of the graph. A hard surface, such as concrete, absorbs less energy compared with a soft surface, such as a carpeted floor. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. - Measuring tape x Some balls to try are: soccer, basketball, volleyball, golf, tennis, or handball. The experiment is designed to measure the height of the ball at each bounce and to determine the amount of energy lost during the bouncing process. Keep releasing pressure and repeating the experiment until the ball no longer bounces. The acceleration due to gravity causes the ball to change direction and start moving downwards at stage 2. For any other use, please contact Science Buddies. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. Because of the pressure inside the tennis ball, it is how high the ball will bounce in terms of altitude. Then when dropping the ball again eye level was kept level with the blue tack. Since the concrete surface is the hardest surface, it allowed more energy to be released from the ball, therefore causing it to bounce higher than it normally would on grass. Do five drops on your first surface. = The distance between the bottom of the ball at the top of its arc after bouncing and the ground. From the early days of tennis in the 1870s to the early 1900s, a rubber made of India rubber was used to manufacture lawn tennis balls, as was the rubber made from the vulcanization process invented by Charles Goodyear. How does the material of a ball affect its bounce? As the height from which the ball was dropped from was increased, the GPE energy that the ball possessed before being dropped also increased. How Much Do Air Jordan Tennis Shoes Cost? Obviously, a ball won't bounce as high on carpet. We could have improved this You can compensate by adjusting your strings and striking a much bouncier tennis ball. Record the new pressure reading in your data table and repeat steps 4 and 5. Parallax error will be avoided by dropping the ball one time that will not be measured and placing a blob of blue tack onto the meter rule at the approximate height it bounced to. Use the pressure gauge to release some of the air pressure from the ball. Tennis balls are more likely to bounce on grass. Cross), Forecasting, Time Series, and Regression (Richard T. O'Connell; Anne B. Koehler), Give Me Liberty! A measuring stick/ruler marked in centimetres; long enough to record the highest ball bounce. It provided me with five repeats so that the maximum and minimum results could be discounted and a reliable average could be taken. , v is greater therefore KE is greater by a larger amount). From this it can be seen that using the average of the middle three results is more accurate than using the average of all five, as it automatically discounts most anomalies. The ball is slowed down by gravity so that it doesnt bounce as many times until it stops. Drag is a squared function of velocity and therefore as the ball drops drag increases a greater amount each second. h2= The distance between the bottom of the ball at the top of its arc after bouncing and the ground. Increased energy and movement results in a bounce. Since The surface onto which the ball is dropped upon will be kept the same. . The balls finish up with the same amount of energy and the only energy given out is thermal energy. The surface onto which the ball is dropped will affect the height to which the ball bounces because for any two objects that collide, the properties of both determine the percentage of the kinetic energy either possesses approaching the collision that is conserved subsequent to the collision taking place (Coefficient to restitution) discounting the effects of air resistance. - Paper x Decide on a height you want to drop the balls from . The material ball is made from will affect the ball as if it is smooth then the drag will be significantly less than if it is rough. Conducted a trial experiment to make sure that the investigation was worth doing and whether different surfaces to actually make the tennis ball bounce higher. We use cookies and those of third party providers to deliver the best possible web experience and to compile statistics. If the drag is less the ball will fall faster and is less likely to reach its terminal velocity. Hypothesis If I increase the height from which a ball is dropped then the bounce height will increase because it will increase the speed and create a larger impact causing the ball to bounce higher then dropping it from a lower height. Two different types of balls, Penn Championship and Non-Championship will be compared. Air resistance exists but does not affect the velocity of the ball significantly. Either the coefficient to restitution that was worked out is incorrect, which would mean that the first three results are inaccurate or subsequent results were inaccurate. This is a result of the Results are presented for a tennis ball, a . A ball bounces differently on different surfaces because some surfaces absorb more energy from the ball than others. Try comparing two days with different atmospheric pressure. Why Tennis Balls Bounce. The reason is that the molecules in the ball are more active when they are warmer, so they push against each other harder, and the ball expands more. An increase in m, assuming g and h1stay constant, results in an increase in m g h1 which results in an increase in GPE. As velocity increases air resistance increases in proportion to the square of the velocity. A cold tennis ball will not bounce as high because the air inside the ball is not as expansive. Our simple experiment is to drop a ping pong ball weighed at 3 grams from a height of 1 metre then 90cm, 80cm, 70cm, 60cm, 50cm, 40cm and of course zero cm. Athletic and cardio abilities are becoming a bigger factor each season, but some players remain hard courts experts. Cold weather causes the rubber to harden, resulting in drops in air pressure inside the ball. stay constant, results in an increase in m g h, stay constant, results in a decrease in m g h, The surface onto which the ball is dropped will affect the height to which the ball bounces because for any two objects that collide, the properties of both determine the percentage of the kinetic energy either possesses approaching the collision that is conserved subsequent to the collision taking place (Coefficient to restitution) discounting the effects of air resistance. Its not just a game for the wealthy; its also a game for everyone. As it did so the downward force was partially balanced out by the upwards force of drag, increasingly so the closer the ball got to its terminal velocity. Tennis balls are different at sea level and at high altitudes. Why does Rafael Nadal do so well on the clay? This will be a table tennis ball. bounces the highest on smooth concrete. This means that if a heavier ball is to be used then it will need to be dropped from higher to reach its terminal velocity. The higher the ball goes, the more GPE it ends up with. H is the height of the ball before it is dropped. The results are shorter rallies and quicker points. In air considerations have to be taken into account such as air resistance but even so the rough height to which it will bounce to can be predicted before dropping the ball. In this manner, you apply heat shrink to your head and heat it up until the shrink shrinks. 3. Make a line graph of your data. This was added onto another issue we had to For the lower heights the flight time of the ball was extremely short and again it was difficult to move ones head over the distance from h1 to h2 in order to obtain accurate results. The tennis balls bounce in different ways. Tennis cannot be played at a certain temperature; however, 70-90 degrees Fahrenheit is ideal. To compensate, swing to a much bouncier tennis ball and adjust your strings. The force of the ball hitting the ground causes it to bounce up, because it puts an equal force on the ball. This is longer than the 5-8 ms ball bounce from a solid surface or racquet. We then bounced the balls on the surfaces and A tennis ball is made of rubber and is covered with felt. As energy cannot be created or destroyed it follows that the energy must have come from the energy that the ball possesses. The higher the height from which the ball was dropped from, the higher the height to which it bounced. Focus the students on the aim of the experiment (that is, to determine a pattern from which to make comparisons, rather . These cookies track visitors across websites and collect information to provide customized ads. This is impossible. You will use an air pump, a basketball, and an air pressure gauge to test if changing the air pressure will change the bounciness of the ball. If the coefficient to restitution = 0.7, a ball dropping from h1in a vacuum would reach the height of 0.7 h1 after bouncing. Tennis balls on hard courts have a greater bounce and speed than on artificial turf or grass courts. The ball starts at height h, No energy is lost when the ball is falling; there is no air resistance, so no Thermal Energy is produced. However if two results are recorded that do not fit the trend of other results nor are close to results recorded for that height then the experiments accuracy would be brought into doubt. It shows that heights were recorded that exceeded the height that the ball would have reached had it been dropped in a vacuum. Once the drag force equals the gravitational force all forces are equal and acceleration stops. When it is dropped, the air molecules will squish together and then spring apart. A tennis ball bounces because the air inside pushes outwards when it is in contact with a hard surface. Some of the balls energy can be converted into heat. This would eliminate parallax error further. The ball did not reach terminal velocity however as it did not have enough time to accelerate to its terminal velocity. The longer it takes to stop, the higher it bounces to. Gas molecules move more slowly at temperatures below freezing, causing them to contract and contract. hard ball made of rubber should bounce the highest on a concrete surface, which This experiment requires a ball that will bounce and a meter stick or other measuring device. Air resistance exists but does not affect the velocity of the ball significantly. The same square of tiling will be used throughout the experiment so that inconsistencies between different floor tiles do not affect results. Does the weather make a difference? For a squash ball, f might be less than 0.5 or 0.25 - squash balls are not very bouncy. The ball has reached its terminal velocity and cannot fall any faster (unless dropped in a vacuum). We also use third-party cookies that help us analyze and understand how you use this website. Hypothesis: if different balls are bounced on different surfaces, then a rubber ball Concrete got bounced on the most, 5 times, and the highest, 55cm. This is due to two factors. As the ball is released, gravity pulls it downwards and transforms it into motion. This is because it is easiest as the figure read of the meter rule is the result. For a falling object the Coefficient to restitution (C, ) is equal to the velocity squared as the object is travelling at as it leaves the floor (v, ) divided by the velocity squared as it hits the floor (v, If a ball is dropped in a vacuum. The drag force increases as the ball goes faster. Line up the top of the table tennis ball with the top of the metre ruler (i.e. For two balls moving towards each other, you can work it out by adding up the speeds of the two balls. on different types of surfaces, then recorded the height of the bounce. Therefore the ball dropped from the higher height must give out more thermal energy in order to end up with the same amount of energy as the other ball. Warmer balls bounce better than cold ones. Science Buddies Staff. Why a ball bounces: The ball's energy is matched by the ground it hits. It relates to how much energy balls have, what they are made of, how they change shape and where the energy they have goes. Aim: to find out which surface bounces a ball the highest. However the conditions were kept the same for each drop of the ball. There is a chance that you will bounce. The reliability of our experiment wasn't so strong. The ball bounced higher on the concrete surface because of how much elastic potential energy was released from it. The Graph on page 23 shows that all of the results were very close together. Gather 15 to 20 tennis balls and a measuring tape. Experiment 2 is for testing the effect of air pressure. Will the air pressure change the bounciness of a ball? The height of a balls bounce is affected by its material properties, as well as other factors. Instead, as the ball is still always loosing GPE so long as it is still falling, all GPE is converted into thermal energy. Friday - 25/04/14 The ball gains energy of motion, known as kinetic energy. Use the measuring tape to measure 150 cm off the ground. ball bounced 6 inches. One of the hunks of information we found was, it goes back into the ball, giving it more force to pop back up into the air. As the ball falls to the surface it has kinetic energy. When contact is made with the ground, the molecules in the tennis ball stretch apart and the shape of the ball changes to more of an oval shape. This is because the experiment is a very short and simple one to carry out and if conducted efficiently can be completed easily within the time span allowed for collecting evidence. The ball did not appear to reach its terminal velocity which also supports my prediction. The temperature of a tennis ball greatly affects how high it bounces. For the most part, the document is a case study in compulsive precision. surface bounces a ball the highest. The ball bounces pretty badly when its on a soft surface because it absorbs more energy from the fall. Also the difference between the force of air resistance acting upon a ball travelling at 1ms, and the force of air resistance acting upon a ball travelling at 2ms, is far smaller than the difference between the force of air resistance acting upon a ball travelling at 20ms, and the force of air resistance acting upon a ball travelling at 21ms, , the faster the velocity that the ball reaches. small balls sometimes, but we could have improved this by taking many attempts = The distance between the bottom of the ball before it is dropped and the ground. Graph 1. Balls bounce in ways that are affected by gravity. When it hits the ground, the bottom of the ball becomes flat against the floor. So whether you're looking to learn more about the sport or just stay up-to-date on the latest news, we've got you covered. The harder the court surface is, the higher the rebounded ball will be. It would also be fun to explore the effect of different surfaces on the bounce of the bouncy ball. : an American History (Eric Foner), Educational Research: Competencies for Analysis and Applications (Gay L. R.; Mills Geoffrey E.; Airasian Peter W.), The Methodology of the Social Sciences (Max Weber), Biological Science (Freeman Scott; Quillin Kim; Allison Lizabeth), Campbell Biology (Jane B. Reece; Lisa A. Urry; Michael L. Cain; Steven A. Wasserman; Peter V. Minorsky), 4-3 Assignment Project Management Strategies. You also have the option to opt-out of these cookies. Bouncing Ball Investigation This is an experiment to investigate bouncing balls and how they behave in different situations. didn't catch the ball on time before it went back down to the ground, we would get The air trapped in the ball is forced into the ground when it hits the ground. During the preliminary experiment it was established that time was not an important factor that had to be taken into account when deciding how many different heights to drop the ball from and the interval between those heights. These inaccuracies could have been caused by external factors or parallax error even though efforts were made to avoid parallax error occurring - by dropping the ball one time that was not measured and placing a blob of blue tack onto the meter rule at the approximate height it bounced to. They are typically softer, allowing them to give them a little more space and make them easier to hit. The Cold Group (-15C) averaged 53.5 cm, the Cool Group (6C) averaged 98.5 cm, the Room Temperature Group (46C) averaged 114.5 cm, the Warm Group (100C) averaged 136.5 cm, and the Hot Group (142.5 cm) averaged 142.5 cm It was determined to be correct to my hypothesis. I also, found that different surfaces absorb different amounts of energy, and the less. A hard surface, like concrete or hardwood, hardly absorbs any, so most of the kinetic energy of the fall goes into bouncing the ball back up. Therefore the heavier the ball is, the faster its terminal velocity. - Pencil x As the temperature rises, the gas molecules in the tennis ball expand. Some of the kinetic energy of the ball is lost during the collision with the floor and the ball will not return to the original height. You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use. Kinetic energy and ball shape. This is because as the ball goes faster it passes through a greater volume of air each second. As the ball flattening upon impact with the floor is not visible as it happens so quickly it would be almost impossible to measure the size of the ball on impact with the floor. Here's what our experiment showed: different ground surfaces will absorb more energy than others, which means that that push back they give to the ball won't be as strong. The reason balls bounce is quite advanced science. Use the pressure gauge to release some of the air pressure from the ball. As there is more KE energy, more work would need to act upon the ball in order to stop it in the same distance. My partner and Is experiment which surface bounces a ball the highest? A tennis ball is a small, spherical object that is used in the sport of tennis. Why does a tennis ball bounce higher on concrete? Watch the video of the dropping tennis ball. This means that KE is the same for both balls when each ball hits the ground. harder surfaces will ultimately bounce a ball higher. As an example, on the day we performed our experiment, a strong wind was Keep a close eye on the ball, and instruct Phlebas to do the same. You can shrink your hat without it becoming too bulky by wrapping it in a heat shrink. The trip is going to be thoroughly enjoyable. By conducting our experiment, we learnt that well-inflated rubber balls bounce the Why Does One Tennis Shoe Pull Your Sock Down? Once the ball hits the ground, its displacement is momentarily zero. It was difficult to get down to the exact level of the blue tack seeing as it meant lowering your entire upper body in the short amount of time taken for the ball to hit the floor and rebound again to get your eye level from h1 to h2 (where the blue tack was stuck, approximately). Air pressure will affect the balls fall slightly as the concentration of air particles per cubic meter varies with air pressure. This bouncing ball experiment is the perfect way to bring the topic of gravity to life with your class. Each ball in a can is different in weight, diameter, and bounce. Write your measurements down. Not If you want to make the ball bounce lower, you can try cooling it down by putting it in the fridge or freezer for a few minutes. will start at 2m and then move down in intervals of 10cm to 10cm. Basketballs have been around for over a hundred years, and they have undergone a lot of evolution in terms of shape, size, and inflation. 2. (2020, January 12). All rights reserved.
