The bouncing of a tennis ball on a tennis court surface is analysed by making several simplifying assumptions about the physics of the interaction. This was when the ball was falling in air. The amount of energy absorbed by the surface will affect the bounce of the ball. Therefore the energy that the ball hits the floor with = mh, The proportion of energy lost when ball hits the floor = The Coefficient to the restitution of the two objects (C, All of the energy that the ball leaves the floor with is converted back into GPE, If dropping a ball in a vacuum all you need to know in order to know how high the ball will bounce to is h, can be found out by looking at a graph, the gradient, as a percentage of 1 gives the amount of energy conserved and therefore C. The clamp stand will be clamped down to the desk using a g-clamp to prevent it falling over and causing possible injuries. 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 . (Doherty, 1991). As they are pushed about, the molecules in the ball collide with and rub across each other." An average will then be taken. This cookie is set by GDPR Cookie Consent plugin. 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. Write each measurement in the data table. This is called the relative speed. As a result, they move at a slower rate of speed with less energy. 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. Keep releasing pressure and repeating the experiment until the ball no longer bounces. the "bouncing balls" experiment. Hypothesis: if different balls are bounced on different surfaces, then a rubber ball When a ball drops in air there is air resistance to which the ball loses energy in the form of thermal energy. 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 dependence of the speed or pace of the court on the coefficient of friction (COF) as well as the coefficient of restitution (COR) is derived. Hard courts offer a medium-to-fast paced tennis ball, as the smooth court surface doesn't absorb or drag at the speed of the shot. We then bounced the balls on the surfaces and - Sticky tape - 1 roll. This proves that the higher h1the more h2will differ from the height that the ball would have reached had it been dropped in a vacuum. How Much Do Air Jordan Tennis Shoes Cost? Height will be the variable that we will vary. The ultimate answer was that a basketball Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. The height of the ball at each bounce is then calculated. Therefore the ball goes higher. This would provide evidence on how the height from which the ball is dropped from affects the height to which it bounces without air resistance. GPE=Mass (kg) Gravitational Field Strength (N/Kg) Height (m). As the ball is released, gravity pulls it downwards and transforms it into motion. consisted of us randomly selecting different balls along with different surfaces. Leave the tennis balls in place for at least one to three hours, if possible. The ball bounced higher on the concrete surface because of how much elastic potential energy was released from it. Hypothesis. Apparatus:Clamp stand, meter rule 2, table tennis ball, desk. Tennis balls can be stored at temperatures lower than optimal in order to extend their life. Determine how high the ball rebounds on its first bounce. The balls finish up with the same amount of energy and the only energy given out is thermal energy. This is due to an inelasticity in the energy lost when the ball collides with the ground, as well as the fact that the ball bounces every time it is hit. Why do balls bounce higher on different surfaces? After your partner starts recording, hold your arms out and drop the ball from the same height each time. Why does a tennis ball bounce higher on concrete? If you're playing under 68 degrees, it's a good idea to make sure the ball doesn't bounce too much. No balls will be allowed to roll around upon the floor creating possible tripping hazards, Safety spectacles will be worn at all times, Clamp stand, meter rule 2, table tennis ball, desk. Use two people to measure the results; one person to drop the ball and one to measure the height to which it reaches after bouncing. B. This is why it h2will be 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. Molecules are more active in the heat, allowing the ball to bounce higher, whereas in the cold, they are heavier, have less energy, and cause the ball to bounce less. will differ from the height that the ball would have reached had it been dropped in a vacuum. Also it will affect its bouncing properties. h1and h2are 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. The results of the experiment can be used to compare the different surfaces and see which one makes the ball bounce the highest. H is the height of the ball before it is dropped. Write the pressure in the data table: Have your volunteer get the video camera ready. The maximum height will have to be less than two meters as that is the maximum height that the equipment allows. The equipment necessary to generate these conditions was not available and as a result the results obtained were not one hundred percent accurate. Its not just a game for the wealthy; its also a game for everyone. Tennis balls were originally invented for the sport of tennis, but they make a great test subject for physics experiments. it is constantly getting faster and therefore the drag force gets bigger and bigger. Then when dropping the ball again eye level will be kept level with the blue tack thus avoiding parallax errors. Keep releasing pressure and repeating the experiment until the ball no longer bounces. The Graph on page 23 shows that all of the results were very close together. Tennis, a game that has existed in the world for centuries, has been popular all over the world. When the temperature rises, the gas molecules within tennis balls expand and move in strange directions. Bouncing Ball Investigation This is an experiment to investigate bouncing balls and how they behave in different situations. We use cookies and those of third party providers to deliver the best possible web experience and to compile statistics. the concrete surface is the hardest surface, it allowed more energy to be released On the cardboard, mark the starting point, the point where the marble strikes the wood, and a point along the marble's path as it rolls away from the wood. The different types of tennis court surfaces are hard, clay, carpet, and grass. C. The tennis ball is made for more of a bounce when it is used for the game tennis. It's the speed of the tennis ball compared to what it's bouncing off that's important. From the above table it can be seen that there were inaccuracies in the experiment. For multiple bounces, it's just like dropping the ball again from a reduced height. 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. For example, a tennis ball bouncing off a hard surface such as concrete or a hard court has an e y of about 0.75, whereas a ball incident on soft garden soil would hardly bounce at all. h1 = The distance between the bottom of the ball before it is dropped and the ground. This would allow one to find the terminal velocity of the ball. - Rubber ball x Tennis balls with rough surfaces bounce higher than balls with smooth surfaces. The steel snaps back more quickly when it hits the ground. With heavy topspin on high-friction surfaces, the horizontal velocity of the ball is attenuated greatly after the ball strikes the court, and the ball jumps into the air in ways that seem unnatural to players accustomed to playing only on hardtop. Air resistance exists but does not affect the velocity of the ball significantly. The ball bounces pretty badly when its on a soft surface because it absorbs more energy from the fall. This means that the higher h. will differ from the height that the ball would have reached had it been dropped in a vacuum. This will be repeated five times, possibly more (for accuracy), for each height and the top and bottom results will be discounted. Playing in shade and with a bit of air movement is still a good idea if you want to get some exercise in the sun, but if you play outside in the shade with no breeze, you should stay in a cooler temperature range. This will be called the average of the middle three repeats. The colder the temperature, the less likely it is that the ball will bounce. Now use your data table to plot points on the graph. Each can from the same manufacturer can be different. Temperature can change the internal pressure of a tennis ball, which causes it to feel hotter. The pressure on the ball is created by the air pushing against it. 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. by Jonah Lehrer on September 8, 2011. he official rule book of tennis is 35 pages long. These cookies ensure basic functionalities and security features of the website, anonymously. The more KE the ball leaves the floor with the longer it takes to stop due to the force of gravity and return back to the floor again. Make a note of which one bounces up higher and how high they bounce! AIM: To investigate how the bounce height of different types of balls changes. This applies to a ball falling in a vacuum. Conclusion: As the ball falls to the surface it has kinetic energy. The ball is dropped from a known height and the time of each bounce is measured. small balls sometimes, but we could have improved this by taking many attempts being able to catch the ball on time was another one of the issues we faced. - Paper x What do you think this means about your results? We then bounced the balls on the surfaces and, measured the heights. This cookie is set by GDPR Cookie Consent plugin. was blowing in, so that if the balls were blown away, they would come straight to As velocity increases air resistance increases in proportion to the square of the velocity. Balls bounce in ways that are affected by gravity. Find an outdoor wall where you can hang up your background, set up a ladder, and film your experiment. All rights reserved. The more particles per cubic meter, the more drag acting upon the ball. To find out what affects the height to which a ball bounces. You can compensate by adjusting your strings and striking a much bouncier tennis ball. EQUIPMENT: 1 metre ruler 1 table tennis ball. The reliability of our experiment wasn't so strong. Taking an average of several results creates a measurement in the middle of the variation created by the experiment, which is the result that is closest to the height that would be recorded for the balls bounce if it were measured in an experiment that was totally accurate. changing air density, temperature. There is a chance that you will bounce. Therefore any change to the height from which the ball starts with affects the height to which it bounces to. Steel balls bounce higher than rubber balls. When the ball hits the floor and stops, that energy has to go somewhere. 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. This would eliminate parallax error further. The reason balls bounce is quite advanced science. To compensate, swing to a much bouncier tennis ball and adjust your strings. The cookie is used to store the user consent for the cookies in the category "Other. But what makes a ball bounce? an incorrect and unreliable result. Once the drag force equals the gravitational force all forces are equal and acceleration stops. As the temperature rises, the gas molecules in the tennis ball expand. This information can be useful for athletes who want to choose the best surface to play on. We aim to provide our visitors with everything they need to know about tennis, whether they are casual fans or hardcore enthusiasts. If the coefficient to restitution = 0.7, a ball dropping from h, in a vacuum would reach the height of 0.7 h, As velocity increases air resistance increases in proportion to the square of the velocity. The trip is going to be thoroughly enjoyable. For the lowest three points air resistance is approximately equal to zero due to the ball having a low velocity, as it was dropped from a low height, and therefore hits less air particles per second than a ball traveling at a faster speed. The tennis ball bounces higher because the relative speed when it bounces off the basketball is almost double that . For any other use, please contact Science Buddies. solid. Which surface bounces a ball the highest? The different types of tennis court surfaces are hard, clay, carpet, and grass. 1 tennis ball 1 golf ball. The energy that the ball hits the floor with is kinetic energy. : 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. Discussion: The mass of the ball will affect the height the ball bounces to because it affects the balls starting energy. This means it will be travelling the same speed when it hits the ground. It therefore hits more air particles each second and so the force of drag is bigger the faster the ball goes. Focus. This did not happen in my experiment however. The experiment was conducted well however as the utmost efforts were brought into place to avoid parallax error and it was ensured as far as possible that factors that affected how high the ball bounced, excluding the height, were kept constant throughout the experiment. External factors, i.e. It will be vinyl tiling. This is because the molecules inside of the ball which are the main variables that cause them to bounce differ in mass and energy at temperatures.

Answer (1 of 2): Some surfaces absorb more energy than others do. Balls change shape during play. We did this by bouncing different types of balls or carpet. The tennis balls bounce in different ways. The combination of the material properties of a ball (surface textures, actual materials, amount of air, hardness/ softness, and so on) affects the height of its bounce. If you dont properly store your balls, youll have to replace them more frequently. Calculating the coefficient to restitution of ball hitting the floor: The coefficient to restitution can be found out from a graph of h1against h2. 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. The coefficient to restitution can be found out from a graph of, it follows the gradient of the graph change in h. . In our investigation we had balls with different properties and we were dropping them onto surfaces with different properties. This is because it is easiest as the figure read of the meter rule is the result. Most of the points on grass are very short. rubber ball would bounce the highest on concrete. The surface onto which the ball is dropped upon will be kept the same. One way to do this is to put the ball in a bowl of hot water for a few minutes. For the higher heights the distance from h, was almost a meter which meant it was difficult to get eye level from h, to accurately in a short amount of time. There were some trends observed in our Harder balls have a higher recovery rate than softer ones, and clay-based balls have a higher recovery rate than rubber or synthetic balls. Use the measuring tape to measure 150 cm off the ground. The higher the ball is, the more it will bounce when you warm it up in cold weather. As the ball hits the floor with less KE than it would have done if it had been dropped in a vacuum it follows that less energy is converted into elastic potential energy and back into KE again. A ball that is dropped in air however is subjected to air resistance which affects the height to which it bounces. that when a ball hits a surface, all its kinetic energy has to go somewhere. Carefully climb the ladder with the ball. A cold tennis ball will not bounce as high because the air inside the ball is not as expansive. However the conditions were kept the same for each drop of the ball. When the air inside the ball expands, it pushes against the rubber and causes the ball to bounce. As a result, the balls bounce decreases as pressure decreases. Which surface bounces a ball the highest? Method:The apparatus will be set up as shown: H is the height of the ball before it is dropped. Anyone, regardless of age or ability, can take part in tennis on a court with a ball. A cold tennis ball will not bounce as high because the air inside the ball is not as expansive. troubles my partner and I had during our experiment along with the problems we It will not bounce to high if it is heavy. To a wider range of results i.e. Overall, our experiment taught us that harder When the ball was dropped from the higher heights the ball began to show signs of reaching its terminal velocity before it reaches the ground. The acceleration due to gravity causes the ball to change direction and start moving downwards at stage 2. present. use four meter sticks and go right the way up to four meters. Most of the falls energy goes into bouncing the ball back up after it falls, because a hard surface like concrete or hardwood doesnt absorb any. KE = 1/2mv where m = mass and v = velocity, 1/2mv = mhg - thermal energy (lost as a result of drag). The cookie is used to store the user consent for the cookies in the category "Performance". Hot balls were the more likely to bounce higher than cold balls. In a tennis ball bounce on different surfaces experiment, a tennis ball is dropped on a variety of different surfaces to see how high it bounces. Our team of volunteer scientists can help. measured the heights. This experiment requires a ball that will bounce and a meter stick or other measuring device. Drop (do not throw) the ball from a carefully measured height using the meter stick. High bounce ball 2. This would allow the actual coefficient to restitution to be calculated. Explanation: When all three balls are dropped from the same height, the rubber ball will bounce the highest because it has the greatest elasticity. This therefore provides accurate and reliable results. This is because as the ball goes faster it passes through a greater volume of air each second. his the height of the balls bounce. A tennis ball is made of rubber and is covered with felt. 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. The more energy that the ball possessed before being dropped, the more energy was converted into KE while the ball fell. A cold ball typically has less bounce than a warm ball. Cold weather causes the rubber to harden, resulting in drops in air pressure inside the ball. The higher the height from which the ball was dropped from, the higher the height to which it bounced. Fully pump up the basketball and check the pressure with the pressure gauge. 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. surface bounces a ball the highest. Increased energy and movement results in a 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. Aim: to find out which surface bounces a ball the highest. Tiles3. If you were to see a ball drop to the ground in slow motion, you would see its shape change dramatically. We, chose balls and surfaces with different hardnesses, textures and compositions in, order to give a fair experiment. Grades: Preschool and K-2. As the height from which the ball was dropped from was increased, the GPE energy that the ball possessed before being dropped also increased. Different courts are better suited to each players style. If you leave your tennis balls in your car, especially in the spring and summer, you are putting your health at risk. Belowis the graph of h1against h2. us. Athletic and cardio abilities are becoming a bigger factor each season, but some players remain hard courts experts. 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. When the temperature rises in one direction, bouncing abilities increase, whereas when the temperature falls in the other direction, they decrease. When it hits the ground, the bottom of the ball becomes flat against the floor. If you like this project, you might enjoy exploring these related careers: You can find this page online at: https://www.sciencebuddies.org/science-fair-projects/project-ideas/Phys_p039/physics/balls-bouncing-off-of-surfaces. The experiment was conducted as the method (below) states. If it bounces up less than .5 meter, then it is more inelastic. 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. Improvements that could be made to the experiment if future work was to be done: To provide additional relevant evidence I would conduct further work as follows; I would like to conduct the same experiment in a vacuum. To be consistent, again measure to the bottom of the ball. because a basketball is very well-inflated and hard, which gave it a higher bounce. Science Buddies Staff. For a squash ball, f might be less than 0.5 or 0.25 - squash balls are not very bouncy. Do you have specific questions about your science project? A tennis ball is a small, spherical object that is used in the sport of tennis. . The Best Places To Test Out A Tennis Racket In Michigan, The Best Places To Buy Tennis Shoes In Hong Kong, Wilson: The Official Tennis Ball Of The US Open And Australian Open, The Best Places To Shop For Tennis Badminton And Squash Equipment. Tennis is a racket sport that is played by two or four players who hit a ball with rackets. Reverse Engineering: Ball Bounce Experiment Hands-on Activity Reverse Engineering: Ball Bounce Experiment (2 Ratings) Click here to rate Quick Look Partial design process Grade Level: 4 (3 - 5) Time Required: 1 hours 45 minutes (2 or 3 class periods) Group Size: 3 Subject Areas: Students investigate balls and their bounce copyright Summary Drag is a squared function of velocity and therefore as the ball drops drag increases a greater amount each second. Working out the variation in results shows how accurate the experiment was. The children were oblivious to these . Take a ball and place it on the 150 cm line and drop it. It should be on a smooth cement surface for optimal ball bouncing. 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). But opting out of some of these cookies may affect your browsing experience. Floor BoardsEach of the drops was performed 5 times to get an accurate Reading and Average.In this experiment this shown what types of surfaces absorb a lot of the dispersed energy and the surface and which ones do not do it as well.This was done on iMovie and took 2 Hours to Create.So Please Enjoy! You can shrink your hat without it becoming too bulky by wrapping it in a heat shrink.
