Although we had all these challenges, energy a surface absorbs, the more of it will remain for a ball to bounce. When it is dropped, the air molecules will squish together and then spring apart. Each ball in a can is different in weight, diameter, and bounce. Analytical cookies are used to understand how visitors interact with the website. Determine how high the ball rebounds on its first bounce. Why a ball bounces: The ball's energy is matched by the ground it hits. This is called the relative speed. Take a ball and place it on the 150 cm line and drop it. This will be repeated five times, possibly more (for accuracy), for each height and the top and bottom results will be discounted. The ball shoots up with less energy because of this. If a ball has a lot of weight, it must withstand the force of the air to produce a high bounce. concrete, in which we were incorrect. concur, which was catching the small balls. Use the pencil and ruler to connect the incoming and outgoing trajectories of the marble to the point where the marble bounced off the wood. 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. We then bounced the balls on the surfaces and, measured the heights. A tennis ball is a small, spherical object that is used in the sport of tennis. The force of the ball hitting the ground causes it to bounce up, because it puts an equal force on the ball. These cookies ensure basic functionalities and security features of the website, anonymously. According to our background research, a 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. The more KE that the ball possessed as it hit the floor, the more that was transferred into elastic potential energy and back into KE. Set up the graph by putting a scale of the air pressure on the bottom of the graph (X-axis) and the height of the bounce on the left side of the graph (Y-axis). (2020, January 12). less air resistance. Calculating the coefficient to restitution of ball hitting the floor: The coefficient to restitution can be found out from a graph of h1against h2. You can even play tennis outside in any weather. As there is more KE, more energy is converted into elastic potential energy, As there is more elastic potential energy, more energy is converted back into KE energy. Which ball will bounce higher off a hard surface? The colder, the lower the ball bounces, and vice versa. How can you measure the height a ball bounces? The higher the air pressure the more air particles per cubic meter. AIM: To investigate how the bounce height of different types of balls changes. Use the pressure gauge to release some of the air pressure from the ball. h2= The distance between the bottom of the ball at the top of its arc after bouncing and the ground. . 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. As the ball falls it hits against air particles. 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. This is because as the ball goes faster it passes through a greater volume of air each second. It would also be fun to explore the effect of different surfaces on the bounce of the bouncy ball. Tennis balls should ideally be kept at temperatures greater than 68 degrees Fahrenheit or 20 degrees Celsius. Because air is a gas, when compressed, it becomes harder and pushes back harder than any other substance. 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. troubles my partner and I had during our experiment along with the problems we This also proves the accuracy of the experiment. Use the measuring tape to measure 150 cm off the ground. Some balls to try are: soccer, basketball, volleyball, golf, tennis, or handball. Decide on a height you want to drop the balls from . I will drop the ball 3 If you play in hot weather, your balls may bounce significantly more. It should be tall enough to hang up behind your ladder, about 5feet tall. For a squash ball, f might be less than 0.5 or 0.25 - squash balls are not very bouncy. A hard surface, such as concrete, absorbs less energy compared with a soft surface, such as a carpeted floor. 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 drop weight then bounces off the ball with 68-77 percent of its incident speed (46-59% of its incident energy). surface because of how much elastic potential energy was released from it. To be consistent, again measure to the bottom of the ball. 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. Also the facts that there were no anomalies and that all of the points were very close to the line of best fit show that the experiment was relatively accurate. The pressure on the ball is created by the air pushing against it. From this I am able to determine that the experiment was very accurate. bounces the highest on smooth concrete. Use the pressure gauge to release some of the air pressure from the ball. The balls bounced higher on the concrete An average will then be taken. Keep a close eye on the ball, and instruct Phlebas to do the same. Doherty, P., 1991. Aim:To find out what affects the height to which a ball bounces. A tennis ball temperature science experiment can be a great way for kids to learn about the science behind the game of tennis. The balls dropped from 75 centimeters will bounce higher than those dropped from 50 centimeters, and the balls in the 50 centimeter trials will bounce higher than those in the 25 centimeter trials. Once the drag force equals the gravitational force all forces are equal and acceleration stops. Warmer balls bounce better than cold ones. 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. The tennis ball was then dropped from various heights; 1, 1.5 and 2 meters above a hard surface, using a meter ruler, before it was dropped onto the ground and the resulting bounce height measured. A decrease in h1, assuming g and m stay constant, results in a decrease in m g h1which results in a decrease in GPE. Bouncing is what makes playing with a ball so much fun. This would allow one to find the terminal velocity of the ball. 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. Also it shows inaccuracies in the experiment as it shows that heights were recorded that exceeded the height that the ball would have reached had it been dropped in a vacuum. Why do balls bounce higher on different surfaces? Balls are not round. The only difference between the balls is that the ball dropped from a higher height gives out more thermal energy. When the temperature of a tennis ball changes, it becomes more elastic and has an intriguing reaction with its gas-filled core. h1 = The distance between the bottom of the ball before it is dropped and the ground. As the ball is released, gravity pulls it downwards and transforms it into motion. 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 Experiment Click the following buttons to skip to a page. Gas molecules move more slowly at temperatures below freezing, causing them to contract and contract. EQUIPMENT: 1 metre ruler 1 table tennis ball. Balls change shape during play. This was when the ball was falling in air. 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. Answer (1 of 2): Some surfaces absorb more energy than others do. Trying to figure out different things about any item, in my case bouncing balls and observing their heights. 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. Method: 1. 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). In my science fair experiment, the golf ball overall was the ball that bounced the highest. Balls bounce in ways that are affected by gravity. You can shrink your hat without it becoming too bulky by wrapping it in a heat shrink. 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 . (Image by Harold E. "Doc" Edgerton), http://www.exploratorium.edu/sports/ball_bounces/index.html, http://www.exploratorium.edu/baseball/bouncing_balls.html, Playing the Angles: The Physics of Balls Bouncing Off of Surfaces. Let the ball bounce until it stops, and then stop recording. Warm up the ball before it is used to increase its bounce. Some of the balls energy can be converted into heat. We also use third-party cookies that help us analyze and understand how you use this website. Then when dropping the ball again eye level will be kept level with the blue tack thus avoiding parallax errors. This is correct unless the ball shows signs of reaching terminal velocity. is well-inflated and made of rubber which would give it more kinetic energy and Gravel got bounced on the least, 1 time . Why does Rafael Nadal do so well on the clay? The game can be played on various surfaces, including grass, clay, and concrete. You can also try using a hair dryer to heat the ball up. Let the ball bounce until it stops, and then stop recording. For any other use, please contact Science Buddies. 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. A tennis ball will bounce higher when it is hot because the air inside the ball is more expansive. The higher h1, the faster the velocity that the ball reaches. from the ball, therefore causing it to bounce higher than it normally would on dirt If you dont properly store your balls, youll have to replace them more frequently. Most experiments investigate the effect of an independent variable on a dependent variable. Explanation: When all three balls are dropped from the same height, the rubber ball will bounce the highest because it has the greatest elasticity. Obviously, a ball won't bounce as high on carpet. The tennis balls bounce in different ways. The harder the court surface is, the higher the rebounded ball will be. We use cookies and those of third party providers to deliver the best possible web experience and to compile statistics. 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. The same surface can be used to play both doubles and singles matches. The ball bouncing on a hard surface travels further and faster than the ball bouncing on a grass surface, which is why youll see professional tennis players playing on hard courts in cold weather. A tennis balls trajectory is determined by its temperature. The ball did not appear to reach its terminal velocity which also supports my prediction. The acceleration due to gravity causes the ball to change direction and start moving downwards at stage 2. Ball trial 1 trail 2 trial 3 average When the ball deforms, its molecules are stretched apart in some places and squeezed together in others. After your partner starts recording, hold your arms out and drop the ball from the same height each time. (2020, November 20). 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. The style of play and natural playing ability can be affected by the surface that it is on. As a result, they move at a slower rate of speed with less energy. I used a Flexible measuring tape to measure what the height was. Changes in the area of linoleum floor tile that the ball collided with may have affected the height to which it bounced to thus producing variation between results. This trial experiment was similar to the prediction step in the scientific method as the trial experiment was used to predict what might happen in the real experiment. Few independent variables will be changed, so the investigation is easy to manage, and the data is easier to process. Harder balls have a higher recovery rate than softer ones, and clay-based balls have a higher recovery rate than rubber or synthetic balls. It is important to let the ball fall out of your hands, and not to push it down with your hands, wrists, or arms. Science Buddies Staff. During the research fraction of the experiment, it was The same square of tiling will be used throughout the experiment so that inconsistencies between different floor tiles do not affect results. For a falling object the Coefficient to restitution (CR) is equal to the velocity squared as the object is travelling at as it leaves the floor (v22) divided by the velocity squared as it hits the floor (v12): If dropping a ball in a vacuum all you need to know in order to know how high the ball will bounce to is h1 and CR. These cookies track visitors across websites and collect information to provide customized ads. Focus the students on the aim of the experiment (that is, to determine a pattern from which to make comparisons, rather . The energy that the ball hits the floor with is kinetic energy. Measure from the bottom of the ball. This means that the faster that the ball travels the larger the force of air resistance upon it. The air in the ball expands and contracts as it is compressed. 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. energy a surface absorbs, the more of it will remain for a ball to bounce. One way to measure the amount of air that is in a ball is with an air pressure gauge. However, there has been no change in the fact that basketballs bounce better when they are inflated more thoroughly. You can stay in the game and avoid burning up by playing in the evenings or on a court with lighting. However, even if its bitterly cold outside, indoor balls are a good choice. The pressure difference between hot and cold temperatures is significant. Balls bounce differently on different axes. Overall, our experiment taught us that harder The data from the experiment shows that the weight of the ball is important when bouncing. to find out which surface bounces a ball the highest. [accessed August 4, 2006]. This still took us time and we still couldn't catch the - Ping pong ball x C. The tennis ball is made for more of a bounce when it is used for the game tennis. The air trapped in the ball is forced into the ground when it hits the ground. This applies to a ball falling in a vacuum. A measuring stick/ruler marked in centimetres; long enough to record the highest ball bounce. Why do balls bounce higher on different surfaces? 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 . One way to do this is to put the ball in a bowl of hot water for a few minutes. This is impossible. This website uses cookies to improve your experience while you navigate through the website. Why does a tennis ball bounce higher on concrete? 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. Why Tennis Balls Bounce. Also it shows inaccuracies in the experiment as it shows that heights were recorded that exceeded the height that the ball would have reached had it been dropped in a vacuum. Now use your data table to plot points on the graph. This is because it is the easiest and quickest variable to alter. One of the hunks of information we found was Different factors affect a ball's efficiency, temperature, surface area and surface material are just a few. A decrease in bounce is caused by a colder temperature. CR can be found out by looking at a graph, the gradient, as a percentage of 1 gives the amount of energy conserved and therefore CRcan be found without knowing v22or v12. 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. Hard court tennis demands a lot from your joints! This is because the ball starts with more GPE. Fully pump up the basketball and check the pressure with the pressure gauge. = The distance between the bottom of the ball at the top of its arc after bouncing and the ground. Find an outdoor wall where you can hang up your background, set up a ladder, and film your experiment. As energy cannot be created or destroyed it follows that the energy must have come from the energy that the ball possesses. 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. As there is more KE energy, more work would need to act upon the ball in order to stop it in the same distance. Then when dropping the ball again eye level was kept level with the blue tack. Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. Watch the video of the dropping tennis ball. Therefore the heavier the ball is, the faster its terminal velocity. Therefore, In competitive tennis, sweat loss can quickly exceed the normal body temperature, causing electrolyte and body water deficits, as well as thermal stress that can significantly alter a players physiology, perception of effort, and ability to perform well on court. B. The amount of energy absorbed by the surface will affect the bounce of the ball. - Measuring tape x 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). Different courts are better suited to each players style. The ball has reached its terminal velocity and cannot fall any faster (unless dropped in a vacuum). All rights reserved. If a ball reaches terminal velocity at 20cm from the floor when dropped from 2m, it will reach terminal velocity at 10cm from the floor when dropped from 1.9m. This cookie is set by GDPR Cookie Consent plugin. Does height make a difference? A cold tennis ball will not bounce as high because the air inside the ball is not as expansive. This means that KE is the same for both balls when each ball hits the ground. The steel has a lot of bounce power due to its better storage of energy. We Place the video camera on a level that will be able to clearly record the experiment, whilst a person sits beside the tape measurer 4. 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. As an example, on the day we performed our experiment, a strong wind was Anyone, regardless of age or ability, can take part in tennis on a court with a ball. Prediction reasons for variable control: The height the ball is dropped from will affect the height the ball bounces to due to the energy chain the ball goes through as it is dropped and bounces up again. As a result, the ball is lifted in this manner. Line up the top of the table tennis ball with the top of the metre ruler (i.e. As for catching the balls on time, we changed our hand positioning and The Tennis ball experiment - Home The Tennis ball experiment How Do Different Surfaces Effect The Bounce Of A Tennis Ball? Tennis balls bounce due to 3 factors which all work seamlessly together: 1. didn't catch the ball on time before it went back down to the ground, we would get Do different kinds of balls bounce differently? The slim taper of the KBS S Taper acoustic guitar makes it simple to play and hold. Therefore any change to the weight of the ball will affect the energy the ball has initially, which, as previously stated, affects the height to which the ball bounces. Hot balls were the more likely to bounce higher than cold balls. 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. Introduction: On a grass tennis court, e y varies from about 0.6 to 0.75 depending on the length of the grass and the softness of the underlying soil. Necessary cookies are absolutely essential for the website to function properly. Performance cookies are used to understand and analyze the key performance indexes of the website which helps in delivering a better user experience for the visitors. When dropped on a solid surface, not even a super ball bounces back as high as its initial height, but some balls do bounce a lot better than others. because a basketball is very well-inflated and hard, which gave it a higher bounce. Science Buddies: Pilobolus Spore Sac Launch. Try bouncing different kinds of balls to test this question. But what makes a ball bounce? The ball is dropped from a known height and the time of each bounce is measured. "Balls Bouncing Off of Surfaces.". Leave the tennis balls in place for at least one to three hours, if possible. What affects ball bounce? What do you think this means about your results? us. The decision for the size of interval and the amount of results collected will depend upon the time taken to conduct the experiment and any other factors that may become apparent during the preliminary experiment. Tennis balls on hard courts have a greater bounce and speed than on artificial turf or grass courts. 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. Our team of volunteer scientists can help. When printing this document, you may NOT modify it in any way. Grades: Preschool and K-2. The weight and material of the ball will be kept the same throughout the experiment by using the same ball. Also it will affect its bouncing properties. Working out the variation in results shows how accurate the experiment was. Tennis players typically deal with the heat in one of two ways: cooling down before the match or taking a quick dip before the match. This is because it is easiest as the figure read of the meter rule is the result. discovered that there is a handful of information that would assist my partner and I 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. Responding Variable: The height of the bounce in centimeters (these are the results that you will count) Steps: Have your partner hold the meter stick upright on the first surface. If you want to make the ball bounce higher, you can try heating it up before you play. - Basketball x small balls sometimes, but we could have improved this by taking many attempts In modern tennis, the differences and subtleties of each surface tend to disappear. The balls finish up with the same amount of energy and the only energy given out is thermal energy. We use cookies and those of third party providers to deliver the best possible web experience and to compile statistics. 15 inches, and the golf ball bounced 26 inches. It provided me with five repeats so that the maximum and minimum results could be discounted and a reliable average could be taken. 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.
