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. 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. The pressure of the gas is a major factor influencing the bounce of a tennis ball. surface bounces a ball the highest. A cold ball will bounce farther than a warm one. Acrylic-topped, this surface offers the most consistent ball bounce of all the outdoor tennis courts. A tennis ball is made of rubber and is covered with felt. 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. The ball moves upwards, reaching stage 1, i.e., maximum height, and its velocity is momentarily zero. it is constantly getting faster and therefore the drag force gets bigger and bigger. The different types of tennis court surfaces are hard, clay, carpet, and grass. - Rubber ball x These cookies track visitors across websites and collect information to provide customized ads. 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. 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. The strength of Nadals forehand is what makes him so good on clay. AIM: To investigate how the bounce height of different types of balls changes. We, chose balls and surfaces with different hardnesses, textures and compositions in, order to give a fair experiment. As a result, they move at a slower rate of speed with less energy. For any other use, please contact Science Buddies. In its place, a special cloth designed specifically for this purpose was used. . (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. h1will start at 2m and then move down in intervals of 10cm to 10cm. Different courts are better suited to each players style. The ball did not reach terminal velocity however as it did not have enough time to accelerate to its terminal velocity. Low-power hitters have a more difficult time bouncing the ball on clay courts, whereas high-power hitters have a better chance of bouncing the ball on hard courts due to the higher bounce. This means for the ball to reach terminal velocity the drag force has to be bigger and for the drag force to be bigger the ball has to fall faster (so that more air particles hit the ball every second). Make a note of which one bounces up higher and how high they bounce! Keep a close eye on the ball, and instruct Phlebas to do the same. The cookie is used to store the user consent for the cookies in the category "Other. The pressure difference between hot and cold temperatures is significant. [accessed August 4, 2006]. 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. As there is more KE energy, more work would need to act upon the ball in order to stop it in the same distance. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. Then when dropping the ball again eye level will be kept level with the blue tack thus avoiding parallax errors. A lot of This is correct unless the ball shows signs of reaching terminal velocity. As velocity increases air resistance increases in proportion to the square of the velocity. to find out which surface bounces a ball the highest. 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. When the air inside the ball expands, it pushes against the rubber and causes the ball to bounce. 1 tennis ball 1 golf ball. When the ball deforms, its molecules are stretched apart in some places and squeezed together in others. Now, take your video and watch it to gather your data. The air in the ball expands and contracts as it is compressed. Also it will affect its bouncing properties. Answer (1 of 2): Some surfaces absorb more energy than others do. This also proves the accuracy of the experiment. 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. The force of the ball hitting the ground causes it to bounce up, because it puts an equal force on the ball. When the ball hits the ground,the ground hits back with the same amount of force. Balls are not round. All of the factors that could have affected the results that were uncontrollable could have produced variations between results. 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. chose balls and surfaces with different hardnesses, textures and compositions in Once the drag force equals the gravitational force all forces are equal and acceleration stops. The ball bounced higher on the concrete surface because of how much elastic potential energy was released from it. Grades: Preschool and K-2. - Four surfaces (carpet, rough concrete, dirt and smooth concrete). Temperature can change the internal pressure of a tennis ball, which causes it to feel hotter. Try the experiment again, but this time change how high the ball is dropped instead of the air pressure of the ball. When it hits the ground, the bottom of the ball becomes flat against the floor. Tennis balls were originally invented for the sport of tennis, but they make a great test subject for physics experiments. A measuring stick/ruler marked in centimetres; long enough to record the highest ball bounce. For instance result 3 from 200cm was an anomaly but was not taken into account when taking the average of the middle three. Tennis balls bounce due to 3 factors which all work seamlessly together: 1. 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. This applies to a ball falling in a vacuum. Warm up the ball before it is used to increase its bounce. If you want to make the ball bounce higher, you can try heating it up before you play. Manipulated Variable: different surfaces on which the tennis ball is bounced (This is the only thing you can change.) Concrete4. Apparatus:Clamp stand, meter rule 2, table tennis ball, desk. 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. - Pencil x I think this is What do you think this means about your results? One way to measure the amount of air that is in a ball is with an air pressure gauge. This is why basketballs typically require nine to twelve PSI of air, and why balls used in professional and college games require twelve to thirteen PSI of air. This would eliminate parallax error further. Watch the video of the dropping tennis ball. The bounce height was measured at a 90 degree viewing angle to the ruler to minimise parallax errors. As the ball falls it hits against air particles. 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. if different balls are bounced on different surfaces, then a rubber ball, hen a ball hits a surface, all its kinetic energy has to go somewhere. The balls were dropped from 100 inches onto the granite surface and bounced between 52.93 and 58.43 inches. 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. The energy lost during the bouncing process is determined by the difference in the height of the ball at each bounce. Tennis cannot be played at a certain temperature; however, 70-90 degrees Fahrenheit is ideal. Take your class outside, to an area with a smooth, flat surface. Tennis balls are more likely to bounce on grass. What factors affect the bounce height of a ball? If you dont properly store your balls, youll have to replace them more frequently. Why do golf balls bounce so high on concrete? The Physics of Grass, Clay, and Cement. Few independent variables will be changed, so the investigation is easy to manage, and the data is easier to process. Why do balls bounce higher on different surfaces? 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. Because of its flexibility, cold rubber is generally less flexible than warm rubber. The balls finish up with the same amount of energy and the only energy given out is thermal energy. Our team of volunteer scientists can help. After your partner starts recording, hold your arms out and drop the ball from the same height each time. There are more than 160 different types of tennis surfaces. As energy cannot be created or destroyed it follows that the energy must have come from the energy that the ball possesses. This is a result of the Record this result in your assignment book under trial 3 for the tennis ball. Hard court tennis demands a lot from your joints! This is because as the ball goes faster it passes through a greater volume of air each second. The drag force increases as the ball goes faster. 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. Please enter a search term in the text box. This can be explained by two factors. us. h1 = The distance between the bottom of the ball before it is dropped and the ground. But opting out of some of these cookies may affect your browsing experience. A ball bounces in an arc, so measure the height at the top of the arc of the first bounce. Why Tennis Balls Bounce. 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 is why you should have seen that when you bounced the basketball on a relatively hard surface it bounced higher (it lost less energy) compared with when it was bounced on a softer surface . 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 . 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. The higher the height from which the ball was dropped from, the higher the height to which it bounced. Bouncing is what makes playing with a ball so much fun. As the height from which the ball was dropped from was increased, the GPE energy that the ball possessed before being dropped also increased. The results are shorter rallies and quicker points. 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. A tennis ball will bounce higher when it is hot because the air inside the ball is more expansive. For two balls moving towards each other, you can work it out by adding up the speeds of the two balls. 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. It therefore hits more air particles each second and so the force of drag is bigger the faster the ball goes. 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. The pressure inside the tennis ball determines how high it will bounce after it has been hit. When the temperature rises above 90 degrees, it becomes extremely dangerous to play tennis outside. ping pong 2 cm 3 cm 2 cm 2 cm, basketball 82 cm 84 cm 80 82 Does height make a difference? Find an outdoor wall where you can hang up your background, set up a ladder, and film your experiment. Use a uniform surface to drop the ball onto. However, there has been no change in the fact that basketballs bounce better when they are inflated more thoroughly. that bounced the highest on the smooth concrete. 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. Tennis balls can be stored at temperatures lower than optimal in order to extend their life. We then bounced the balls on the surfaces and, measured the heights. We did this by bouncing different types of balls 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. Therefore, harder surfaces will ultimately bounce a ball higher. 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. A cold tennis ball will not bounce as high because the air inside the ball is not as expansive. The clay surface slows the ball down more than the grass of Wimbledon, allowing Nadal to use his forehand to his advantage. The same surface can be used to play both doubles and singles matches. One of the hunks of information we found was The balls bounced higher on the concrete Let's see if physics can explain what happens. Balls bounce in ways that are affected by gravity. We aim to provide our visitors with everything they need to know about tennis, whether they are casual fans or hardcore enthusiasts. This will be called the average of the middle three repeats. didn't catch the ball on time before it went back down to the ground, we would get 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. Try comparing two days with different atmospheric pressure. The height of the ball at each bounce is then calculated. we were able to work our way around them, giving us a more successful Science Buddies Staff. This cookie is set by GDPR Cookie Consent plugin. This will mean that I will have to have the interval between the different heights from which the ball is dropped from less than 20cm, probably at 10cm. "Balls Bouncing Off of Surfaces.". In the heat, the molecules are more active, so the ball can bounce higher . The acceleration due to gravity causes the ball to change direction and start moving downwards at stage 2. from the ball, therefore causing it to bounce higher than it normally would on dirt 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. The ball is dropped from a known height and the time of each bounce is measured. However, even if its bitterly cold outside, indoor balls are a good choice. However when the ball is dropped from a relatively low height, drag 0. The balls finish up with the same amount of energy and the only energy given out is thermal energy. Also the difference between the force of air resistance acting upon a ball travelling at 1ms-1 and the force of air resistance acting upon a ball travelling at 2ms-1 is far smaller than the difference between the force of air resistance acting upon a ball travelling at 20ms-1 and the force of air resistance acting upon a ball travelling at 21ms-1. Each of the following experiments tests a different hypothesis. The balls leave the floor at the same speed with the same amount of KE and so both balls reach the same height and end up with the same amount of GPE at the top of their bounces. 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. hard ball made of rubber should bounce the highest on a concrete surface, which Removing the maximum and minimum results and taking an average of the middle three results also provided more accurate results. on different types of surfaces, then recorded the height of the bounce. Drag is a squared function of velocity and therefore as the ball drops drag increases a greater amount each second. Will the air pressure change the bounciness of a ball? Therefore any change to the height from which the ball starts with affects the height to which it bounces to. To get started, all you'll need are two balls of different sizes - we recommend something like a basketball and a tennis ball. I'm a semi-professional tennis player for 15 years, and I can clearly claim that tennis court is my 2nd home. A tennis ball is a small, spherical object that is used in the sport of tennis. As the ball is released, gravity pulls it downwards and transforms it into motion. If it bounces up less than .5 meter, then it is more inelastic. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. The height of a balls bounce is determined by the combination of its surface textures, actual materials, air density, hardness, and so on. Once the drag force equals the gravitational force all forces are equal and acceleration stops. Masses of tennis balls range between 56.0 and 59.4 grams (2011). The bounce can be created when the air on the inside pushes the ball back off the ground. How Much Do Air Jordan Tennis Shoes Cost? If you're playing under 68 degrees, it's a good idea to make sure the ball doesn't bounce too much. I used a Flexible measuring tape to measure what the height was. bounces the highest on smooth concrete. You can check the weather stats at. Now use your data table to plot points on the graph. The maximum and minimum results were included when working out the variation between results however, seeing as the maximum and minimum results were produced by the experiment and are therefore part of the variation between results produced by the experiment. Air resistance exists but does not affect the velocity of the ball significantly. (2020, January 12). Science Buddies Staff. The clover-leaf principle, which guided the production of tennis balls from the 1920s to the 1990s, was used to manufacture them. Observe the height of the 1st rebound height of the tennis ball. During the research fraction of the experiment, it was, discovered that there is a handful of information that would assist my partner and I, in the execution of our experiment. How does the material of a ball affect its bounce? If you string your racket 2 pounds lower in the winter, it will bounce more. However, it was the basketball Write the pressure in the data table: Have your volunteer get the video camera ready. At 2ft, the basketball bounced 15 inches, the tennis ball bounced 12 inches, and the golf. Hot balls were the more likely to bounce higher than cold balls. "That's The Way The Ball Bounces," The Exploratorium Museum, San Francisco, CA. The cookie is set by GDPR cookie consent to record the user consent for the cookies in the category "Functional". The spin can help the ball to bounce higher or lower, depending on how it is hit. To a wider range of results i.e. rubber ball 39 cm 38 cm 41 cm 39 cm. Place the tape measurer against the edge of a wall using the bluetack 3. would bounce the highest on a hard, smooth concrete surface because a rubber ball by Jonah Lehrer on September 8, 2011. he official rule book of tennis is 35 pages long. If the coefficient to restitution = 0.7, a ball dropping from h1in a vacuum would reach the height of 0.7 h1 after bouncing. To be consistent, again measure to the bottom of the ball. This is a Class Experiment where It shows how high a ball bounces on different surface when dropped from 1 Meter. The bounce of a cold superball is shorter than that of a warm superball. I plan to collect at least ten results as this will make the conclusion and graph I am able to draw from the experiment more accurate than if I had less results than ten. 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. 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. 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. Internal air pressure is critical to the bounce of most tennis balls. Friday - 25/04/14 The colder the temperature, the less likely it is that the ball will bounce. The tennis balls bounce in different ways. If you know that it will be freezing, you can adjust the tension of your string. The cookie is used to store the user consent for the cookies in the category "Performance". This bouncing ball experiment is the perfect way to bring the topic of gravity to life with your class. Balls bounce in ways that are affected by gravity. Copyright 2002-2023 Science Buddies. 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. half the results (concrete), we were incorrect about the basketball. Repeat the process three times with the same ball and record results. The ultimate answer was that a basketball The effect of surface on the bounce height of a tennis ball. When the temperature is below 68 degrees, the ball will bounce less. The surface onto which the ball is dropped upon will be kept the same. 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. The felt helps to create spin on the ball when it is hit with a racket. Temperature will not affect the balls bounce either as the experiment will be conducted at room temperature, thus not allowing the floor to get cold and in doing so alter its affect upon the ball on impact. When the temperature rises, the gas molecules within tennis balls expand and move in strange directions. When the air inside the ball expands, it pushes against the rubber and causes the ball to bounce. . As an example, on the day we performed our experiment, a strong wind was The cookie is used to store the user consent for the cookies in the category "Analytics". A glass ball will bounce higher than a rubber ball if it doesnt break. 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. 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. 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 h. Do a larger amount of results; 1cm, 2cm, 3cm, 4cm etc. This is because the higher the starting height of the ball, the higher the ball's potential energy. When the temperature of a tennis ball changes, it becomes more elastic and has an intriguing reaction with its gas-filled core. Averages are more reliable than using one result as they take into account variation between results. If you were to see a ball drop to the ground in slow motion, you would see its shape change dramatically. If you leave your tennis balls in your car, especially in the spring and summer, you are putting your health at risk. Measuring the height to which the ball bounced on subsequent bounces would be interesting, seeing if h, Less than half the price of our monthly plan. Steel balls bounce higher than rubber balls. Keep your balls warm in order to get the best bounce possible. More thermal energy is also produced. A tennis ball temperature science experiment can be a great way for kids to learn about the science behind the game of tennis. 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. 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. Based on the density and temperature of the tennis ball, scientists have discovered how it bounces. The more energy that the ball possessed before being dropped, the more energy was converted into KE while the ball fell. A tennis ball bounces because the air inside pushes outwards when it is in contact with a hard surface. 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. Five repeats were done as it was deemed that an average of the middle three was reasonably accurate. 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. Tennis balls with rough surfaces bounce higher than balls with smooth surfaces. I do not believe that any ball will reach terminal velocity in this experiment seeing as the maximum height that they can be dropped from is 2m and, as the ball is quite smooth, I do not believe that it will have enough time to accelerate to its terminal velocity before it hits the floor. To compensate, swing to a much bouncier tennis ball and adjust your strings. The higher the air pressure the more air particles per cubic meter. in the execution of our experiment. For multiple bounces, it's just like dropping the ball again from a reduced height. With the same squared function of velocity and therefore as the ball when it against.
