The energy goes into deforming the ball-- from its original round shape to a squashed shape. The Swiss like to get points over and done with in a short period of time. Therefore the ball goes higher. Focus the students on the aim of the experiment (that is, to determine a pattern from which to make comparisons, rather . 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 changes in shape are due to a balance of forces and energy: "When you drop a ball, gravity pulls it toward 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. Graph 1. The higher the ball goes, the more GPE it ends up with. The maximum height will have to be less than two meters as that is the maximum height that the equipment allows. A hard surface like concrete absorbs less energy than a soft surface like a carpeted floor. The ball did not reach terminal velocity however as it did not have enough time to accelerate to its terminal velocity. It was more reliable to use the middle three results as it automatically discounted any anomalies; assuming two similar anomalies were recorded for one height, if they were then they both would be discounted. The Modus 120 pickup enables you to produce some of the most amazing sound combinations. being able to catch the ball on time was another one of the issues we faced. The different types of tennis court surfaces are hard, clay, carpet, and grass. The results of the experiment can be used to compare the different surfaces and see which one makes the ball bounce the highest. We then bounced the balls on the surfaces and It's the speed of the tennis ball compared to what it's bouncing off that's important. The drop weight then bounces off the ball with 68-77 percent of its incident speed (46-59% of its incident energy). This also proves the accuracy of the experiment. This means that the higher h. will differ from the height that the ball would have reached had it been dropped in a vacuum. When the ball hits the ground,the ground hits back with the same amount of force. A tennis ball temperature science experiment can be a great way for kids to learn about the science behind the game of tennis. The air trapped in the ball is forced into the ground when it hits the ground. From this I am able to determine that the experiment was very accurate. 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. It provided me with five repeats so that the maximum and minimum results could be discounted and a reliable average could be taken. 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. Record the new pressure reading in your data table and repeat steps 4 and 5. 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. will 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. I think this is Now work out the average of the tennis ball rebound height by adding all of the measurements for the tennis ball rebound height up and then dividing the . EQUIPMENT: 1 metre ruler 1 table tennis ball. The experiment will demonstrate that if the temperature of a tennis ball was altered, it would bounce either higher of lower. This means that the faster that the ball travels the larger the force of air resistance upon it. 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. 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. In this experiment you will use a ball filled with air. Because of this, a fully inflated ball may look deflated if the temperature drops quickly. Best hard court players of all time The only difference between the balls is that the ball dropped from a higher height gives out more thermal energy. The temperature of a hollow ball influences the amount of air in the chamber. You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use. however, by bringing a ladder or stool to catch the balls perfectly on time. However, you may visit "Cookie Settings" to provide a controlled consent. were able to construct a successful experiment. METHOD: 1. 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. Instead, as the ball is still always loosing GPE so long as it is still falling, all GPE is converted into thermal energy. The ball gains energy of motion, known as kinetic energy. 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. Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. 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. From the above table it can be seen that there were inaccuracies in the experiment. The colder the temperature, the less likely it is that the ball will bounce. 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. All rights reserved. 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. This is because it is easiest as the figure read of the meter rule is the result. - tennis ball x As they are pushed about, the molecules in the ball collide with and rub across each other." we were able to work our way around them, giving us a more successful If we rubber ball would bounce the highest on concrete. If the coefficient to restitution = 0.7, a ball dropping from h1in a vacuum would reach the height of 0.7 h1 after bouncing. Determine how high the ball rebounds on its first bounce. To be consistent, again measure to the bottom of the ball. by Jonah Lehrer on September 8, 2011. he official rule book of tennis is 35 pages long. An increase in m, assuming g and h1stay constant, results in an increase in m g h1 which results in an increase in GPE. 70% is retained. This would eliminate parallax error further. Repeat steps 1-6 with the different balls. There is an activity at home that can be used to investigatebounciness. The steel snaps back more quickly when it hits the ground. The cookie is used to store the user consent for the cookies in the category "Analytics". h1will start at 2m and then move down in intervals of 10cm to 10cm. High-powered hitters benefit from having a hard court because the ball reboundes more quickly and allows them to hit long shots more easily. These cookies track visitors across websites and collect information to provide customized ads. Use a uniform surface to drop the ball onto. In my science fair experiment, the golf ball overall was the ball that bounced the highest. Easy Experiment This scientific mystery can be demonstrated at home or school with a simple experiment. will differ from the height that the ball would have reached had it been dropped in a vacuum. As CR = h2/ h1it follows the gradient of the graph change in h2/ change in h1= CR. Does a tennis ball bounce differently on different surfaces? Some of the balls energy can be converted into heat. In the heat, the molecules are more active, so the ball can bounce higher . an incorrect and unreliable result. Tennis balls are different at sea level and at high altitudes. Gather 15 to 20 tennis balls and a measuring tape. If you are looking for a challenging sport, tennis is an excellent choice for the winter months. harder surfaces will ultimately bounce a ball higher. , v is greater therefore KE is greater by a larger amount). Balls are not round. Therefore of the GPE that the ball possessed at the beginning some energy is given off as thermal energy. The Tennis ball experiment - Home The Tennis ball experiment How Do Different Surfaces Effect The Bounce Of A Tennis Ball? Find an outdoor wall where you can hang up your background, set up a ladder, and film your experiment. It is also necessary to warm a ball, because the energy inside it is released. Use the measuring tape to measure 150 cm off the ground. his the height of the balls bounce. If it bounces up less than .5 meter, then it is more inelastic. the higher it popped up into the air. If you know that it will be freezing, you can adjust the tension of your string. 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. As in both cases the main form of energy is GPE it follows that the higher the ball is dropped from, the higher the ball will bounce. Copyright 2002-2023 Science Buddies. As a result, they move at a slower rate of speed with less energy. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. If you were to see a ball drop to the ground in slow motion, you would see its shape change dramatically. 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. You can check the weather stats at. 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. As a result, the ball is lifted in this manner. Materials 1. ball bounced 6 inches. For a squash ball, f might be less than 0.5 or 0.25 - squash balls are not very bouncy. (Doherty, 1991). 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. - Ping pong ball x Air pressure will affect the balls fall slightly as the concentration of air particles per cubic meter varies with air pressure. But how does concrete . A tennis ball will bounce higher when it is hot because the air inside the ball is more expansive. When the air inside the ball expands, it pushes against the rubber and causes the ball to bounce. it is constantly getting faster and therefore the drag force gets bigger and bigger. 2. Concrete got bounced on the most, 5 times, and the highest, 55cm. Ball trial 1 trail 2 trial 3 average However, there has been no change in the fact that basketballs bounce better when they are inflated more thoroughly. is well-inflated and made of rubber which would give it more kinetic energy and This cookie is set by GDPR Cookie Consent plugin. Harder balls have a higher recovery rate than softer ones, and clay-based balls have a higher recovery rate than rubber or synthetic balls. When a bouncing ball falls, it initially gains speed or kinetic energythe energy of motion. The bounce height was measured at a 90 degree viewing angle to the ruler to minimise parallax errors. 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. Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features. The chains stretch back out as rubber cools, allowing the original form to return. Hypothesis. Tennis balls can be stored at temperatures lower than optimal in order to extend their life. The mass of the ball will affect the height the ball bounces to because it affects the balls starting energy. Two different types of balls, Penn Championship and Non-Championship will be compared. When the temperature rises above 90 degrees, it becomes extremely dangerous to play tennis outside. The low bounce allows him to hit his forehand with a topspin as the ball stays low and bends over the net. This means that KE is the same for both balls when each ball hits the ground. For instance result 3 from 200cm was an anomaly but was not taken into account when taking the average of the middle three. This is longer than the 5-8 ms ball bounce from a solid surface or racquet. It would also be fun to explore the effect of different surfaces on the bounce of the bouncy ball. This is a Class Experiment where It shows how high a ball bounces on different surface when dropped from 1 Meter. Focus. 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. "Under Pressure: Ball Bouncing Dynamics.". According to our background research, a Make a line graph of your data. "Balls Bouncing Off of Surfaces.". 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. Click the "Experiment" button to find out! Also the mass of the ball affects the chances of the ball reaching its terminal velocity. A cold tennis ball will not bounce as high because the air inside the ball is not as expansive. Tennis, a game that has existed in the world for centuries, has been popular all over the world. Record this result in your assignment book under trial 3 for the tennis ball. The steel has a lot of bounce power due to its better storage of energy. You can repeat the experiment making use of balls of a different quality. High bounce ball 2. This did not happen in my experiment however. One way to do this is to put the ball in a bowl of hot water for a few minutes. 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. 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. Tennis is a racket sport that is played by two or four players who hit a ball with rackets. The ball shoots back up after being slowed down. Let the ball bounce until it stops, and then stop recording. (2020, January 12). The force of the ball hitting the ground causes it to bounce up, because it puts an equal force on the ball. For our wind situation, one of us stood in the direction that the breeze It does not store any personal data. it goes back into the ball, giving it more force to pop back up into the air. Why do marbles bounce so high? The variation between results was obtained by taking the minimum result away from the maximum result. Why do golf balls bounce so high on concrete? 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. Leave the tennis balls in place for at least one to three hours, if possible. Obviously, a ball won't bounce as high on carpet. Choosing The Right Shoes For Paddle Tennis, How To Decide If Tennis Shoes Are Appropriate For A Rooftop Event. 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. You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use. 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. Balls bounce in ways that are affected by gravity. 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. The strength of Nadals forehand is what makes him so good on clay. Not This website uses cookies to improve your experience while you navigate through the website. During the research fraction of the experiment, it was or carpet. the concrete surface is the hardest surface, it allowed more energy to be released A lot of Using this experiment, we will attempt to determine whether the temperature of an object has an effect on its behavior. 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. The reason balls bounce is quite advanced science. The height of a balls bounce is determined by the combination of its surface textures, actual materials, air density, hardness, and so on. When the ball is pulled toward the ground, gravity slows it down so that it doesn't bounce as many times. 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. As the ball is accelerating due to gravity, at 9.81m/s2it is constantly getting faster and therefore the drag force gets bigger and bigger. Experiment 2 is for testing the effect of air pressure. Analytical cookies are used to understand how visitors interact with the website. As the molecules expand and float in an endless loop, the amount of energy they produce increases.

It is a firm rectangular surface with a low net stretched across the centre. Balls bounce in ways that are affected by gravity. An investigation into how they impact play on the court. 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. I will drop the ball 3 Calculating the coefficient to restitution of ball hitting the floor: The coefficient to restitution can be found out from a graph of h1against h2. This causes thermal energy to be given off. Repeat step 5 with all of your other surfaces. Record the new pressure reading in your data table and repeat steps 4 and 5. 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 more energy that the ball possessed before being dropped, the more energy was converted into KE while the ball fell. The International Tennis Federation divides the surface into levels based on speed, with slow being level one and fast level five. The ball moves upwards, reaching stage 1, i.e., maximum height, and its velocity is momentarily zero. This means it will be travelling the same speed when it hits the ground. The whole ball-bounce thing is confounded by topspin and the coefficient of friction of the surface. 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. Necessary cookies are absolutely essential for the website to function properly. Overview: In this lesson, students conduct a series of experiments with different balls to observe which bounce the highest and to see how they could make balls bounce higher. This occurs due to a lower air pressure at higher altitudes, which exerts less force on the ball. What material makes a ball bounce higher? (2020, November 20). We then bounced the balls on the surfaces and, measured the heights. 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. When it is dropped, the air molecules will squish together and then spring apart. This is a result of the Science Buddies Staff. 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. The exact interval will be determined after the preliminary experiment, as will the number of heights that the ball will be dropped from. old and new tennis balls (different surface textures/ages). Gravel got bounced on the least, 1 time . The harder the court surface is, the higher the rebounded ball will be. A similar length stick, marked in 5-10cm bands of colour. These cookies will be stored in your browser only with your consent. Aim: to find out which surface bounces a ball the highest. Height will be the variable that we will vary. Will the air pressure change the bounciness of a ball? The drag force increases as the ball goes faster. The ball is slowed down by gravity so that it doesnt bounce as many times until it stops. The height of the ball at each bounce is then calculated. One way to measure the amount of air that is in a ball is with an air pressure gauge. The acceleration due to gravity causes the ball to change direction and start moving downwards at stage 2. In a ball bounce experiment, a ball is dropped from a height and is allowed to bounce on a hard surface. The tennis balls bounce in different ways. Our team of volunteer scientists can help. Is it a straight line? Therefore the height the ball bounces will be proportional to the height that the ball is dropped from up to a certain point, where the ball begins to show signs of reaching its terminal velocity before it reaches the ground. You can also try using a hair dryer to heat the ball up. Bending Plant Roots with Gravity Lesson Plan Introduction. This means that the higher h1the more h2will differ from the height that the ball would have reached had it been dropped in a vacuum. Which surface bounces a ball the highest? As the height from which the ball was dropped from was increased, the GPE energy that the ball possessed before being dropped also increased. Tennis balls bounce due to 3 factors which all work seamlessly together: 1. Now use your data table to plot points on the graph. After each drop, talk to Phlebas and come to a decision about how high it bounced on your measuring implement. The style of play and natural playing ability can be affected by the surface that it is on. In this paper, the dynamics of a bouncing ball is described for several common ball types having different bounce characteristics. For any other use, please contact Science Buddies. The ball has reached its terminal velocity and cannot fall any faster (unless dropped in a vacuum). This experiment requires a ball that will bounce and a meter stick or other measuring device. Therefore the results are valid. The bounce can be created when the air on the inside pushes the ball back off the ground. This is because it is easiest as the figure read of the meter rule is the result. Belowis the graph of h1against h2. How does the material of a ball affect its bounce? The difference between the predicted height and the actual height will provide evidence as to how air resistance affects the flight of the ball. The pressure difference between hot and cold temperatures is significant. What do you think this means about your results? 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 data from the experiment shows that the weight of the ball is important when bouncing. Therefore the coefficient to restitution = 0.7. 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 . It shows that heights were recorded that exceeded the height that the ball would have reached had it been dropped in a vacuum. Therefore the heavier the ball is, the faster its terminal velocity. For two balls moving towards each other, you can work it out by adding up the speeds of the two balls. 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. This means that not all the GPE is converted into KE as it would have been if the ball had been dropped in a vacuum. But opting out of some of these cookies may affect your browsing experience. Keep your balls warm in order to get the best bounce possible. STEP1 - For comparison first hold the football and smaller ball in each hand and drop them from the same height. Internal air pressure is critical to the bounce of most tennis balls. External factors, i.e. didn't catch the ball on time before it went back down to the ground, we would get Tennis balls should ideally be kept at temperatures greater than 68 degrees Fahrenheit or 20 degrees Celsius. Hypothesis: if different balls are bounced on different surfaces, then a rubber ball Two half-shells are molded together to form a core, which is then molded together again. Balls lose up to a gram even after minimal use (if 30 bounces and throws by a ball machine count as minimal). 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/Sports_p007/sports-science/ball-bouncing-dynamics. Do different kinds of balls bounce differently? Once the ball hits the ground, its displacement is momentarily zero. To a wider range of results i.e. Chemistry: The Central Science (Theodore E. Brown; H. Eugene H LeMay; Bruce E. Bursten; Catherine Murphy; Patrick Woodward), Psychology (David G. Myers; C. Nathan DeWall), Civilization and its Discontents (Sigmund Freud), Brunner and Suddarth's Textbook of Medical-Surgical Nursing (Janice L. Hinkle; Kerry H. Cheever), Principles of Environmental Science (William P. Cunningham; Mary Ann Cunningham), Business Law: Text and Cases (Kenneth W. Clarkson; Roger LeRoy Miller; Frank B. troubles my partner and I had during our experiment along with the problems we A tennis ball is a small, spherical object that is used in the sport of tennis. The cookie is used to store the user consent for the cookies in the category "Other. solid. When the ball deforms, its molecules are stretched apart in some places and squeezed together in others. You also have the option to opt-out of these cookies. The bounce should be between 53 and 58 inches. 3. 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. The harder the court surface is, the higher the rebounded ball will be. The children were oblivious to these . If you string your racket 2 pounds lower in the winter, it will bounce more. 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. chose balls and surfaces with different hardnesses, textures and compositions in You will need to be able to stop the video to make your measurements when the ball is at its highest point in the first bounce. This results in faster . Push it against the measuring tape, careful to keep it at the same height. The felt helps to create spin on the ball when it is hit with a racket. A totally accurate experiment would have a variation between results equal to zero however an experiment that is totally accurate needs to be conducted under conditions where air pressure and temperature remained constant, error produced by the ball falling on different parts of the linoleum floor tile (which was not totally even and thus produces inaccurate results) and human error removed by dropping the ball onto a uniform surface and using machinery to record the height to which the ball bounced to.
