The experiment was conducted as the method (below) states. 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. At 2ft, the basketball bounced 15 inches, the tennis ball bounced 12 inches, and the golf. This would allow the actual coefficient to restitution to be calculated. Therefore the ball goes higher. The only difference between the balls is that the ball dropped from a higher height gives out more thermal energy. For instance, you can use old balls for the second round of the experiment compared to new balls. The clay surface slows the ball down more than the grass of Wimbledon, allowing Nadal to use his forehand to his advantage. (Doherty, 1991). 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. Concrete got bounced on the most, 5 times, and the highest, 55cm. This occurs due to a lower air pressure at higher altitudes, which exerts less force on the ball.

Balls change shape during play. As they are pushed about, the molecules in the ball collide with and rub across each other." All of the factors that could have affected the results that were uncontrollable could have produced variations 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. 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. Different courts are better suited to each players style. 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. Line up the top of the table tennis ball with the top of the metre ruler (i.e. The temperature of the tennis ball has an impact on its bounce. Try comparing a hot day to a cold day. 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. 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. 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. How can you measure the height a ball bounces? Drag is a squared function of velocity and therefore as the ball drops drag increases a greater amount each second. This means that KE is the same for both balls when each ball hits the ground. Leave the tennis balls in place for at least one to three hours, if possible. surface bounces a ball the highest. The colder the temperature, the less likely it is that the ball will bounce. What affects ball bounce? These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. This therefore provides accurate and reliable results. Some of the balls energy can be converted into heat. This will hopefully discount any anomalies automatically and leave us with three accurate and reliable results. 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. 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. If you are looking for a challenging sport, tennis is an excellent choice for the winter months. 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. 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. But what makes a ball bounce? Section II: Hypothesis. Working out the variation in results shows how accurate the experiment was. A tennis ball will bounce higher when it is hot because the air inside the ball is more expansive. Measuring tape 3. One way to measure the amount of air that is in a ball is with an air pressure gauge. The steel snaps back more quickly when it hits the ground. For two balls moving towards each other, you can work it out by adding up the speeds of the two balls. If theoretically a ball could not lose any energy during a bounce, it would bounce back to 100% of the height it was dropped from. Then when dropping the ball again eye level was kept level with the blue tack. The higher the height from which the ball was dropped from, the higher the height to which it bounced. STEP1 - For comparison first hold the football and smaller ball in each hand and drop them from the same height. Does it slope up or down? 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. Cold balls tend to have a bouncier texture. 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. Once the drag force equals the gravitational force all forces are equal and acceleration stops. You can even play tennis outside in any weather. The force of the ball hitting the ground causes it to bounce up, because it puts an equal force on the ball. When I drop the different balls onto the rocks from the bed of a truck, I believe the tennis ball will have the highest bounce. Although catching small balls was an issue, we solved it by getting our better For our wind situation, one of us stood in the direction that the breeze When the temperature is below 68 degrees, the ball will bounce less. When it is dropped, the air molecules will squish together and then spring apart. Drop (do not throw) the ball from a carefully measured height using the meter stick. This blew the light balls away, giving us an unvalid result or catch. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. 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. Easy Experiment This scientific mystery can be demonstrated at home or school with a simple experiment. Two different types of balls, Penn Championship and Non-Championship will be compared. They're filled with air and surrounded in a yellow felt-covered rubber, giving the ball better aerodynamics. , v is greater therefore KE is greater by a larger amount). Aim: to find out which surface bounces a ball the highest. The steel ball on an unvarnished pine wood floor may not bounce at all, but rather make a dent, and so what the floor is made out of makes quite a lot of difference. This website uses cookies to improve your experience while you navigate through the website. I will drop the ball 3 The approach was to place 3 tennis balls in 4 different environments with different temperatures. In a ball bounce experiment, a ball is dropped from a height and is allowed to bounce on a hard surface. The height of the ball at each bounce is then calculated. A lot of, Community Health and Population-Focused Nursing Field Experience (C229), Introduction to Environmental Sciences (ENVS 1301), Fundamentals of Information Technology (IT200), Clinical - RN Concept-Based Transition to Professional Nursing Practice (RNSG 1263), Introduction To Computer And Information Security (ITO 310), Primary Care Of The Childbearing (NR-602), Professional Nursing Practicum (NUR - 4836C), Legal Issues in Information Security (C 841), Electrical Machines and Power Electronic Drives (E E 452), Healthcare Strategic Management and Policy (HCM415), Strategic Human Resource Management (OL600), Professional Application in Service Learning I (LDR-461), Advanced Anatomy & Physiology for Health Professions (NUR 4904), Principles Of Environmental Science (ENV 100), Operating Systems 2 (proctored course) (CS 3307), Comparative Programming Languages (CS 4402), Business Core Capstone: An Integrated Application (D083), Civ Pro Flowcharts - Civil Procedure Flow Charts, C228 Task 2 Cindy - Bentonville - Passed with no revisions, 3.1.6 Practice Comparing Executive Organizations, Database Systems Design Implementation and Management 9th Edition Coronel Solution Manual, 1-2 Problem Set Module One - Income Statement, Mini Virtual Lab Calculating GPP and NPP1, Leadership class , week 3 executive summary, I am doing my essay on the Ted Talk titaled How One Photo Captured a Humanitie Crisis https, School-Plan - School Plan of San Juan Integrated School, SEC-502-RS-Dispositions Self-Assessment Survey T3 (1), Techniques DE Separation ET Analyse EN Biochimi 1. The aim of the experiment my partner and I performed was to find out which Is it a straight line? 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. The steel has a lot of bounce power due to its better storage of energy. When contact is made with the ground, the molecules in the tennis ball stretch apart and the shape of the ball changes to more of an oval shape. Although we were correct about To be consistent, again measure to the bottom of the ball. were able to construct a successful experiment. A glass ball will bounce higher than a rubber ball if it doesnt break. The cookie is used to store the user consent for the cookies in the category "Performance". Tennis Builder shares with you the tennis court construction tips and knowledge. Introduction: Tennis balls are more likely to bounce on grass. 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. The impact duration was between 65 and 71 ms. carpet, tennis 57 cm 56 cm 61 cm 58 cm In this practical, students may use a variety of different balls to determine which type is most efficient. It will be vinyl tiling. 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. A tennis ball is made of rubber and is covered with felt. Warmer balls bounce better than cold ones. External factors, i.e. didn't catch the ball on time before it went back down to the ground, we would get It should be on a smooth cement surface for optimal ball bouncing. It shows that heights were recorded that exceeded the height that the ball would have reached had it been dropped in a vacuum. The colder, the lower the ball bounces, and vice versa. The ball has reached its terminal velocity and cannot fall any faster (unless dropped in a vacuum). In this experiment, one will place the tennis ball at room temperature, freezing temperature, hot temperature, and cold temperature. 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 force of the ball hitting the ground causes it to bounce up, because it puts an equal force on the ball. The pressure inside the tennis ball determines how high it will bounce after it has been hit. The more energy that the ball possessed before being dropped, the more energy was converted into KE while the ball fell. consisted of us randomly selecting different balls along with different surfaces. Keep releasing pressure and repeating the experiment until the ball no longer bounces. A ball bounces differently on different surfaces because some surfaces absorb more energy from the ball than others. When it hits the ground, the bottom of the ball becomes flat against the floor. Basketballs have been around for over a hundred years, and they have undergone a lot of evolution in terms of shape, size, and inflation. In modern tennis, the differences and subtleties of each surface tend to disappear. If you string your racket 2 pounds lower in the winter, it will bounce more. A decrease in h1, assuming g and m stay constant, results in a decrease in m g h1which results in a decrease in GPE. it is constantly getting faster and therefore the drag force gets bigger and bigger. The results of the experiment were obtained with a method that ensured that every drop was under similar conditions which ensured a fair test. This was when the ball was falling in air. Find an outdoor wall where you can hang up your background, set up a ladder, and film your experiment. Because of this, a fully inflated ball may look deflated if the temperature drops quickly. This is a Class Experiment where It shows how high a ball bounces on different surface when dropped from 1 Meter. The cookie is used to store the user consent for the cookies in the category "Analytics". Try your bounce test in different weather conditions. Does height make a difference? Therefore the ball ends up with more GPE, , assuming g and m stay constant, results in an increase in m g h, , assuming g and m stay constant, results in a decrease in m g h, As the ball is accelerating due to gravity, at 9.81m/s. The coefficient to restitution can be found out from a graph of, it follows the gradient of the graph change in h. . More thermal energy is also produced. Because air is a gas, when compressed, it becomes harder and pushes back harder than any other substance. Hypothesis: if different balls are bounced on different surfaces, then a rubber ball would bounce the highest on a hard, smooth concrete surface because a rubber ball is well-inflated and made of rubber which would give it more kinetic energy and less air resistance. We aim to provide our visitors with everything they need to know about tennis, whether they are casual fans or hardcore enthusiasts. The average variation between results was 3cm. The cookie is used to store the user consent for the cookies in the category "Other. 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). The Physics of Grass, Clay, and Cement. This is why it. All rights reserved. the concrete surface is the hardest surface, it allowed more energy to be released energy a surface absorbs, the more of it will remain for a ball to bounce. harder surfaces will ultimately bounce a ball higher. For any other use, please contact Science Buddies. was proven correct after our experiment. This is a result of the This is because it is the easiest and quickest variable to alter. troubles my partner and I had during our experiment along with the problems we We use cookies and those of third party providers to deliver the best possible web experience and to compile statistics. 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. However the conditions were kept the same for each drop of the ball. A cold ball will bounce farther than a warm one. It might be a good idea for students to experiment with a variety of balls to determine which one is most effective. Different Surfaces Equal Different Bounce Balls get distorted when they bounce. Now use your data table to plot points on the graph. In my science fair experiment, the golf ball overall was the ball that bounced 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. h1 = The distance between the bottom of the ball before it is dropped and the ground. 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. You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use. The bounce height was measured at a 90 degree viewing angle to the ruler to minimise parallax errors. When the ball is pulled toward the ground, gravity slows it down so that it doesn't bounce as many times. 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 . 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. Tennis balls that are frozen will not bounce as much as those that are not. Then they would be dropped from a table, and the height would be measured. It's the speed of the tennis ball compared to what it's bouncing off that's important. An increase in h1, assuming g and m stay constant, results in an increase in m g h1 which results in an increase in GPE. Write each measurement in the data table. Few independent variables will be changed, so the investigation is easy to manage, and the data is easier to process. Copyright 2002-2023 Science Buddies. This is called the relative speed. If the coefficient to restitution = 0.7, a ball dropping from h1in a vacuum would reach the height of 0.7 h1 after bouncing. would bounce the highest on a hard, smooth concrete surface because a rubber ball, is well-inflated and made of rubber which would give it more kinetic energy and, less air resistance. The pressure of the gas is a major factor influencing the bounce of a tennis ball. Click the "Experiment" button to find out! Balls bounce in ways that are affected by gravity. This means that the higher h. will differ from the height that the ball would have reached had it been dropped in a vacuum. The results are shorter rallies and quicker points. Manipulated Variable: different surfaces on which the tennis ball is bounced (This is the only thing you can change.) 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. Kinetic energy and ball shape. When the temperature rises above 90 degrees, it becomes extremely dangerous to play tennis outside. Five repeats were done as it was deemed that an average of the middle three was reasonably accurate. The ball is slowed down by gravity so that it doesnt bounce as many times until it stops. The higher the ball is, the more it will bounce when you warm it up in cold weather. Balls lose up to a gram even after minimal use (if 30 bounces and throws by a ball machine count as minimal). Concrete will help bounce a ball the highest as it's hard and If you play in hot weather, your balls may bounce significantly more. Vacuum pump, rigid plastic cylinder, two large rubber bungs to fit over the two ends of the plastic cylinder, table tennis ball, Two meter stick rulers. bounces the highest on smooth concrete. (2020, November 20). old and new tennis balls (different surface textures/ages). we were able to work our way around them, giving us a more successful Above this point the height all balls will bounce to will not be directly proportional to the height they are dropped from, but the increase in the height they bounce to will increase more slowly in proportion to the height they are dropped from compared to the increase between lower heights before the ball shows signs of approaching its terminal velocity before it hits the ground. the higher it popped up into the air. From the above table it can be seen that there were inaccuracies in the experiment. Length of Lesson: 30 - 45 minutes. Some balls to try are: soccer, basketball, volleyball, golf, tennis, or handball. Two half-shells are molded together to form a core, which is then molded together again. 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. 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. As the ball hits the blades of grass, they bend and don't provide as much upward rebound. The difference between the predicted height and the actual height will provide evidence as to how air resistance affects the flight of the ball. Take a ball and place it on the 150 cm line and drop it. From this I am able to determine that the experiment was very accurate. Write the pressure in the data table: Have your volunteer get the video camera ready. 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. Please enter a search term in the text box. Hot balls were the more likely to bounce higher than cold balls. faced. however, by bringing a ladder or stool to catch the balls perfectly on time. The ball did not reach terminal velocity however as it did not have enough time to accelerate to its terminal velocity. Hypothesis. Answer (1 of 2): Some surfaces absorb more energy than others do. As a result, the ball is lifted in this manner. the initial bounce height is 1 m). Find a clear space to work in. 15 inches, and the golf ball bounced 26 inches. Science Buddies Staff. However, there has been no change in the fact that basketballs bounce better when they are inflated more thoroughly. Therefore, our hypothesis was refuted by our final results. 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. If the ball bounces up more than .5 meter then, it is more elastic. For a squash ball, f might be less than 0.5 or 0.25 - squash balls are not very bouncy. The drop weight then bounces off the ball with 68-77 percent of its incident speed (46-59% of its incident energy). 1. 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. This was added onto another issue we had to Try the experiment again, but this time change how high the ball is dropped instead of the air pressure of the ball. SCIENTIFIC Method Aim & Hypothesis Method Variables Risk Assessment Results Conclusion & discussion 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 style of play and natural playing ability can be affected by the surface that it is on. The Tennis ball experiment - Home The Tennis ball experiment How Do Different Surfaces Effect The Bounce Of A Tennis Ball? The children were oblivious to these . Our team of volunteer scientists can help. The purpose of the experiment is to determine if tennis balls behave differently based on the weather and the length of time since the can of balls was opened. Try bouncing different kinds of balls to test this question. Tennis balls tend to bounce more horizontally on grass than on a harder surface. 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. It relates to how much energy balls have, what they are made of, how they change shape and where the energy they have goes. The ball gains energy of motion, known as kinetic energy. Note whether the ball and surface showed more of an elastic or inelastic collision. If the KE is the same as they hit the ground the energy stored in the ball as elastic potential energy will be the same also. 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. 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. Results are presented for a tennis ball, a . 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. 70% is retained. The cookie is set by GDPR cookie consent to record the user consent for the cookies in the category "Functional". 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 . Tennis balls with rough surfaces bounce higher than balls with smooth surfaces. There were some trends observed in our 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 . Gravel got bounced on the least, 1 time . We an incorrect and unreliable result. The trip is going to be thoroughly enjoyable. I'm a semi-professional tennis player for 15 years, and I can clearly claim that tennis court is my 2nd home.
