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. When the temperature drops, gas molecules in close proximity. If you leave your tennis balls in your car, especially in the spring and summer, you are putting your health at risk. 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 cookie is set by GDPR cookie consent to record the user consent for the cookies in the category "Functional". Working out the variation in results shows how accurate the experiment was. A measuring stick/ruler marked in centimetres; long enough to record the highest ball bounce. 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. 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 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. Science Buddies: Pilobolus Spore Sac Launch. Height will be the variable that we will vary. When the ball hits the ground,the ground hits back with the same amount of force. The maximum height will have to be less than two meters as that is the maximum height that the equipment allows. order to give a fair experiment. When it is dropped, the air molecules will squish together and then spring apart. Its a great way to get some exercise while also getting some quality time with friends. The ball bounced higher on the concrete surface because of how much elastic potential energy was released from it. 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. 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. In a ball bounce experiment, a ball is dropped from a height and is allowed to bounce on a hard surface. Athletic and cardio abilities are becoming a bigger factor each season, but some players remain hard courts experts. 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. An average will then be taken. STEP4 - Watch as the smaller ball flies off into the air! Once the drag force equals the gravitational force all forces are equal and acceleration stops. that bounced the highest on the smooth concrete. Because air is a gas, when compressed, it becomes harder and pushes back harder than any other substance. 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.

I used a Flexible measuring tape to measure what the height was. "Balls Bouncing Off of Surfaces.". Keep releasing pressure and repeating the experiment until the ball no longer bounces. however, by bringing a ladder or stool to catch the balls perfectly on time. Two different types of balls, Penn Championship and Non-Championship will be compared. For a squash ball, f might be less than 0.5 or 0.25 - squash balls are not very bouncy. 1. 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. 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. Analytical cookies are used to understand how visitors interact with the website. Introduction: This is called the relative speed. h1will start at 2m and then move down in intervals of 10cm to 10cm. The force of the ball hitting the ground causes it to bounce up, because it puts an equal force on the ball. Also the mass of the ball affects the chances of the ball reaching its terminal velocity. Therefore, harder surfaces will ultimately bounce a ball higher. This would allow the actual coefficient to restitution to be calculated. You can stay in the game and avoid burning up by playing in the evenings or on a court with lighting. 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. First, you will need to draw the background for your experiment, which will act as a large ruler for measuring your bounces on video. The ball has reached its terminal velocity and cannot fall any faster (unless dropped in a vacuum). These both support my prediction and show that my prediction was correct. This is impossible. Results are presented for a tennis ball, a . faced. Section II: Hypothesis. Keep releasing pressure and repeating the experiment until the ball no longer bounces. All of the factors that could have affected the results that were uncontrollable could have produced variations between results. Record the new pressure reading in your data table and repeat steps 4 and 5. . Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. (Doherty, 1991). The longer it takes to stop, the higher it bounces to. This means that the faster that the ball travels the larger the force of air resistance upon it. Try bouncing different kinds of balls to test this question. Why Tennis Balls Bounce. In the heat, the molecules are more active, so the ball can bounce higher . Which surface bounces a ball the highest? - Measuring tape x The Swiss like to get points over and done with in a short period of time. This was when the ball was falling in air. 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. One way to measure the amount of air that is in a ball is with an air pressure gauge. 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. There were some trends observed in our This means that the faster that the ball travels the larger the force of air resistance upon it. 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 . 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. 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. ping pong 2 cm 3 cm 2 cm 2 cm, basketball 82 cm 84 cm 80 82 Concrete4. 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. Grades: Preschool and K-2. Tennis balls can be stored at temperatures lower than optimal in order to extend their life. The Tennis ball experiment - Home The Tennis ball experiment How Do Different Surfaces Effect The Bounce Of A Tennis Ball? Not only does a ball distort its shape--so does the surface on which the ball bounces. (2020, November 20). The changes in shape are due to a balance of forces and energy: "When you drop a ball, gravity pulls it toward the floor. Leave the tennis balls in place for at least one to three hours, if possible. 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 . Instead, as the ball is still always loosing GPE so long as it is still falling, all GPE is converted into thermal energy. 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. In this practical, students may use a variety of different balls to determine which type is most efficient. rubber ball would bounce the highest on concrete. 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. 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). 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. At 2ft, the basketball bounced 15 inches, the tennis ball bounced 12 inches, and the golf. Trying to figure out different things about any item, in my case bouncing balls and observing their heights. Drag is a squared function of velocity and therefore as the ball drops drag increases a greater amount each second. From the above table it can be seen that there were inaccuracies in the experiment. Push it against the measuring tape, careful to keep it at the same height. Therefore any change to the height from which the ball starts with affects the height to which it bounces to. experiment. A lot of Method:The apparatus will be set up as shown: H is the height of the ball before it is dropped. Why does a tennis ball bounce higher on concrete? Doherty, P., 1991. energy a surface absorbs, the more of it will remain for a ball to bounce. 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. Gather 15 to 20 tennis balls and a measuring tape. But what makes a ball bounce? concrete, in which we were incorrect. The approach was to place 3 tennis balls in 4 different environments with different temperatures. 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. The Racquet Sports Industry's website states that, like human fingerprints, no two balls seem to be alike, and each has slightly different bouncing ability. Use the paint and a tape measure to make a series of lines on your roll of paper. 2. With this information, we For any other use, please contact Science Buddies. 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. Please enter a search term in the text box. It should be on a smooth cement surface for optimal ball bouncing. It therefore hits more air particles each second and so the force of drag is bigger the faster the ball goes. 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. 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. 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. The cookie is used to store the user consent for the cookies in the category "Other. 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. Watch the video of the dropping tennis ball. Why does Rafael Nadal do so well on the clay? 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. Easy Experiment This scientific mystery can be demonstrated at home or school with a simple experiment. During the preliminary experiment it was established that time was not an important factor that had to be taken into account when deciding how many different heights to drop the ball from and the interval between those heights. Why Does One Tennis Shoe Pull Your Sock Down? This blew the light balls away, giving us an unvalid result or catch. As an example, on the day we performed our experiment, a strong wind was When the ball deforms, its molecules are stretched apart in some places and squeezed together in others. A tennis balls trajectory is determined by its temperature. . 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. A glass ball will bounce higher than a rubber ball if it doesnt break. Drop each ball from a distance of 1 meter onto the surface and record how high it bounces in meters (Example: .46 meters). The impact duration was between 65 and 71 ms. in the execution of our experiment. 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. When the rubber ball hits the ground it gets compressed, or squished, and because it is very elastic, it quickly returns to its original shape. When the temperature rises, the gas molecules within tennis balls expand and move in strange directions. The balls bounced higher on the concrete The reliability of our experiment wasn't so strong. The reason balls bounce is quite advanced science. You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use. 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. When the ball hits the floor and stops, that energy has to go somewhere. The tennis balls bounce in different ways. Our team of volunteer scientists can help. Using this experiment, we will attempt to determine whether the temperature of an object has an effect on its behavior. We, chose balls and surfaces with different hardnesses, textures and compositions in, order to give a fair experiment. An investigation into how they impact play on the court. Repeat step 5 with all of your other surfaces. Copyright 2002-2023 Science Buddies. 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. Students should consider the factors listed below in order to determine which type of bouncing ball is best suited for the task. Although we were correct about hypothesis, we predicted that a rubber ball would bounce the highest on rough Most people believed that concrete would have the most bounces, and mud the least. small balls sometimes, but we could have improved this by taking many attempts Method: 1. It will not have enough force to bounce if it is lit. Use the pressure gauge to release some of the air pressure from the ball. The chains stretch back out as rubber cools, allowing the original form to return. Since the concrete surface is the hardest surface, it allowed more energy to be released from the ball, therefore causing it to bounce higher than it normally would on grass. The low bounce allows him to hit his forehand with a topspin as the ball stays low and bends over the net. being able to catch the ball on time was another one of the issues we faced. The felt helps to create spin on the ball when it is hit with a racket. 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. 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. If you want to make the ball bounce higher, you can try heating it up before you play. Then when dropping the ball again eye level was kept level with the blue tack. This would mean that one could re-examine the height to which it bounced to and find it exactly instead of having to make a split second judgement which is not half as accurate. This is longer than the 5-8 ms ball bounce from a solid surface or racquet. If the drag is less the ball will fall faster and is less likely to reach its terminal velocity. surface because of how much elastic potential energy was released from it. Science Buddies Staff. A decrease in bounce is caused by a colder temperature. The reason clay courts are more effective for low-power hitters is because the ball keeps bouncing higher and higher. 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. It is a firm rectangular surface with a low net stretched across the centre. In my science fair experiment, the golf ball overall was the ball that bounced the highest. STEP1 - For comparison first hold the football and smaller ball in each hand and drop them from the same height. A hard surface like concrete absorbs less energy than a soft surface like a carpeted 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. were able to construct a successful experiment. is well-inflated and made of rubber which would give it more kinetic energy and Changes in air pressure could have affected results as could changes in temperature however changes in these two factors would have been small; air pressure would not have changed enough to affect the results in the hour period in which the experiment was conducted, and although the rooms temperature may have increased by a degree or two, due to body heat, over the course of the period temperature was not a major factor that affected the height to which the ball bounced and would not have significantly affected the results. Why do golf balls bounce so high on concrete? 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. The ball shoots up with less energy because of this. Tennis balls with rough surfaces bounce higher than balls with smooth surfaces. The higher the air pressure the more air particles per cubic meter. To get started, all you'll need are two balls of different sizes - we recommend something like a basketball and a tennis ball. If it bounces up less than .5 meter, then it is more inelastic. A ball bounces in an arc, so measure the height at the top of the arc of the first bounce. Air resistance exists but does not affect the velocity of the ball significantly. - Four surfaces (carpet, rough concrete, dirt and smooth concrete). However when the ball is dropped from a relatively low height, drag 0. Do you have specific questions about your science project? 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. 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. You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use. This is because it is the easiest and quickest variable to alter. 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. Try the experiment again, but this time change how high the ball is dropped instead of the air pressure of the ball. Launch Related Video : The Hawk Factor. However the conditions were kept the same for each drop of the ball. A cold tennis ball bounces lower than a warm one. surface bounces a ball the highest. From this it can be seen that using the average of the middle three results is more accurate than using the average of all five, as it automatically discounts most anomalies. The mass of the ball will affect the height the ball bounces to because it affects the balls starting energy. When the air inside the ball expands, it pushes against the rubber and causes the ball to bounce. The ball did not appear to reach its terminal velocity which also supports my prediction. The results are shorter rallies and quicker points. Warm up the ball before it is used to increase its bounce. Place four tennis balls in a freezer, four in a refrigerator, four at room temperature and four outside in the sun. discovered that there is a handful of information that would assist my partner and I was proven correct after our experiment. Since 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. This applies to a ball falling in a vacuum. his the height of the balls bounce. The only difference between the balls is that the ball dropped from a higher height gives out more thermal energy. Increased energy and movement results in a bounce. Therefore the height that it reaches is less high. Some of the balls energy can be converted into heat. As drag is a squared function, proportional to the square of the velocity, it is impossible to calculate the velocity that the ball hits the floor at. The coefficient to restitution can be found out from a graph of, it follows the gradient of the graph change in h. . This is correct unless the ball shows signs of reaching terminal velocity. Try comparing a hot day to a cold day. Air resistance exists but does not affect the velocity of the ball significantly. This will be called the average of the middle three repeats. Now, take your video and watch it to gather your data. Conclusion: It might be a good idea for students to experiment with a variety of balls to determine which one is most effective. The ultimate answer was that a basketball These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. changing air density, temperature. More thermal energy is also produced. To find out what affects the height to which a ball bounces. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. Focus. When the air inside the ball expands, it pushes against the rubber and causes the ball to bounce. Air density will not change enough to affect the flight of the ball seeing as all the results will be collected during a brief period on one day. This is a result of the It was decided that the first drop would start at 2m off the floor and then move down in intervals of 10cm to 10 cm off the floor. Balls change shape during play. For two balls moving towards each other, you can work it out by adding up the speeds of the two balls. A ball bounces differently on different surfaces because some surfaces absorb more energy from the ball than others. 3. When a tennis ball is on the court, the bounces are heavily influenced by the environment. A tennis court is the venue where the sport of tennis is played. The more energy absorbed by the surface, the less that remains in the ball for it to bounce. The bounce height was measured at a 90 degree viewing angle to the ruler to minimise parallax errors. 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. Is it a straight line? 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. 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 data from the experiment shows that the weight of the ball is important when bouncing. With this information, we. The higher the ball is, the more it will bounce when you warm it up in cold weather. This means that the higher h. will differ from the height that the ball would have reached had it been dropped in a vacuum. 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). use four meter sticks and go right the way up to four meters. If the ball bounces up more than .5 meter then, it is more elastic. The Graph on page 23 shows that all of the results were very close together. This is why it. This can be a great way to teach kids about the physics of tennis and how temperature affects the game. Tennis cannot be played at a certain temperature; however, 70-90 degrees Fahrenheit is ideal.
