Why do golf balls bounce so high on concrete? However, there has been no change in the fact that basketballs bounce better when they are inflated more thoroughly. 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. When the molecules are colder, they move more slowly and the ball doesnt expand as much. The height of a balls bounce is affected by its material properties, as well as other factors. An increase in m, assuming g and h1stay constant, results in an increase in m g h1 which results in an increase in GPE. 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. Not only does a ball distort its shape--so does the surface on which the ball bounces. B. Air resistance exists but does not affect the velocity of the ball significantly. will start at 2m and then move down in intervals of 10cm to 10cm. The temperature of the tennis ball has an impact on its bounce. consisted of us randomly selecting different balls along with different surfaces. Science Buddies Staff. This website uses cookies to improve your experience while you navigate through the website. Then when dropping the ball again eye level was kept level with the blue tack. Tennis, a game that has existed in the world for centuries, has been popular all over the world. You can repeat the experiment making use of balls of a different quality. The decision for the size of interval and the amount of results collected will depend upon the time taken to conduct the experiment and any other factors that may become apparent during the preliminary experiment. Tennis cannot be played at a certain temperature; however, 70-90 degrees Fahrenheit is ideal. 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. 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. Air resistance exists but does not affect the velocity of the ball significantly. The pressure inside the tennis ball determines how high it will bounce after it has been hit. The ball moves upwards, reaching stage 1, i.e., maximum height, and its velocity is momentarily zero. Write each measurement in the data table. If you play in hot weather, your balls may bounce significantly more. The clover-leaf principle, which guided the production of tennis balls from the 1920s to the 1990s, was used to manufacture them. Most experiments investigate the effect of an independent variable on a dependent variable. Decide on a height you want to drop the balls from . The higher the ball goes, the more GPE it ends up with. This is why it h2will be from the bottom of the ball as it hits the floor to the bottom of the ball at the top of its arc after bouncing. 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 ultimate answer was that a basketball 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. An average will then be taken. Aim: to find out which surface bounces a ball the highest. H is the height of the ball before it is dropped. As the ball falls it hits against air particles. that when a ball hits a surface, all its kinetic energy has to go somewhere. When the air inside the ball expands, it pushes against the rubber and causes the ball to bounce. Aim:To find out what affects the height to which a ball bounces. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. The bounce of the ball is a major factor in the game of tennis. Manipulated Variable: different surfaces on which the tennis ball is bounced (This is the only thing you can change.) Keep releasing pressure and repeating the experiment until the ball no longer bounces. Air pressure will affect the balls fall slightly as the concentration of air particles per cubic meter varies with air pressure. (Doherty, 1991). 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. an incorrect and unreliable result. A tennis balls trajectory is determined by its temperature. A hard surface, such as concrete, absorbs less energy compared with a soft surface, such as a carpeted floor. It was difficult to get down to the exact level of the blue tack seeing as it meant lowering your entire upper body in the short amount of time taken for the ball to hit the floor and rebound again to get your eye level from h1 to h2 (where the blue tack was stuck, approximately). This experiment would provide me with more results that are relevant to the experiment that I have already conducted. This would allow the actual coefficient to restitution to be calculated. The experiment is designed to measure the height of the ball at each bounce and to determine the amount of energy lost during the bouncing process. Kinetic energy and ball shape. As a result, they move at a slower rate of speed with less energy. Balls are not round. Try comparing two days with different atmospheric pressure. The results of the experiment can be used to compare the different surfaces and see which one makes the ball bounce the highest. Try bouncing different kinds of balls to test this question. Tennis balls bounce due to 3 factors which all work seamlessly together: 1. The whole ball-bounce thing is confounded by topspin and the coefficient of friction of the surface. This is correct unless the ball shows signs of reaching terminal velocity. 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. A similar length stick, marked in 5-10cm bands of colour. 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. Therefore the height that it reaches is less high.

Friday - 25/04/14 The strength of Nadals forehand is what makes him so good on clay. It therefore hits more air particles each second and so the force of drag is bigger the faster the ball goes. Overall, our experiment taught us that harder However, it was the basketball 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. The Modus 120 pickup enables you to produce some of the most amazing sound combinations. 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. The more energy that the ball possessed before being dropped, the more energy was converted into KE while the ball fell. use four meter sticks and go right the way up to four meters. 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. Each can from the same manufacturer can be different. 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. Balls change shape during play. small balls sometimes, but we could have improved this by taking many attempts Best hard court players of all time 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. catcher to catch the balls. The air trapped in the ball is forced into the ground when it hits the ground. Use the pressure gauge to release some of the air pressure from the ball. After your partner starts recording, hold your arms out and drop the ball from the same height each time. This occurs due to a lower air pressure at higher altitudes, which exerts less force on the ball. We did this by bouncing different types of balls The temperature of the balls varies depending on their origin, but heated balls bounce the most, room temperature balls the least, and refrigerated balls the most. Do you have specific questions about your science project? 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. 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. 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. Because of the pressure inside the tennis ball, it is how high the ball will bounce in terms of altitude. Gather 15 to 20 tennis balls and a measuring tape. In the heat, the molecules are more active, so the ball can bounce higher . Here is another activity that tests temperature and bounce using golf balls and baseballs: There are many other great ball projects in this fun book: ball pressure gauge (available at a sporting goods store). - Measuring tape x It does not store any personal data. Find a clear space to work in. 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. Different courts are better suited to each players style. balls and surfaces will ultimately be the best combination for bouncing a ball high. Why Does One Tennis Shoe Pull Your Sock Down? Drag is a squared function of velocity and therefore as the ball drops drag increases a greater amount each second. However when the ball is dropped from a relatively low height, drag 0. You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use. 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. The cookie is used to store the user consent for the cookies in the category "Analytics". Concrete will help bounce a ball the highest as it's hard and highest on hard, smooth surfaces. The results are shorter rallies and quicker points. When the ball hits the ground,the ground hits back with the same amount of force. - Pencil x The Tennis ball experiment - Home The Tennis ball experiment How Do Different Surfaces Effect The Bounce Of A Tennis Ball? present. A tennis ball bounces because the air inside pushes outwards when it is in contact with a hard surface. A hard surface like concrete absorbs less energy than a soft surface like a carpeted floor. "Balls Bouncing Off of Surfaces.". would bounce the highest on a hard, smooth concrete surface because a rubber ball The air pressure within the hollow ball changes as the temperature rises. What material makes a ball bounce higher? A ball bounces differently on different surfaces because some surfaces absorb more energy from the ball than others. During the research fraction of the experiment, it was Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. At 2ft, the basketball bounced 15 inches, the tennis ball bounced 12 inches, and the golf. Conclusion: Carefully climb the ladder with the ball. As they are pushed about, the molecules in the ball collide with and rub across each other." This is because it is easiest as the figure read of the meter rule is the result. It is a firm rectangular surface with a low net stretched across the centre. Removing the maximum and minimum results and taking an average of the middle three results also provided more accurate results. The effect of surface on the bounce height of a tennis ball. Does a tennis ball bounce differently on different surfaces? This is because as the ball goes faster it passes through a greater volume of air each second. Tiles3. 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. 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. Try your bounce test in different weather conditions. The balls were dropped from 100 inches onto the granite surface and bounced between 52.93 and 58.43 inches. 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. energy a surface absorbs, the more of it will remain for a ball to bounce. Hot balls were the more likely to bounce higher than cold balls. half the results (concrete), we were incorrect about the basketball. Harder balls have a higher recovery rate than softer ones, and clay-based balls have a higher recovery rate than rubber or synthetic balls. The balls finish up with the same amount of energy and the only energy given out is thermal energy. . Some of the balls energy can be converted into heat. A ball bounces in an arc, so measure the height at the top of the arc of the first bounce. The ball weighs exactly 2.5g. Place one of the tennis balls in the freezer for 20 mins 2. The bounce of a cold superball is shorter than that of a warm superball. Internal air pressure is critical to the bounce of most tennis balls. concur, which was catching the small balls. It will not have enough force to bounce if it is lit. This means that we can approximately calculate the amount of energy that the ball conserves as it hits the floor and therefore the height to which it will bounce for any given height in a vacuum. are 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. You will use an air pump, a basketball, and an air pressure gauge to test if changing the air pressure will change the bounciness of the ball. Science Buddies Staff. 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. Also it will affect its bouncing properties. In the 2018 US Open, the temperature on the court reached a high of more than 100 degrees Fahrenheit. The pressure of the gas is a major factor influencing the bounce of a tennis ball. The temperature of a tennis ball greatly affects how high it bounces. If you were to see a ball drop to the ground in slow motion, you would see its shape change dramatically. The mass of the ball will affect the height the ball bounces to because it affects the balls starting energy. found that different surfaces absorb different amounts of energy, and the less Students should consider the factors listed below in order to determine which type of bouncing ball is best suited for the task. Repeat step 5 with all of your other surfaces. If you are looking for a challenging sport, tennis is an excellent choice for the winter months. Section II: Hypothesis. September 28, 2022 by George Jackson. The colder, the lower the ball bounces, and vice versa. Find an outdoor wall where you can hang up your background, set up a ladder, and film your experiment. High bounce ball 2. When printing this document, you may NOT modify it in any way. 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. There is a chance that you will bounce. Doherty, P., 1991. How does the material of a ball affect its bounce? At 3ft, the basketball bounced 20 inches, the tennis ball bounced. 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. The grass does not provide as much upward rebound when the ball hits it. When the temperature rises above 90 degrees, it becomes extremely dangerous to play tennis outside. Does the weather make a difference? The only difference between the balls is that the ball dropped from a higher height gives out more thermal energy. What do you think this means about your results? Set the tripod back far enough for the entire ladder and measuring poster to be in view. It will be vinyl tiling. Do you have specific questions about your science project? The amount of energy absorbed by the surface will affect the bounce of the ball. Each ball in a can is different in weight, diameter, and bounce. We use cookies and those of third party providers to deliver the best possible web experience and to compile statistics. Balls bounce in ways that are affected by gravity. Science Buddies Staff. These two results were excluded when averages were being calculated and therefore the average variation between results used for calculating the average was even less than 3cm. Analytical cookies are used to understand how visitors interact with the website. I will drop the ball 3 Based on the density and temperature of the tennis ball, scientists have discovered how it bounces. 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. When it reaches Earth, it collides head-on with an . The same square of tiling will be used throughout the experiment so that inconsistencies between different floor tiles do not affect results. Although we were correct about One of the hunks of information we found was, it goes back into the ball, giving it more force to pop back up into the air. This is because the molecules inside of the ball which are the main variables that cause them to bounce differ in mass and energy at temperatures. his the height of the balls bounce. The ball has reached its terminal velocity and cannot fall any faster (unless dropped in a vacuum). Gravel got bounced on the least, 1 time . 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. Averages are more reliable than using one result as they take into account variation between results. 1 tennis ball 1 golf ball. rubber ball 39 cm 38 cm 41 cm 39 cm. is well-inflated and made of rubber which would give it more kinetic energy and The colder the temperature, the less likely it is that the ball will bounce. For our wind situation, one of us stood in the direction that the breeze Belowis the graph of h1against h2. Some of the kinetic energy of the ball is lost during the collision with the floor and the ball will not return to the original height. Keep releasing pressure and repeating the experiment until the ball no longer bounces. We then bounced the balls on the surfaces and Not This is impossible. To find out what affects the height to which a ball bounces. Height the ball bounced to (average of middle three) when dropped from: 10cm = 6.7 6.7 = 66% of 10 (to the nearest percent), 20cm = 14.0 14.0 = 70% of 20 (to the nearest percent), 30cm = 22.3 22.3 = 74% of 30 (to the nearest percent). 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. Aim: to find out which surface bounces a ball the highest. A ball that is dropped in air however is subjected to air resistance which affects the height to which it bounces. This means it will be travelling the same speed when it hits the ground. 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 slim taper of the KBS S Taper acoustic guitar makes it simple to play and hold. (2020, January 12). Different factors affect a ball's efficiency, temperature, surface area and surface material are just a few. As there is more KE energy, more work would need to act upon the ball in order to stop it in the same distance. When it is dropped, the air molecules will squish together and then spring apart. For any other use, please contact Science Buddies. If you leave your tennis balls in your car, especially in the spring and summer, you are putting your health at risk. 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. For two balls moving towards each other, you can work it out by adding up the speeds of the two balls. didn't catch the ball on time before it went back down to the ground, we would get In my science fair experiment, the golf ball overall was the ball that bounced the highest. 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. The Swiss like to get points over and done with in a short period of time. Necessary cookies are absolutely essential for the website to function properly. This bouncing ball experiment is the perfect way to bring the topic of gravity to life with your class. The weight and material of the ball will be kept the same throughout the experiment by using the same ball. By clicking Accept All, you consent to the use of ALL the cookies. As gravity remains the same the amount of work acting on the ball remains the same (apart from slightly more air resistance due to the ball travelling faster and so hitting more air particles per second, but the effect of this is negligible) and the ball travels further before stopping. After the ball reaches terminal velocity, no more GPE is converted into KE is the ball cannot get any faster. There are more than 160 different types of tennis surfaces. All rights reserved.
