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. 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. . Experiment Click the following buttons to skip to a page. The balls bounced higher on the concrete Why do balls bounce higher on different surfaces? 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. 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. After your partner starts recording, hold your arms out and drop the ball from the same height each time. 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. This means for the ball to reach terminal velocity the drag force has to be bigger and for the drag force to be bigger the ball has to fall faster (so that more air particles hit the ball every second). When printing this document, you may NOT modify it in any way. - Paper x Then when dropping the ball again eye level was kept level with the blue tack. 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. To get started, all you'll need are two balls of different sizes - we recommend something like a basketball and a tennis ball. Then when dropping the ball again eye level will be kept level with the blue tack thus avoiding parallax errors. From this I am able to determine that the experiment was very accurate. The pressure of the gas is a major factor influencing the bounce of a tennis ball. But opting out of some of these cookies may affect your browsing experience. September 28, 2022 by George Jackson. Why do balls bounce higher on different surfaces? Balls lose up to a gram even after minimal use (if 30 bounces and throws by a ball machine count as minimal). 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. 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. As CR = h2/ h1it follows the gradient of the graph change in h2/ change in h1= CR. This is because it is easiest as the figure read of the meter rule is the result. Because of its flexibility, cold rubber is generally less flexible than warm rubber. Do different kinds of balls bounce differently? 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. Its not just a game for the wealthy; its also a game for everyone. Also it will affect its bouncing properties. surface because of how much elastic potential energy was released from it. Will the air pressure change the bounciness of a ball? For our wind situation, one of us stood in the direction that the breeze Does a tennis ball bounce differently on different surfaces? This experiment would provide me with more results that are relevant to the experiment that I have already conducted. order to give a fair experiment. Cold balls tend to have a bouncier texture. . Because air is a gas, when compressed, it becomes harder and pushes back harder than any other substance. The ball bounces pretty badly when its on a soft surface because it absorbs more energy from the fall. We then bounced the balls on the surfaces and Explanation: When all three balls are dropped from the same height, the rubber ball will bounce the highest because it has the greatest elasticity. h1 = The distance between the bottom of the ball before it is dropped and the ground. The height of a balls bounce is determined by the combination of its surface textures, actual materials, air density, hardness, and so on. 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. 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. Our team of volunteer scientists can help. 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. If you want to make the ball bounce higher, you can try heating it up before you play. If you were to see a ball drop to the ground in slow motion, you would see its shape change dramatically. The ball weighs exactly 2.5g. Some balls to try are: soccer, basketball, volleyball, golf, tennis, or handball. Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. The children were oblivious to these . Warm up the ball before it is used to increase its bounce. The bouncing of a tennis ball on a tennis court surface is analysed by making several simplifying assumptions about the physics of the interaction. Aim:To find out what affects the height to which a ball bounces. 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. A ball bounces in an arc, so measure the height at the top of the arc of the first bounce. If the drag is less the ball will fall faster and is less likely to reach its terminal velocity. Bouncing is what makes playing with a ball so much fun. Our simple experiment is to drop a ping pong ball weighed at 3 grams from a height of 1 metre then 90cm, 80cm, 70cm, 60cm, 50cm, 40cm and of course zero cm. A ball that is dropped in air however is subjected to air resistance which affects the height to which it bounces. Once the drag force equals the gravitational force all forces are equal and acceleration stops. 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. 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 trip is going to be thoroughly enjoyable. Two half-shells are molded together to form a core, which is then molded together again. solid. Chemistry: The Central Science (Theodore E. Brown; H. Eugene H LeMay; Bruce E. Bursten; Catherine Murphy; Patrick Woodward), Psychology (David G. Myers; C.

Cheever), Principles of Environmental Science (William P. Cunningham; Mary Ann Cunningham), Business Law: Text and Cases (Kenneth W. Clarkson; Roger LeRoy Miller; Frank B. - Sticky tape - 1 roll. All rights reserved. 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. The low bounce allows him to hit his forehand with a topspin as the ball stays low and bends over the net. Therefore, our hypothesis was refuted by our final results. Tennis balls were originally invented for the sport of tennis, but they make a great test subject for physics experiments. his the height of the balls bounce. 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. Therefore the coefficient to restitution = 0.7. Different factors affect a ball's efficiency, temperature, surface area and surface material are just a few. Answer (1 of 2): Some surfaces absorb more energy than others do. 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. measured the heights. Therefore the energy that the ball hits the floor with = mh, The proportion of energy lost when ball hits the floor = The Coefficient to the restitution of the two objects (C, All of the energy that the ball leaves the floor with is converted back into GPE, If dropping a ball in a vacuum all you need to know in order to know how high the ball will bounce to is h, can be found out by looking at a graph, the gradient, as a percentage of 1 gives the amount of energy conserved and therefore C. The clamp stand will be clamped down to the desk using a g-clamp to prevent it falling over and causing possible injuries. The ball moves upwards, reaching stage 1, i.e., maximum height, and its velocity is momentarily zero. Instead, as the ball is still always loosing GPE so long as it is still falling, all GPE is converted into thermal energy. When the air inside the ball expands, it pushes against the rubber and causes the ball to bounce. Push it against the measuring tape, careful to keep it at the same height. Tennis balls are more likely to bounce on grass. Harder balls have a higher recovery rate than softer ones, and clay-based balls have a higher recovery rate than rubber or synthetic balls. There is an activity at home that can be used to investigatebounciness. Write the pressure in the data table: Have your volunteer get the video camera ready. 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). When the ball hits the floor and stops, that energy has to go somewhere. 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. Therefore, harder surfaces will ultimately bounce a ball higher. Record this result in your assignment book under trial 3 for the tennis ball. This means that the faster that the ball travels the larger the force of air resistance upon it. 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. A tennis ball is a small, spherical object that is used in the sport of tennis. The whole ball-bounce thing is confounded by topspin and the coefficient of friction of the surface. Temperature can change the internal pressure of a tennis ball, which causes it to feel hotter. This therefore provides accurate and reliable results. 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. 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. The cookies is used to store the user consent for the cookies in the category "Necessary". 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 longer it takes to stop, the higher it bounces to. was proven correct after our experiment. found that different surfaces absorb different amounts of energy, and the less - Rubber ball x After the ball reaches terminal velocity, no more GPE is converted into KE is the ball cannot get any faster. With this information, we. Hot balls were the more likely to bounce higher than cold balls. When the ball deforms, its molecules are stretched apart in some places and squeezed together in others. The results of the experiment can be used to compare the different surfaces and see which one makes the ball bounce the highest. There were some trends observed in our This would allow one to find the terminal velocity of the ball. to find out which surface bounces a ball the highest. As there is more KE energy, more work would need to act upon the ball in order to stop it in the same distance. Drag is a squared function of velocity and therefore as the ball drops drag increases a greater amount each second. 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. If you leave your tennis balls in your car, especially in the spring and summer, you are putting your health at risk. or carpet. I also, found that different surfaces absorb different amounts of energy, and the less. But what makes a ball bounce? Make a note of which one bounces up higher and how high they bounce! Air resistance exists but does not affect the velocity of the ball significantly. 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. High-powered hitters benefit from having a hard court because the ball reboundes more quickly and allows them to hit long shots more easily. The tennis balls bounce in different ways. This is because as the ball goes faster it passes through a greater volume of air each second. Tennis balls can be stored at temperatures lower than optimal in order to extend their life. 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. The balls finish up with the same amount of energy and the only energy given out is thermal energy. This is the reason we put in our hypothesis that a When it hits the ground, the bottom of the ball becomes flat against the floor. concur, which was catching the small balls. The bounce of the ball is a major factor in the game of tennis. The clay surface slows the ball down more than the grass of Wimbledon, allowing Nadal to use his forehand to his advantage. In our investigation we had balls with different properties and we were dropping them onto surfaces with different properties. Concrete will help bounce a ball the highest as it's hard and Tennis cannot be played at a certain temperature; however, 70-90 degrees Fahrenheit is ideal. I plan to collect at least ten results as this will make the conclusion and graph I am able to draw from the experiment more accurate than if I had less results than ten. The average variation between results was 3cm. Once the ball hits the ground, its displacement is momentarily zero. 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 felt helps to create spin on the ball when it is hit with a racket. The drag force increases as the ball goes faster. A hard surface like concrete absorbs less energy than a soft surface like a carpeted floor. The higher the ball goes, the more GPE it ends up with. If the coefficient to restitution = 0.7, a ball dropping from h, in a vacuum would reach the height of 0.7 h, As velocity increases air resistance increases in proportion to the square of the velocity. Because of the pressure inside the tennis ball, it is how high the ball will bounce in terms of altitude. faced. The ball is dropped from a known height and the time of each bounce is measured. According to our background research, a The ball feels softer on the hand, but much harder on impact, resulting in a very different type of tennis. Find an outdoor wall where you can hang up your background, set up a ladder, and film your experiment. the higher it popped up into the air. (Doherty, 1991). We did this by bouncing different types of balls I will drop the ball 3 Athletic and cardio abilities are becoming a bigger factor each season, but some players remain hard courts experts. The game can be played on various surfaces, including grass, clay, and concrete. Balls are not round. catcher to catch the balls. Keep a close eye on the ball, and instruct Phlebas to do the same. This still took us time and we still couldn't catch the Reverse Engineering: Ball Bounce Experiment Hands-on Activity Reverse Engineering: Ball Bounce Experiment (2 Ratings) Click here to rate Quick Look Partial design process Grade Level: 4 (3 - 5) Time Required: 1 hours 45 minutes (2 or 3 class periods) Group Size: 3 Subject Areas: Students investigate balls and their bounce copyright Summary 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. Although catching small balls was an issue, we solved it by getting our better half the results (concrete), we were incorrect about the basketball. 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. Click the "Experiment" button to find out! 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. 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. ball bounced 6 inches. Then draw a line to connect the dots.

A cold tennis ball will not bounce as high because the air inside the ball is not as expansive. was blowing in, so that if the balls were blown away, they would come straight to 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 . 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. 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. Working out the variation in results shows how accurate the experiment was. The more energy absorbed by the surface, the less that remains in the ball for it to bounce. External factors, i.e. Drop (do not throw) the ball from a carefully measured height using the meter stick. 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. The surface onto which the ball is dropped upon will be kept the same. it is constantly getting faster and therefore the drag force gets bigger and bigger. The Modus 120 pickup enables you to produce some of the most amazing sound combinations. The ball has reached its terminal velocity and cannot fall any faster (unless dropped in a vacuum). Why does a tennis ball bounce higher on concrete? What material makes a ball bounce higher? 1. us. Note whether the ball and surface showed more of an elastic or inelastic collision. 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. 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 temperature of a tennis ball can affect its bounce height. It should be tall enough to hang up behind your ladder, about 5feet tall. As the ball hits the blades of grass, they bend and don't provide as much upward rebound. 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. This was added onto another issue we had to The pressure difference between hot and cold temperatures is significant. However the conditions were kept the same for each drop of the ball. 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. "Under Pressure: Ball Bouncing Dynamics.". from the ball, therefore causing it to bounce higher than it normally would on dirt 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. 30% of the energy that the ball hits the floor wit is lost. The strength of Nadals forehand is what makes him so good on clay. Aim: to find out which surface bounces a ball the highest. This will be repeated five times, possibly more (for accuracy), for each height and the top and bottom results will be discounted. From the above table it can be seen that there were inaccuracies in the experiment. 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. As the ball falls it hits against air particles. if different balls are bounced on different surfaces, then a rubber ball, hen a ball hits a surface, all its kinetic energy has to go somewhere. B. - Measuring tape x This is called the relative speed. , v is greater therefore KE is greater by a larger amount). Height will be the variable that we will vary. The higher h1, the faster the velocity that the ball reaches. The aim of the experiment my partner and I performed was to find out which By using a simple tennis ball and a thermometer, kids can measure the temperature of the ball and see how it changes as the game goes on. The energy that the ball hits the floor with is kinetic energy. As a result, the balls bounce decreases as pressure decreases. For multiple bounces, it's just like dropping the ball again from a reduced height. When printing this document, you may NOT modify it in any way. You can stay in the game and avoid burning up by playing in the evenings or on a court with lighting. Ball trial 1 trail 2 trial 3 average Different Surfaces Equal Different Bounce Balls get distorted when they bounce. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. The higher the air pressure the more air particles per cubic meter. This causes thermal energy to be given off. There are more than 160 different types of tennis surfaces. 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. Fully pump up the basketball and check the pressure with the pressure gauge. 70% is retained. 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. KE = 1/2mv where m = mass and v = velocity, 1/2mv = mhg - thermal energy (lost as a result of drag). It will be vinyl tiling. The ball shoots back up after being slowed down. 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. The ultimate answer was that a basketball 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. The maximum and minimum results were included when working out the variation between results however, seeing as the maximum and minimum results were produced by the experiment and are therefore part of the variation between results produced by the experiment.
