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. The energy goes into deforming the ball-- from its original round shape to a squashed shape. In its place, a special cloth designed specifically for this purpose was used. Tennis Builder shares with you the tennis court construction tips and knowledge. Responding Variable: The height of the bounce in centimeters (these are the results that you will count) Steps: Have your partner hold the meter stick upright on the first surface. Copyright 2002-2023 Science Buddies. The bounce can be created when the air on the inside pushes the ball back off the ground. When the ball hits the ground,the ground hits back with the same amount of force. 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. C. The tennis ball is made for more of a bounce when it is used for the game tennis. 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. The difference between the predicted height and the actual height will provide evidence as to how air resistance affects the flight of the ball. Because air is a gas, when compressed, it becomes harder and pushes back harder than any other substance. his the height of the balls bounce. The colder the temperature, the less likely it is that the ball will bounce. I also Data from the most recent bounces per temperature or the third trial is used to create the graph. Science Buddies Staff. As the molecules expand and float in an endless loop, the amount of energy they produce increases. Repeat step 5 with all of your other surfaces. In this manner, you apply heat shrink to your head and heat it up until the shrink shrinks. Different courts are better suited to each players style. The mass of the ball will affect the height the ball bounces to because it affects the balls starting energy. What factors affect the bounce height of a ball? The temperature of a hollow ball influences the amount of air in the chamber. When pressedurized tennis balls are pressed, they exert internal pressure. I used a Flexible measuring tape to measure what the height was. The results of the experiment were obtained with a method that ensured that every drop was under similar conditions which ensured a fair test. Focus. Conclusion: Hypothesis: if different balls are bounced on different surfaces, then a rubber ball For the most part, the document is a case study in compulsive precision. The same square of tiling will be used throughout the experiment so that inconsistencies between different floor tiles do not affect results. Hypothesis. in the execution of our experiment. measured the heights. 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. 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. The cookie is used to store the user consent for the cookies in the category "Analytics". Gravel got bounced on the least, 1 time . It is also necessary to warm a ball, because the energy inside it is released. 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. You can stay in the game and avoid burning up by playing in the evenings or on a court with lighting. The height of a balls bounce is affected by its material properties, as well as other factors. Results are presented for a tennis ball, a . More thermal energy is also produced. Necessary cookies are absolutely essential for the website to function properly. Do different kinds of balls bounce differently? How Much Do Air Jordan Tennis Shoes Cost? Use a uniform surface to drop the ball onto. This is because the experiment is a very short and simple one to carry out and if conducted efficiently can be completed easily within the time span allowed for collecting evidence. Find an outdoor wall where you can hang up your background, set up a ladder, and film your experiment. Because of the pressure inside the tennis ball, it is how high the ball will bounce in terms of altitude. Experiment 2 is for testing the effect of air pressure. Why do golf balls bounce so high on concrete? For a falling object the Coefficient to restitution (C, ) is equal to the velocity squared as the object is travelling at as it leaves the floor (v, ) divided by the velocity squared as it hits the floor (v, If a ball is dropped in a vacuum. Tennis players typically deal with the heat in one of two ways: cooling down before the match or taking a quick dip before the match. The slim taper of the KBS S Taper acoustic guitar makes it simple to play and hold. 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 grass does not provide as much upward rebound when the ball hits it. 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. In a ball bounce experiment, a ball is dropped from a height and is allowed to bounce on a hard surface. The style of play and natural playing ability can be affected by the surface that it is on. Record the new pressure reading in your data table and repeat steps 4 and 5. This means it will be travelling the same speed when it hits the ground. 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. The reliability of our experiment wasn't so strong. 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. Few independent variables will be changed, so the investigation is easy to manage, and the data is easier to process. 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. You can also try using a hair dryer to heat the ball up. 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. Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features. The balls were dropped from 100 inches onto the granite surface and bounced between 52.93 and 58.43 inches. Write your measurements down. Drop (do not throw) the ball from a carefully measured height using the meter stick. The air in the ball expands and contracts as it is compressed. Aim:To find out what affects the height to which a ball bounces. Therefore, harder surfaces will ultimately bounce a ball higher. Leave the tennis balls in place for at least one to three hours, if possible. Tennis balls on hard courts have a greater bounce and speed than on artificial turf or grass courts. h2= The distance between the bottom of the ball at the top of its arc after bouncing and the ground. - Four surfaces (carpet, rough concrete, dirt and smooth concrete). from the ball, therefore causing it to bounce higher than it normally would on dirt A cold tennis ball bounces lower than a warm one. 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. Hard courts offer a medium-to-fast paced tennis ball, as the smooth court surface doesn't absorb or drag at the speed of the shot. (2020, January 12). This can be explained by two factors. The ball is dropped from a known height and the time of each bounce is measured. use four meter sticks and go right the way up to four meters. 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. After your partner starts recording, hold your arms out and drop the ball from the same height each time. But what makes a ball bounce? A tennis balls trajectory is determined by its temperature. Record the new pressure reading in your data table and repeat steps 4 and 5. The ball shoots back up after being slowed down. Does a tennis ball bounce differently on different surfaces? Warm up the ball before it is used to increase its bounce. In air considerations have to be taken into account such as air resistance but even so the rough height to which it will bounce to can be predicted before dropping the ball. Let the ball bounce until it stops, and then stop recording. - Basketball x on different types of surfaces, then recorded the height of the bounce. 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. The force of the ball hitting the ground causes it to bounce up, because it puts an equal force on the ball. If you play in hot weather, your balls may bounce significantly more. A decrease in bounce is caused by a colder temperature. A ball that is dropped in air however is subjected to air resistance which affects the height to which it bounces. The higher the air pressure the more air particles per cubic meter. Bouncing Ball Investigation This is an experiment to investigate bouncing balls and how they behave in different situations. Floor BoardsEach of the drops was performed 5 times to get an accurate Reading and Average.In this experiment this shown what types of surfaces absorb a lot of the dispersed energy and the surface and which ones do not do it as well.This was done on iMovie and took 2 Hours to Create.So Please Enjoy! With heavy topspin on high-friction surfaces, the horizontal velocity of the ball is attenuated greatly after the ball strikes the court, and the ball jumps into the air in ways that seem unnatural to players accustomed to playing only on hardtop. 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 . To find out what affects the height to which a ball bounces. Place the tape measurer against the edge of a wall using the bluetack 3. In this experiment you will use a ball filled with air. Reproduction of material from this website without written permission is strictly prohibited. Copyright 2023 StudeerSnel B.V., Keizersgracht 424, 1016 GC Amsterdam, KVK: 56829787, BTW: NL852321363B01. You can even play tennis outside in any weather. Balls are not round. Why a ball bounces: The ball's energy is matched by the ground it hits. - tennis ball x = The distance between the bottom of the ball before it is dropped and the ground. 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. This will hopefully discount any anomalies automatically and leave us with three accurate and reliable results. After the ball reaches terminal velocity, no more GPE is converted into KE is the ball cannot get any faster. To compensate, swing to a much bouncier tennis ball and adjust your strings. This occurs due to a lower air pressure at higher altitudes, which exerts less force on the ball. These inaccuracies could have been caused by external factors or parallax error even though efforts were made to avoid parallax error occurring - by dropping the ball one time that was not measured and placing a blob of blue tack onto the meter rule at the approximate height it bounced to. 3. an incorrect and unreliable result. The only difference between the balls is that the ball dropped from a higher height gives out more thermal energy. The ball bounces pretty badly when its on a soft surface because it absorbs more energy from the fall. will start at 2m and then move down in intervals of 10cm to 10cm. hard ball made of rubber should bounce the highest on a concrete surface, which 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. Science Buddies: Pilobolus Spore Sac Launch. Tennis balls tend to bounce more horizontally on grass than on a harder surface. the "bouncing balls" experiment. A lot of The balls dropped from 75 centimeters will bounce higher than those dropped from 50 centimeters, and the balls in the 50 centimeter trials will bounce higher than those in the 25 centimeter trials. When the ball is pulled toward the ground, gravity slows it down so that it doesn't bounce as many times. The effect of surface on the bounce height of a tennis ball. - Rubber ball x 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. It will not bounce to high if it is heavy. 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. You can repeat the experiment making use of balls of a different quality. Let the ball bounce until it stops, and then stop recording. Tennis balls are more likely to bounce on grass. Why do balls bounce higher on different surfaces? Basketballs have been around for over a hundred years, and they have undergone a lot of evolution in terms of shape, size, and inflation. Then when it bounces up, it returns to its original shape. 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. This would allow the actual coefficient to restitution to be calculated. The ball moves upwards, reaching stage 1, i.e., maximum height, and its velocity is momentarily zero. Chemistry: The Central Science (Theodore E. Brown; H. Eugene H LeMay; Bruce E. Bursten; Catherine Murphy; Patrick Woodward), Psychology (David G. Myers; C. Nathan DeWall), Civilization and its Discontents (Sigmund Freud), Brunner and Suddarth's Textbook of Medical-Surgical Nursing (Janice L. Hinkle; Kerry H. Cheever), Principles of Environmental Science (William P. Cunningham; Mary Ann Cunningham), Business Law: Text and Cases (Kenneth W. Clarkson; Roger LeRoy Miller; Frank B. It is important to let the ball fall out of your hands, and not to push it down with your hands, wrists, or arms. discovered that there is a handful of information that would assist my partner and I This applies to a ball falling in a vacuum. old and new tennis balls (different surface textures/ages). I used a Flexible measuring tape to measure. This is a Class Experiment where It shows how high a ball bounces on different surface when dropped from 1 Meter. 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. 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 ball bounces in an arc, so measure the height at the top of the arc of the first bounce. Five repeats were done as it was deemed that an average of the middle three was reasonably accurate. 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. EQUIPMENT: 1 metre ruler 1 table tennis ball. Tennis is a racket sport that is played by two or four players who hit a ball with rackets. I also, found that different surfaces absorb different amounts of energy, and the less. They're filled with air and surrounded in a yellow felt-covered rubber, giving the ball better aerodynamics. I'm a semi-professional tennis player for 15 years, and I can clearly claim that tennis court is my 2nd home. Make a note of which one bounces up higher and how high they bounce! This causes thermal energy to be given off. This is impossible. As CR = h2/ h1it follows the gradient of the graph change in h2/ change in h1= CR. We could have improved this STEP4 - Watch as the smaller ball flies off into the air! It shows that heights were recorded that exceeded the height that the ball would have reached had it been dropped in a vacuum. Not By clicking Accept All, you consent to the use of ALL the cookies. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. Repeat the process three times with the same ball and record results. 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. What material makes a ball bounce higher? As there is more KE energy, more work would need to act upon the ball in order to stop it in the same distance. Therefore the height that it reaches is less high.
