Does the weather make a difference? - Rubber ball x It is usual in science to plot the dependent variable on the vertical axis (y-axis) of the graph and the independent variable on the horizontal axis (x-axis) of the graph. 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. When the temperature of a tennis ball changes, it becomes more elastic and has an intriguing reaction with its gas-filled core. The more energy that the ball possessed before being dropped, the more energy was converted into KE while the ball fell. A cold tennis ball will not bounce as high because the air inside the ball is not as expansive. 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. Warmer balls bounce better than cold ones. The reason balls bounce is quite advanced science. , v is greater therefore KE is greater by a larger amount). Therefore the coefficient to restitution = 0.7. If the coefficient to restitution = 0.7, a ball dropping from h1in a vacuum would reach the height of 0.7 h1 after bouncing. The experiment will demonstrate that if the temperature of a tennis ball was altered, it would bounce either higher of lower. Removing the maximum and minimum results and taking an average of the middle three results also provided more accurate results. ping pong 2 cm 3 cm 2 cm 2 cm, basketball 82 cm 84 cm 80 82 1. 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. Working out the variation in results shows how accurate the experiment was. The longer it takes to stop, the higher it bounces to. Then when dropping the ball again eye level will be kept level with the blue tack thus avoiding parallax errors. Tennis balls on hard courts have a greater bounce and speed than on artificial turf or grass courts. 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. 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. will differ from the height that the ball would have reached had it been dropped in a vacuum. Which ball will bounce higher off a hard surface? Steel balls bounce higher than rubber balls. Why a ball bounces: The ball's energy is matched by the ground it hits. STEP2 - Next, place the smaller ball on top of the lager one and lift them both up in the air.. STEP3 - Drop em'!. It shows that heights were recorded that exceeded the height that the ball would have reached had it been dropped in a vacuum. h1and h2are 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. Use the pressure gauge to release some of the air pressure from the ball. Repeat the process three times with the same ball and record results. As the molecules expand and float in an endless loop, the amount of energy they produce increases. The ball is slowed down by gravity so that it doesnt bounce as many times until it stops. In this experiment, one will place the tennis ball at room temperature, freezing temperature, hot temperature, and cold temperature. Make a note of which one bounces up higher and how high they bounce! Reproduction of material from this website without written permission is strictly prohibited. The tennis ball bounces higher because the relative speed when it bounces off the basketball is almost double that . If the drag is less the ball will fall faster and is less likely to reach its terminal velocity. Such an impact compresses the ball 1.4-1.6 inches, or about 54-62% of its diameter. Cold weather causes the rubber to harden, resulting in drops in air pressure inside 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. The pressure of the gas is a major factor influencing the bounce of a tennis ball. The balls finish up with the same amount of energy and the only energy given out is thermal energy. Aim: to find out which surface bounces a ball the highest. The air in the ball expands and contracts as it is compressed. For instance result 3 from 200cm was an anomaly but was not taken into account when taking the average of the middle three. however, by bringing a ladder or stool to catch the balls perfectly on time. Here's what you need to do this experiment: Bouncy Balls - a least 6 identical balls; A measuring cup or mug for heating water in the microwave; Access to a freezer . Therefore, our hypothesis was refuted by our final results. - Paper x 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. This cookie is set by GDPR Cookie Consent plugin. Use the pressure gauge to release some of the air pressure from the ball. This will be a table tennis ball. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. Measure from the bottom of the ball. - Pencil x When printing this document, you may NOT modify it in any way. This would eliminate parallax error further. This results in faster . 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. 3. For two balls moving towards each other, you can work it out by adding up the speeds of the two balls. When the ball hits the floor and stops, that energy has to go somewhere. by Jonah Lehrer on September 8, 2011. he official rule book of tennis is 35 pages long. Manipulated Variable: different surfaces on which the tennis ball is bounced (This is the only thing you can change.) The first independent variable that will be tested. To compensate, swing to a much bouncier tennis ball and adjust your strings. Our team of volunteer scientists can help. We use cookies and those of third party providers to deliver the best possible web experience and to compile statistics. This is longer than the 5-8 ms ball bounce from a solid surface or racquet. (2020, January 12). Science Buddies Staff. Reproduction of material from this website without written permission is strictly prohibited. As a result, they move at a slower rate of speed with less energy. The Swiss like to get points over and done with in a short period of time. Measuring tape 3. 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. quicker and on time before they dropped back down. The experiment was conducted well however as the utmost efforts were brought into place to avoid parallax error and it was ensured as far as possible that factors that affected how high the ball bounced, excluding the height, were kept constant throughout the experiment. Repeat steps 1-6 with the different balls. Parallax error will be avoided by dropping the ball one time that will not be measured and placing a blob of blue tack onto the meter rule at the approximate height it bounced to. found that different surfaces absorb different amounts of energy, and the less Conclusion: Focus the students on the aim of the experiment (that is, to determine a pattern from which to make comparisons, rather . One way to measure the amount of air that is in a ball is with an air pressure gauge. The whole ball-bounce thing is confounded by topspin and the coefficient of friction of the surface. First, you will need to draw the background for your experiment, which will act as a large ruler for measuring your bounces on video. energy a surface absorbs, the more of it will remain for a ball to bounce. Therefore the height that it reaches is less high. At 3ft, the basketball bounced 20 inches, the tennis ball bounced. 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. Section II: Hypothesis. The ultimate answer was that a basketball When the temperature rises, the gas molecules within tennis balls expand and move in strange directions. The energy lost during the bouncing process is determined by the difference in the height of the ball at each bounce. Take your class outside, to an area with a smooth, flat surface. Try bouncing different kinds of balls to test this question. All rights reserved. Gather 15 to 20 tennis balls and a measuring tape. Use a uniform surface to drop the ball onto. 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. 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. Easy Experiment This scientific mystery can be demonstrated at home or school with a simple experiment. If the KE is the same as they hit the ground the energy stored in the ball as elastic potential energy will be the same also. A ball that is dropped in air however is subjected to air resistance which affects the height to which it bounces. Instead, as the ball is still always loosing GPE so long as it is still falling, all GPE is converted into thermal energy. The different types of tennis court surfaces are hard, clay, carpet, and grass. To determine how high a tennis ball will bounce when dropped from a . will start at 2m and then move down in intervals of 10cm to 10cm. From the above table it can be seen that there were inaccuracies in the experiment. Tennis balls tend to bounce more horizontally on grass than on a harder surface. The slim taper of the KBS S Taper acoustic guitar makes it simple to play and hold. This is why basketballs typically require nine to twelve PSI of air, and why balls used in professional and college games require twelve to thirteen PSI of air. The higher the air pressure the more air particles per cubic meter. Click the "Experiment" button to find out! Drag is a squared function of velocity and therefore as the ball drops drag increases a greater amount each second. Please wait while we set up your subscription TurnItIn the anti-plagiarism experts are also used by: King's College London, Newcastle University, University of Bristol, University of Cambridge, WJEC, AQA, OCR and Edexcel, Business, Companies and Organisation, Activity, Height and Weight of Pupils and other Mayfield High School investigations, Lawrence Ferlinghetti: Two Scavengers in a Truck, Two Beautiful People in a Mercedes, Moniza Alvi: Presents from my Aunts in Pakistan, Changing Materials - The Earth and its Atmosphere, Fine Art, Design Studies, Art History, Crafts, European Languages, Literature and related subjects, Linguistics, Classics and related subjects, Structures, Objectives & External Influences, Global Interdependence & Economic Transition, Acquiring, Developing & Performance Skill, Sociological Differentiation & Stratification. The ball weighs exactly 2.5g. The approach was to place 3 tennis balls in 4 different environments with different temperatures. Why do balls bounce higher on different surfaces? An average will then be taken. This means that the faster that the ball travels the larger the force of air resistance upon it. h1will start at 2m and then move down in intervals of 10cm to 10cm. The ball did not reach terminal velocity however as it did not have enough time to accelerate to its terminal velocity. Launch Related Video : The Hawk Factor.

You can also try using a hair dryer to heat the ball up. his the height of the balls bounce. [accessed August 4, 2006]. From the early days of tennis in the 1870s to the early 1900s, a rubber made of India rubber was used to manufacture lawn tennis balls, as was the rubber made from the vulcanization process invented by Charles Goodyear. METHOD: 1. Grades: Preschool and K-2. This means that KE is the same for both balls when each ball hits the ground. Try your bounce test in different weather conditions. old and new tennis balls (different surface textures/ages). 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. For a squash ball, f might be less than 0.5 or 0.25 - squash balls are not very bouncy. Why Does One Tennis Shoe Pull Your Sock Down? Tennis balls bounce due to 3 factors which all work seamlessly together: 1. Air is pumped into the ball and causes it to bounce. 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. If it bounces up less than .5 meter, then it is more inelastic. An alternative method would be the measuring person holding a video camera level with the approximate height that the ball reaches after bouncing and videoing the ball reach the top of its arc. Repeat step 5 with all of your other surfaces. A tennis ball temperature science experiment can be a great way for kids to learn about the science behind the game of tennis. Performance cookies are used to understand and analyze the key performance indexes of the website which helps in delivering a better user experience for the visitors. EQUIPMENT: 1 metre ruler 1 table tennis ball. C. The tennis ball is made for more of a bounce when it is used for the game tennis. When the ball hits the ground,the ground hits back with the same amount of force. 15 inches, and the golf ball bounced 26 inches. Do you have specific questions about your science project? Each can from the same manufacturer can be different. It was difficult to get down to the exact level of the blue tack seeing as it meant lowering your entire upper body in the short amount of time taken for the ball to hit the floor and rebound again to get your eye level from h, (where the blue tack was stuck, approximately). The 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. Will the air pressure change the bounciness of a ball? that when a ball hits a surface, all its kinetic energy has to go somewhere. As an example, on the day we performed our experiment, a strong wind was Also it will affect its bouncing properties. Also the facts that there were no anomalies and that all of the points were very close to the line of best fit show that the experiment was relatively accurate. Why does Rafael Nadal do so well on the clay? One of the hunks of information we found was changing air density, temperature. energy a surface absorbs, the more of it will remain for a ball to bounce. If the ball bounces up more than .5 meter then, it is more elastic. This did not happen in my experiment however. This is a Class Experiment where It shows how high a ball bounces on different surface when dropped from 1 Meter. is well-inflated and made of rubber which would give it more kinetic energy and In this experiment you will use a ball filled with air. Place one of the tennis balls in the freezer for 20 mins 2. Then draw a line to connect the dots. Place the tape measurer against the edge of a wall using the bluetack 3. The equipment necessary to generate these conditions was not available and as a result the results obtained were not one hundred percent accurate. 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. For any other use, please contact Science Buddies. Balls bounce in ways that are affected by gravity. Although we were correct about This will be called the average of the middle three repeats. If the mass of the ball is heavier the weight is heavier (weight = mg) and downward force acting upon the ball is greater as well. The height of the ball at each bounce is then calculated. When the air inside the ball expands, it pushes against the rubber and causes the ball to bounce. The temperature of a tennis ball can affect its bounce height. (Doherty, 1991). Tennis balls bounce differently in the high altitude and at sea. Does height make a difference? 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. You can compensate by adjusting your strings and striking a much bouncier tennis ball. Apparatus:Clamp stand, meter rule 2, table tennis ball, desk. You also have the option to opt-out of these cookies. With this information, we A ball bounces in an arc, so measure the height at the top of the arc of the first bounce. These cookies track visitors across websites and collect information to provide customized ads. Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. This means that if a heavier ball is to be used then it will need to be dropped from higher to reach its terminal velocity. Keep releasing pressure and repeating the experiment until the ball no longer bounces. troubles my partner and I had during our experiment along with the problems we 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. Does it slope up or down? This will mean that I will have to have the interval between the different heights from which the ball is dropped from less than 20cm, probably at 10cm. The ball has reached its terminal velocity and cannot fall any faster (unless dropped in a vacuum). Note whether the ball and surface showed more of an elastic or inelastic collision. Answer (1 of 2): Some surfaces absorb more energy than others do. When the temperature drops, gas molecules in close proximity. chose balls and surfaces with different hardnesses, textures and compositions in Ball trial 1 trail 2 trial 3 average The impact duration was between 65 and 71 ms. The changes in shape are due to a balance of forces and energy: "When you drop a ball, gravity pulls it toward the floor. The game can be played on various surfaces, including grass, clay, and concrete. It might be a good idea for students to experiment with a variety of balls to determine which one is most effective. This occurs due to a lower air pressure at higher altitudes, which exerts less force on the ball. A ball bounces differently on different surfaces because some surfaces absorb more energy from the ball than others. Then when dropping the ball again eye level was kept level with the blue tack. They are typically softer, allowing them to give them a little more space and make them easier to hit. Air pressure will affect the balls fall slightly as the concentration of air particles per cubic meter varies with air pressure. 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.

Therefore of the GPE that the ball possessed at the beginning some energy is given off as thermal energy. Then when dropping the ball again eye level was kept level with the blue tack. A cold ball typically has less bounce than a warm ball. We This is impossible. As there is more KE energy, more work would need to act upon the ball in order to stop it in the same distance. 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. The temperature of the tennis ball has an impact on its bounce. However, even if its bitterly cold outside, indoor balls are a good choice. It shows that heights were recorded that exceeded the height that the ball would have reached had it been dropped in a vacuum. The more energy absorbed by the surface, the less that remains in the ball for it to bounce. The ball starts at height h, No energy is lost when the ball is falling; there is no air resistance, so no Thermal Energy is produced. Find a clear space to work in. Science Buddies Staff. 70% is retained. Then they would be dropped from a table, and the height would be measured. There are more than 160 different types of tennis surfaces. What do you think this means about your results? 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. 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. Therefore the ball goes higher. Height will be the variable that we will vary. Hypothesis: if different balls are bounced on different surfaces, then a rubber ball . Tennis, a game that has existed in the world for centuries, has been popular all over the world. 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. 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. When it hits the ground, the bottom of the ball becomes flat against the floor. All rights reserved. Length of Lesson: 30 - 45 minutes. It should be on a smooth cement surface for optimal ball bouncing. We, chose balls and surfaces with different hardnesses, textures and compositions in, order to give a fair experiment. Not only does a ball distort its shape--so does the surface on which the 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). Use two people to measure the results; one person to drop the ball and one to measure the height to which it reaches after bouncing. This causes thermal energy to be given off. were able to construct a successful experiment. 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. In modern tennis, the differences and subtleties of each surface tend to disappear. 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. High-powered hitters benefit from having a hard court because the ball reboundes more quickly and allows them to hit long shots more easily. hard ball made of rubber should bounce the highest on a concrete surface, which Anyone, regardless of age or ability, can take part in tennis on a court with a ball. 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. How Much Do Air Jordan Tennis Shoes Cost? order to give a fair experiment. 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. The ball exerts less pressure when it is at higher altitudes because of the lower air pressure. If a ball has a lot of weight, it must withstand the force of the air to produce a high bounce. As there is more KE, more energy is converted into elastic potential energy, As there is more elastic potential energy, more energy is converted back into KE energy. The surface onto which the ball is dropped upon will be kept the same. - Sticky tape - 1 roll. Most of the points on grass are very short. This is because it is easiest as the figure read of the meter rule is the result. Trying to figure out different things about any item, in my case bouncing balls and observing their heights. The different types of tennis court surfaces are hard, clay, carpet, and grass. 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. If you like this project, you might enjoy exploring these related careers: You can find this page online at: https://www.sciencebuddies.org/science-fair-projects/project-ideas/Phys_p039/physics/balls-bouncing-off-of-surfaces. As the ball hits the blades of grass, they bend and don't provide as much upward rebound. This is due to two factors. As a result, the balls bounce decreases as pressure decreases. Its not just a game for the wealthy; its also a game for everyone. were able to construct a successful experiment. For our wind situation, one of us stood in the direction that the breeze It is a firm rectangular surface with a low net stretched across the centre. Take a ball and place it on the 150 cm line and drop it. 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). How can you measure the height a ball bounces? What was the outcome? September 28, 2022 by George Jackson. Please enter a search term in the text box. - tennis ball x Tennis cannot be played at a certain temperature; however, 70-90 degrees Fahrenheit is ideal. Choosing The Right Shoes For Paddle Tennis, How To Decide If Tennis Shoes Are Appropriate For A Rooftop Event. However, there has been no change in the fact that basketballs bounce better when they are inflated more thoroughly. Write your measurements down. A decrease in h1, assuming g and m stay constant, results in a decrease in m g h1which results in a decrease in GPE. 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. Therefore, harder surfaces will ultimately bounce a ball higher. It provided me with five repeats so that the maximum and minimum results could be discounted and a reliable average could be taken.
