On a grass tennis court, e y varies from about 0.6 to 0.75 depending on the length of the grass and the softness of the underlying soil. Increased energy and movement results in a bounce. There are more than 160 different types of tennis surfaces. But what makes a ball bounce? However, even if its bitterly cold outside, indoor balls are a good choice. Place the tape measurer against the edge of a wall using the bluetack 3. If you are looking for a challenging sport, tennis is an excellent choice for the winter months. The temperature of a tennis ball greatly affects how high it bounces. 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. It will not bounce to high if it is heavy. Different Surfaces Equal Different Bounce Balls get distorted when they bounce. bounces the highest on smooth concrete. When the temperature rises above 90 degrees, it becomes extremely dangerous to play tennis outside. half the results (concrete), we were incorrect about the basketball. What factors affect the bounce height of a ball? 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. experiment. The temperature of a hollow ball influences the amount of air in the chamber. As a result, the balls bounce decreases as pressure decreases. More thermal energy is also produced. Also it shows inaccuracies in the experiment as it shows that heights were recorded that exceeded the height that the ball would have reached had it been dropped in a vacuum. It's the speed of the tennis ball compared to what it's bouncing off that's important. How does the material of a ball affect its bounce? It should be on a smooth cement surface for optimal ball bouncing. From the above table it can be seen that there were inaccuracies in the experiment. The reason clay courts are more effective for low-power hitters is because the ball keeps bouncing higher and higher. Some balls to try are: soccer, basketball, volleyball, golf, tennis, or handball. was blowing in, so that if the balls were blown away, they would come straight to 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. If you're playing under 68 degrees, it's a good idea to make sure the ball doesn't bounce too much. This results in faster . 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 temperature of the tennis ball has an impact on its bounce. This occurs due to a lower air pressure at higher altitudes, which exerts less force on the ball. Use the pressure gauge to release some of the air pressure from the ball. We use cookies and those of third party providers to deliver the best possible web experience and to compile statistics. 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. KE = 1/2mv where m = mass and v = velocity, 1/2mv = mhg - thermal energy (lost as a result of drag). The same square of tiling will be used throughout the experiment so that inconsistencies between different floor tiles do not affect results. As the ball hits the blades of grass, they bend and don't provide as much upward rebound. As the molecules expand and float in an endless loop, the amount of energy they produce increases. It does not store any personal data. - Rubber ball x Tennis balls bounce due to 3 factors which all work seamlessly together: 1. 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 different types of tennis court surfaces are hard, clay, carpet, and grass. ping pong 2 cm 3 cm 2 cm 2 cm, basketball 82 cm 84 cm 80 82 To get started, all you'll need are two balls of different sizes - we recommend something like a basketball and a tennis ball. Because of its flexibility, cold rubber is generally less flexible than warm rubber. Why does Rafael Nadal do so well on the clay? 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. Push it against the measuring tape, careful to keep it at the same height. 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. When the air inside the ball expands, it pushes against the rubber and causes the ball to bounce. to find out which surface bounces a ball the highest. A tennis ball is made of rubber and is covered with felt. Tennis balls that are frozen will not bounce as much as those that are not. 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. Balls are not round. Now, take your video and watch it to gather your data. The more KE that the ball possessed as it hit the floor, the more that was transferred into elastic potential energy and back into KE. Record the new pressure reading in your data table and repeat steps 4 and 5. (Doherty, 1991). A hard surface, such as concrete, absorbs less energy compared with a soft surface, such as a carpeted floor. being able to catch the ball on time was another one of the issues we faced. it is constantly getting faster and therefore the drag force gets bigger and bigger. The energy goes into deforming the ball-- from its original round shape to a squashed shape. This means that the higher h. will differ from the height that the ball would have reached had it been dropped 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. Although we were correct about Try comparing a hot day to a cold day. Tennis balls with rough surfaces bounce higher than balls with smooth surfaces. From this I am able to determine that the experiment was very accurate. Air resistance exists but does not affect the velocity of the ball significantly. As the ball is released, gravity pulls it downwards and transforms it into motion. This cookie is set by GDPR Cookie Consent plugin. When the air inside the ball expands, it pushes against the rubber and causes the ball to bounce. Although catching small balls was an issue, we solved it by getting our better The ball weighs exactly 2.5g. Why Tennis Balls Bounce. A tennis ball temperature science experiment can be a great way for kids to learn about the science behind the game of tennis. For multiple bounces, it's just like dropping the ball again from a reduced height. Focus. Why do marbles bounce so high? To a wider range of results i.e. Record the new pressure reading in your data table and repeat steps 4 and 5. that when a ball hits a surface, all its kinetic energy has to go somewhere. Then when it bounces up, it returns to its original shape. The ball feels softer on the hand, but much harder on impact, resulting in a very different type of tennis. Why do golf balls bounce so high on concrete? This means that the higher h1the more h2will differ from the height that the ball would have reached had it been dropped in a vacuum. 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. Watch the video of the dropping tennis ball. 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 Launch Related Video : The Hawk Factor. This is because it is the easiest and quickest variable to alter. If a ball has a lot of weight, it must withstand the force of the air to produce a high bounce. This will be a table tennis ball. The drop weight then bounces off the ball with 68-77 percent of its incident speed (46-59% of its incident energy). External factors, i.e. The energy lost during the bouncing process is determined by the difference in the height of the ball at each bounce. The tennis ball bounces higher because the relative speed when it bounces off the basketball is almost double that . This cookie is set by GDPR Cookie Consent plugin. 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. Such an impact compresses the ball 1.4-1.6 inches, or about 54-62% of its diameter. Air resistance exists but does not affect the velocity of the ball significantly. Acrylic-topped, this surface offers the most consistent ball bounce of all the outdoor tennis courts. However when the ball is dropped from a relatively low height, drag 0. This is impossible. highest on hard, smooth surfaces. 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. Science Buddies Staff. or carpet. These both support my prediction and show that my prediction was correct. 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. This still took us time and we still couldn't catch the Hypothesis: if different balls are bounced on different surfaces, then a rubber ball The clay surface slows the ball down more than the grass of Wimbledon, allowing Nadal to use his forehand to his advantage. The bouncing of a tennis ball on a tennis court surface is analysed by making several simplifying assumptions about the physics of the interaction. energy a surface absorbs, the more of it will remain for a ball to bounce. This means that the faster that the ball travels the larger the force of air resistance upon it. A lot of 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. As the ball falls it hits against air particles. STEP4 - Watch as the smaller ball flies off into the air! Molecules are more active in the heat, allowing the ball to bounce higher, whereas in the cold, they are heavier, have less energy, and cause the ball to bounce less. Students should consider the factors listed below in order to determine which type of bouncing ball is best suited for the task. 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. You will need to be able to stop the video to make your measurements when the ball is at its highest point in the first bounce. Write each measurement in the data table. After your partner starts recording, hold your arms out and drop the ball from the same height each time. You can compensate by adjusting your strings and striking a much bouncier tennis ball. What do you think this means about your results? If we in the execution of our experiment. - Basketball x Measuring tape 3. The procedure allowed me to observe the affects of the height from which a table tennis ball was dropped from upon the height to which it bounced. Which surface bounces a ball the highest? Friday - 25/04/14 Cold weather causes the rubber to harden, resulting in drops in air pressure inside the ball. Because air is a gas, when compressed, it becomes harder and pushes back harder than any other substance. Also it will affect its bouncing properties. The cookies is used to store the user consent for the cookies in the category "Necessary". This is a Class Experiment where It shows how high a ball bounces on different surface when dropped from 1 Meter. However the conditions were kept the same for each drop of the ball. Then when dropping the ball again eye level was kept level with the blue tack. 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 . Carpet2. 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). As CR = h2/ h1it follows the gradient of the graph change in h2/ change in h1= CR. As the temperature rises, the gas molecules in the tennis ball expand. This is because as the ball goes faster it passes through a greater volume of air each second. As it did so the downward force was partially balanced out by the upwards force of drag, increasingly so the closer the ball got to its terminal velocity. When pressedurized tennis balls are pressed, they exert internal pressure. The cookie is set by the GDPR Cookie Consent plugin and is used to store whether or not user has consented to the use of cookies. As there is more GPE more energy is converted into KE (The ball is going faster, KE=1/2mv. 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. Bouncing Ball Investigation This is an experiment to investigate bouncing balls and how they behave in different situations. The cookie is used to store the user consent for the cookies in the category "Performance". Copyright 2002-2023 Science Buddies. 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. Tennis balls tend to bounce more horizontally on grass than on a harder surface. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. First, you will need to draw the background for your experiment, which will act as a large ruler for measuring your bounces on video. Repeat steps 1-6 with the different balls. Working out the variation in results shows how accurate the experiment was. After the ball reaches terminal velocity, no more GPE is converted into KE is the ball cannot get any faster. Copyright 2023 StudeerSnel B.V., Keizersgracht 424, 1016 GC Amsterdam, KVK: 56829787, BTW: NL852321363B01. - tennis ball x When it reaches Earth, it collides head-on with an . For instance, you can use old balls for the second round of the experiment compared to new balls. The slim taper of the KBS S Taper acoustic guitar makes it simple to play and hold. An investigation into how they impact play on the court. This is impossible. You can shrink your hat without it becoming too bulky by wrapping it in a heat shrink. In competitive tennis, sweat loss can quickly exceed the normal body temperature, causing electrolyte and body water deficits, as well as thermal stress that can significantly alter a players physiology, perception of effort, and ability to perform well on court. will differ from the height that the ball would have reached had it been dropped in a vacuum. Conclusion: Aim: to find out which surface bounces a ball the highest. Air is pumped into the ball and causes it to bounce. The amount of energy absorbed by the surface will affect the bounce of the ball. The balls finish up with the same amount of energy and the only energy given out is thermal energy. The reliability of our experiment wasn't so strong. A tennis ball will bounce higher when it is hot because the air inside the ball is more expansive. "Under Pressure: Ball Bouncing Dynamics.". Not 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. Tiles3. rubber ball would bounce the highest on concrete. This therefore provides accurate and reliable results. Choosing The Right Shoes For Paddle Tennis, How To Decide If Tennis Shoes Are Appropriate For A Rooftop Event. Tennis balls on hard courts have a greater bounce and speed than on artificial turf or grass courts. If it bounces up less than .5 meter, then it is more inelastic. 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. 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. 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. Taking an average of several results creates a measurement in the middle of the variation created by the experiment, which is the result that is closest to the height that would be recorded for the balls bounce if it were measured in an experiment that was totally accurate. . 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. was proven correct after our experiment. 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. This is the reason we put in our hypothesis that a Warmer balls bounce better than cold ones. Best hard court players of all time Belowis the graph of h1against h2. It should be tall enough to hang up behind your ladder, about 5feet tall. Therefore the height that it reaches is less high. 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. Hypothesis. This means that the faster that the ball travels the larger the force of air resistance upon it. Therefore, On the cardboard, mark the starting point, the point where the marble strikes the wood, and a point along the marble's path as it rolls away from the wood. troubles my partner and I had during our experiment along with the problems we Fully pump up the basketball and check the pressure with the pressure gauge. 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. 2. 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. 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. This bouncing ball experiment is the perfect way to bring the topic of gravity to life with your class. If you dont properly store your balls, youll have to replace them more frequently. Hypothesis If I increase the height from which a ball is dropped then the bounce height will increase because it will increase the speed and create a larger impact causing the ball to bounce higher then dropping it from a lower height. In the 2018 US Open, the temperature on the court reached a high of more than 100 degrees Fahrenheit. Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. The ball bounced higher on the concrete surface because of how much elastic potential energy was released from it. 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. Reproduction of material from this website without written permission is strictly prohibited. Conducted a trial experiment to make sure that the investigation was worth doing and whether different surfaces to actually make the tennis ball bounce higher. Decide on a height you want to drop the balls from . 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 . 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. Therefore the coefficient to restitution = 0.7. [accessed August 4, 2006]. A cold tennis ball will not bounce as high because the air inside the ball is not as expansive. 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. composition so it was higher up in the air, with this we were able to catch the balls I used a Flexible measuring tape to measure what the height was. . From this it can be seen that using the average of the middle three results is more accurate than using the average of all five, as it automatically discounts most anomalies. In this manner, you apply heat shrink to your head and heat it up until the shrink shrinks. Drop (do not throw) the ball from a carefully measured height using the meter stick. 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. September 28, 2022 by George Jackson. As the ball hits the floor with less KE than it would have done if it had been dropped in a vacuum it follows that less energy is converted into elastic potential energy and back into KE again. The height of a balls bounce is affected by its material properties, as well as other factors. A glass ball will bounce higher than a rubber ball if it doesnt break. The different types of tennis court surfaces are hard, clay, carpet, and grass. 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. Therefore any change to the height from which the ball starts with affects the height to which it bounces to. order to give a fair experiment. Averages are more reliable than using one result as they take into account variation between results. The balls bounced higher on the concrete The grass does not provide as much upward rebound when the ball hits it. and tries to catch the balls on time. "Balls Bouncing Off of Surfaces.". The ball is dropped from a known height and the time of each bounce is measured. 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 ball gains energy of motion, known as kinetic energy. An increase in h1, assuming g and m stay constant, results in an increase in m g h1 which results in an increase in GPE. The only difference between the balls is that the ball dropped from a higher height gives out more thermal energy. When a bouncing ball falls, it initially gains speed or kinetic energythe energy of motion. It shows that heights were recorded that exceeded the height that the ball would have reached had it been dropped in a vacuum. A similar length stick, marked in 5-10cm bands of colour. Take a ball and place it on the 150 cm line and drop it. changing air density, temperature. This causes thermal energy to be given off. This experiment requires a ball that will bounce and a meter stick or other measuring device. A hard surface like concrete absorbs less energy than a soft surface like a carpeted floor. Abstract and Figures. The Racquet Sports Industry's website states that, like human fingerprints, no two balls seem to be alike, and each has slightly different bouncing ability. The difference between the predicted height and the actual height will provide evidence as to how air resistance affects the flight of the ball. measured the heights. Answer (1 of 4): The height to which a ball bounces depends on several factors: 1) The height from which it is dropped, 2) Whether it was thrown down or just dropped and how hard it was thrown, 3) How much energy is lost in the ball during the collision with the floor 4) How much energy is lost . quicker and on time before they dropped back down. Internal air pressure is critical to the bounce of most tennis balls. 15 inches, and the golf ball bounced 26 inches. carpet, tennis 57 cm 56 cm 61 cm 58 cm When a ball drops in air there is air resistance to which the ball loses energy in the form of thermal energy. Few independent variables will be changed, so the investigation is easy to manage, and the data is easier to process. The same surface can be used to play both doubles and singles matches. The equipment necessary to generate these conditions was not available and as a result the results obtained were not one hundred percent accurate. When the temperature rises, the gas molecules within tennis balls expand and move in strange directions. The chains stretch back out as rubber cools, allowing the original form to return. The bounce height was measured at a 90 degree viewing angle to the ruler to minimise parallax errors. - Ping pong ball x 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. Observe the height of the 1st rebound height of the tennis ball. EQUIPMENT: 1 metre ruler 1 table tennis ball. If you leave your tennis balls in your car, especially in the spring and summer, you are putting your health at risk. Science Buddies Staff. At 2ft, the basketball bounced 15 inches, the tennis ball bounced 12 inches, and the golf. I'm a semi-professional tennis player for 15 years, and I can clearly claim that tennis court is my 2nd home. - Measuring tape x The movement of the air causes the ball to bounce back off the . At 3ft, the basketball bounced 20 inches, the tennis ball bounced. . METHOD: 1. As an Amazon Associate I earn from qualifying purchases.Privacy Policy | Affiliate Disclosure. Changes in the area of linoleum floor tile that the ball collided with may have affected the height to which it bounced to thus producing variation between results. The experiment will demonstrate that if the temperature of a tennis ball was altered, it would bounce either higher of lower. This is correct unless the ball shows signs of reaching terminal velocity. It might be a good idea for students to experiment with a variety of balls to determine which one is most effective. 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. 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.
