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. Reproduction of material from this website without written permission is strictly prohibited. Once the drag force equals the gravitational force all forces are equal and acceleration stops. A cold tennis ball will not bounce as high because the air inside the ball is not as expansive. 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. However if two results are recorded that do not fit the trend of other results nor are close to results recorded for that height then the experiments accuracy would be brought into doubt. Then draw a line to connect the dots. 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. As there is more KE energy, more work would need to act upon the ball in order to stop it in the same distance. The ball gains energy of motion, known as kinetic energy. The ball moves upwards, reaching stage 1, i.e., maximum height, and its velocity is momentarily zero. Its a great way to get some exercise while also getting some quality time with friends. This means that the faster that the ball travels the larger the force of air resistance upon it. It will not have enough force to bounce if it is lit. As they are pushed about, the molecules in the ball collide with and rub across each other." A glass ball will bounce higher than a rubber ball if it doesnt break. It therefore hits more air particles each second and so the force of drag is bigger the faster the ball goes. (Image by Harold E. "Doc" Edgerton), http://www.exploratorium.edu/sports/ball_bounces/index.html, http://www.exploratorium.edu/baseball/bouncing_balls.html, Playing the Angles: The Physics of Balls Bouncing Off of Surfaces. 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. 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. half the results (concrete), we were incorrect about the basketball. For a squash ball, f might be less than 0.5 or 0.25 - squash balls are not very bouncy. Abstract and Figures. The energy chain is as follows: Therefore as energy cannot be created or destroyed the energy the ball starts with must be directly proportional to the energy the ball finishes with, at the top of its bounce, and so if the ball starts with more energy it must therefore finish with more. Now use your data table to plot points on the graph. This means that the higher h. will differ from the height that the ball would have reached had it been dropped in a vacuum. Once the ball hits the ground, its displacement is momentarily zero. The temperature of a tennis ball can affect its bounce height. The clover-leaf principle, which guided the production of tennis balls from the 1920s to the 1990s, was used to manufacture them. Carpet2. As the ball falls it hits against air particles. There are more than 160 different types of tennis surfaces. 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. What factors affect the bounce height of a ball? A similar length stick, marked in 5-10cm bands of colour. 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. This applies to a ball falling in a vacuum. According to our background research, a We use cookies and those of third party providers to deliver the best possible web experience and to compile statistics. 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 . These cookies will be stored in your browser only with your consent. 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). 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. There is a chance that you will bounce. The colder, the lower the ball bounces, and vice versa. 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. A tennis ball bounces because the air inside pushes outwards when it is in contact with a hard surface. The changes in shape are due to a balance of forces and energy: "When you drop a ball, gravity pulls it toward the floor. What material makes a ball bounce higher? As the ball has less KE and is travelling slower it becomes stationary faster at the top of its arc. 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. The reason balls bounce is quite advanced science. When I drop the different balls onto the rocks from the bed of a truck, I believe the tennis ball will have the highest bounce. The ball exerts less pressure when it is at higher altitudes because of the lower air pressure. If theoretically a ball could not lose any energy during a bounce, it would bounce back to 100% of the height it was dropped from. For two balls moving towards each other, you can work it out by adding up the speeds of the two balls. Then they would be dropped from a table, and the height would be measured. The difference between the predicted height and the actual height will provide evidence as to how air resistance affects the flight of the ball. For multiple bounces, it's just like dropping the ball again from a reduced height. For any other use, please contact Science Buddies. 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. Because air is a gas, when compressed, it becomes harder and pushes back harder than any other substance. Tennis balls bounce differently in the high altitude and at sea. For any other use, please contact Science Buddies. Line up the top of the table tennis ball with the top of the metre ruler (i.e. This proves that the higher h1the more h2will differ from the height that the ball would have reached had it been dropped in a vacuum. 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. 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. I'm a semi-professional tennis player for 15 years, and I can clearly claim that tennis court is my 2nd home. The bouncing of a tennis ball on a tennis court surface is analysed by making several simplifying assumptions about the physics of the interaction. 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. Use the pressure gauge to release some of the air pressure from the ball. At 3ft, the basketball bounced 20 inches, the tennis ball bounced. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. A ball bounces in an arc, so measure the height at the top of the arc of the first bounce. The harder the court surface is, the higher the rebounded ball will be. Length of Lesson: 30 - 45 minutes. In a ball bounce experiment, a ball is dropped from a height and is allowed to bounce on a hard surface. 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. As the ball falls to the surface it has kinetic energy. This means it will be travelling the same speed when it hits the ground. 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. Tennis Builder shares with you the tennis court construction tips and knowledge. It might be a good idea for students to experiment with a variety of balls to determine which one is most effective. Why do balls bounce higher on different surfaces? One way to do this is to put the ball in a bowl of hot water for a few minutes. The cookie is used to store the user consent for the cookies in the category "Other. We also use third-party cookies that help us analyze and understand how you use this website. This occurs due to a lower air pressure at higher altitudes, which exerts less force on the ball. 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. composition so it was higher up in the air, with this we were able to catch the balls Copyright 2002-2023 Science Buddies. Which surface bounces a ball the highest? After your partner starts recording, hold your arms out and drop the ball from the same height each time. When the ball was dropped from the higher heights the ball began to show signs of reaching its terminal velocity before it reaches the ground. Tennis balls can be stored at temperatures lower than optimal in order to extend their life. As for catching the balls on time, we changed our hand positioning and h1 = The distance between the bottom of the ball before it is dropped and the ground. 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. Then when dropping the ball again eye level was kept level with the blue tack. 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. Also it will affect its bouncing properties. 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. ball bounced 6 inches. The ball has reached its terminal velocity and cannot fall any faster (unless dropped in a vacuum). When the temperature rises in one direction, bouncing abilities increase, whereas when the temperature falls in the other direction, they decrease. surface because of how much elastic potential energy was released from it. Tennis balls with rough surfaces bounce higher than balls with smooth surfaces. 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. Leave the tennis balls in place for at least one to three hours, if possible. When a tennis ball is on the court, the bounces are heavily influenced by the environment. This is correct unless the ball shows signs of reaching terminal velocity. When the temperature drops, gas molecules in close proximity. 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. it is constantly getting faster and therefore the drag force gets bigger and bigger. To be consistent, again measure to the bottom of the ball. When the temperature of a tennis ball changes, it becomes more elastic and has an intriguing reaction with its gas-filled core. Tennis cannot be played at a certain temperature; however, 70-90 degrees Fahrenheit is ideal. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. The impact duration was between 65 and 71 ms. Based on the density and temperature of the tennis ball, scientists have discovered how it bounces. Why do golf balls bounce so high on concrete? 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. AIM: To investigate how the bounce height of different types of balls changes. The height of the ball at each bounce is then calculated. 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. 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 more energy that the ball possessed before being dropped, the more energy was converted into KE while the ball fell. Results are presented for a tennis ball, a . To find out what affects the height to which a ball bounces. If the drag is less the ball will fall faster and is less likely to reach its terminal velocity. - tennis ball x However, you may visit "Cookie Settings" to provide a controlled consent. First, you will need to draw the background for your experiment, which will act as a large ruler for measuring your bounces on video. This is because it is easiest as the figure read of the meter rule is the result. If you're playing under 68 degrees, it's a good idea to make sure the ball doesn't bounce too much. 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. Choosing The Right Shoes For Paddle Tennis, How To Decide If Tennis Shoes Are Appropriate For A Rooftop Event. Write your measurements down. 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. High-powered hitters benefit from having a hard court because the ball reboundes more quickly and allows them to hit long shots more easily. Increased energy and movement results in a bounce. You also have the option to opt-out of these cookies. The bounce of a cold superball is shorter than that of a warm superball. Method:The apparatus will be set up as shown: H is the height of the ball before it is dropped. 30% of the energy that the ball hits the floor wit is lost. Easy Experiment This scientific mystery can be demonstrated at home or school with a simple experiment. experiment. The higher the height from which the ball was dropped from, the higher the height to which it bounced. Equipment/materials used: A tennis ball is a small, spherical object that is used in the sport of tennis. Therefore, Not The clay surface slows the ball down more than the grass of Wimbledon, allowing Nadal to use his forehand to his advantage. After the ball reaches terminal velocity, no more GPE is converted into KE is the ball cannot get any faster. A decrease in bounce is caused by a colder temperature. 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. Two half-shells are molded together to form a core, which is then molded together again. Do you have specific questions about your science project? This is because it is the easiest and quickest variable to alter. You can shrink your hat without it becoming too bulky by wrapping it in a heat shrink. The grass does not provide as much upward rebound when the ball hits it. However the conditions were kept the same for each drop of the ball. found that different surfaces absorb different amounts of energy, and the less Please enter a search term in the text box. h1will start at 2m and then move down in intervals of 10cm to 10cm. The bounce of the ball is a major factor in the game of tennis. Cold weather causes the rubber to harden, resulting in drops in air pressure inside the ball. 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. This will hopefully discount any anomalies automatically and leave us with three accurate and reliable results. We could have improved this Drag is a squared function of velocity and therefore as the ball drops drag increases a greater amount each second. Five repeats were done as it was deemed that an average of the middle three was reasonably accurate. Apparatus:Clamp stand, meter rule 2, table tennis ball, desk. Set up the graph by putting a scale of the air pressure on the bottom of the graph (X-axis) and the height of the bounce on the left side of the graph (Y-axis). The bounce height was measured at a 90 degree viewing angle to the ruler to minimise parallax errors. Please enter a search term in the text box. This is because it is easiest as the figure read of the meter rule is the result. Cold balls tend to have a bouncier texture. . 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. Therefore, our hypothesis was refuted by our final results. A hard surface, such as concrete, absorbs less energy compared with a soft surface, such as a carpeted floor. us. 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. 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. 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. To determine how high a tennis ball will bounce when dropped from a . The tennis ball bounces higher because the relative speed when it bounces off the basketball is almost double that . As an example, on the day we performed our experiment, a strong wind was Therefore, harder surfaces will ultimately bounce a ball higher. A cold ball typically has less bounce than a warm ball. 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. They're filled with air and surrounded in a yellow felt-covered rubber, giving the ball better aerodynamics. Answer (1 of 2): Some surfaces absorb more energy than others do. Section II: Hypothesis. The Graph on page 23 shows that all of the results were very close together. It shows that heights were recorded that exceeded the height that the ball would have reached had it been dropped in a vacuum. 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. Keep your balls warm in order to get the best bounce possible. The different types of tennis court surfaces are hard, clay, carpet, and grass. Method: 1. the concrete surface is the hardest surface, it allowed more energy to be released 1 tennis ball 1 golf ball. 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 results of the experiment were obtained with a method that ensured that every drop was under similar conditions which ensured a fair test. Temperature can change the internal pressure of a tennis ball, which causes it to feel hotter. Launch Related Video : The Hawk Factor. Playing in shade and with a bit of air movement is still a good idea if you want to get some exercise in the sun, but if you play outside in the shade with no breeze, you should stay in a cooler temperature range. 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. This would allow the actual coefficient to restitution to be calculated. It provided me with five repeats so that the maximum and minimum results could be discounted and a reliable average could be taken. Although catching small balls was an issue, we solved it by getting our better Make a line at the top to indicate where you will drop the ball from, so that it will be the same for each test. A decrease in h1, assuming g and m stay constant, results in a decrease in m g h1which results in a decrease in GPE. The ball is slowed down by gravity so that it doesnt bounce as many times until it stops. The bounce should be between 53 and 58 inches. The steel has a lot of bounce power due to its better storage of energy. Measuring tape 3. A cold ball will bounce farther than a warm one. This website uses cookies to improve your experience while you navigate through the website. A variety of surfaces can be used to create a tennis court, each with its own characteristics which affect the playing style of the game. We then bounced the balls on the surfaces and, measured the heights. Reproduction of material from this website without written permission is strictly prohibited. Science Buddies Staff. There are many other great ball projects in this fun book by Madeline P. Goodstein. Copyright 2023 StudeerSnel B.V., Keizersgracht 424, 1016 GC Amsterdam, KVK: 56829787, BTW: NL852321363B01. Why Does One Tennis Shoe Pull Your Sock Down? Make a line graph of your data. it goes back into the ball, giving it more force to pop back up into the air. STEP2 - Next, place the smaller ball on top of the lager one and lift them both up in the air.. STEP3 - Drop em'!. The air in the ball expands and contracts as it is compressed. Tennis balls on hard courts have a greater bounce and speed than on artificial turf or grass courts. Since The experiment will demonstrate that if the temperature of a tennis ball was altered, it would bounce either higher of lower. 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. energy a surface absorbs, the more of it will remain for a ball to bounce. You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use. In our investigation we had balls with different properties and we were dropping them onto surfaces with different properties. As there is more GPE more energy is converted into KE (The ball is going faster, KE=1/2mv. Carefully climb the ladder with the ball. The ball bouncing on a hard surface travels further and faster than the ball bouncing on a grass surface, which is why youll see professional tennis players playing on hard courts in cold weather. You can also try using a hair dryer to heat the ball up. The harder the court surface is, the higher the rebounded ball will be. Air pressure will affect the balls fall slightly as the concentration of air particles per cubic meter varies with air pressure. This means that we can approximately calculate the amount of energy that the ball conserves as it hits the floor and therefore the height to which it will bounce for any given height in a vacuum. Once the drag force equals the gravitational force all forces are equal and acceleration stops. Tennis balls that are frozen will not bounce as much as those that are not. A cold tennis ball bounces lower than a warm one. Drag is a squared function of velocity and therefore as the ball drops drag increases a greater amount each second. Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. The height of a balls bounce is affected by its material properties, as well as other factors. 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. 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. 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. It will not bounce to high if it is heavy. Masses of tennis balls range between 56.0 and 59.4 grams (2011). Try bouncing different kinds of balls to test this question. 1. When it hits the ground, the bottom of the ball becomes flat against the floor. Concrete got bounced on the most, 5 times, and the highest, 55cm. The ball shoots up with less energy because of this. At 2ft, the basketball bounced 15 inches, the tennis ball bounced 12 inches, and the golf. As velocity increases air resistance increases in proportion to the square of the velocity. External factors, i.e. Balls bounce in ways that are affected by gravity. Calculating the coefficient to restitution of ball hitting the floor: The coefficient to restitution can be found out from a graph of h1against h2. Do different kinds of balls bounce differently? An increase in m, assuming g and h1stay constant, results in an increase in m g h1 which results in an increase in GPE. were able to construct a successful experiment. Watch the video of the dropping tennis ball. Push it against the measuring tape, careful to keep it at the same height. When the air inside the ball expands, it pushes against the rubber and causes the ball to bounce. Different courts are better suited to each players style. Kinetic energy and ball shape. to find out which surface bounces a ball the highest. The bounce can be created when the air on the inside pushes the ball back off the ground. 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. The balls bounced higher on the concrete It should be tall enough to hang up behind your ladder, about 5feet tall. Fully pump up the basketball and check the pressure with the pressure gauge. results, one of the many being that the harder the surface the ball was bouncing on, This bouncing ball experiment is the perfect way to bring the topic of gravity to life with your class. The Swiss like to get points over and done with in a short period of time. What do you think this means about your results? Therefore the results are valid. Therefore the ball goes higher.
