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). Tennis balls are more likely to bounce on grass. 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. on different types of surfaces, then recorded the height of the bounce. Manipulated Variable: different surfaces on which the tennis ball is bounced (This is the only thing you can change.) Keep releasing pressure and repeating the experiment until the ball no longer bounces. This would provide evidence on how the height from which the ball is dropped from affects the height to which it bounces without air resistance. Do different kinds of balls bounce differently? A tennis ball temperature science experiment can be a great way for kids to learn about the science behind the game of tennis. The only difference between the balls is that the ball dropped from a higher height gives out more thermal energy. Which surface bounces a ball the highest? Do you have specific questions about your science project? When a ball drops in air there is air resistance to which the ball loses energy in the form of thermal energy. Each can from the same manufacturer can be different. 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. Do five drops on your first surface. 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. an incorrect and unreliable result. A cold ball will bounce farther than a warm one. A tennis balls trajectory is determined by its temperature. Our team of volunteer scientists can help. These both support my prediction and show that my prediction was correct. How can you measure the height a ball bounces? Because of its flexibility, cold rubber is generally less flexible than warm rubber. The steel snaps back more quickly when it hits the ground. All rights reserved. This is why it. What factors affect the bounce height of a ball? Balls bounce differently on different axes. The balls finish up with the same amount of energy and the only energy given out is thermal energy. These cookies track visitors across websites and collect information to provide customized ads. Acrylic-topped, this surface offers the most consistent ball bounce of all the outdoor tennis courts. Obviously, a ball won't bounce as high on carpet. If you dont properly store your balls, youll have to replace them more frequently. 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). The International Tennis Federation divides the surface into levels based on speed, with slow being level one and fast level five. Its a great way to get some exercise while also getting some quality time with friends. This is due to two factors. were able to construct a successful experiment. This blew the light balls away, giving us an unvalid result or catch. This is because the ball starts with more GPE. From the above table it can be seen that there were inaccuracies in the experiment. us. 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. Our team of volunteer scientists can help. that bounced the highest on the smooth concrete. Most experiments investigate the effect of an independent variable on a dependent variable. 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. - Paper x A lot of, Community Health and Population-Focused Nursing Field Experience (C229), Introduction to Environmental Sciences (ENVS 1301), Fundamentals of Information Technology (IT200), Clinical - RN Concept-Based Transition to Professional Nursing Practice (RNSG 1263), Introduction To Computer And Information Security (ITO 310), Primary Care Of The Childbearing (NR-602), Professional Nursing Practicum (NUR - 4836C), Legal Issues in Information Security (C 841), Electrical Machines and Power Electronic Drives (E E 452), Healthcare Strategic Management and Policy (HCM415), Strategic Human Resource Management (OL600), Professional Application in Service Learning I (LDR-461), Advanced Anatomy & Physiology for Health Professions (NUR 4904), Principles Of Environmental Science (ENV 100), Operating Systems 2 (proctored course) (CS 3307), Comparative Programming Languages (CS 4402), Business Core Capstone: An Integrated Application (D083), Civ Pro Flowcharts - Civil Procedure Flow Charts, C228 Task 2 Cindy - Bentonville - Passed with no revisions, 3.1.6 Practice Comparing Executive Organizations, Database Systems Design Implementation and Management 9th Edition Coronel Solution Manual, 1-2 Problem Set Module One - Income Statement, Mini Virtual Lab Calculating GPP and NPP1, Leadership class , week 3 executive summary, I am doing my essay on the Ted Talk titaled How One Photo Captured a Humanitie Crisis https, School-Plan - School Plan of San Juan Integrated School, SEC-502-RS-Dispositions Self-Assessment Survey T3 (1), Techniques DE Separation ET Analyse EN Biochimi 1. There is a chance that you will bounce. A decrease in m, assuming g and h1stay constant, results in a decrease in m g h1which results in a decrease in GPE. Place the tape measurer against the edge of a wall using the bluetack 3. Use a uniform surface to drop the ball onto. This experiment would provide me with more results that are relevant to the experiment that I have already conducted. Write your measurements down. Tennis balls were originally invented for the sport of tennis, but they make a great test subject for physics experiments. This would eliminate parallax error further. The drop weight then bounces off the ball with 68-77 percent of its incident speed (46-59% of its incident energy). Take your class outside, to an area with a smooth, flat surface. - Measuring tape x In this practical, students may use a variety of different balls to determine which type is most efficient. This is because the ball starts with more GPE. This cookie is set by GDPR Cookie Consent plugin. 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. 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. A lot of The higher the ball goes, the more GPE it ends up with. composition so it was higher up in the air, with this we were able to catch the balls in the execution of our experiment. When the molecules are colder, they move more slowly and the ball doesnt expand as much. We then bounced the balls on the surfaces and Grades: Preschool and K-2. If you string your racket 2 pounds lower in the winter, it will bounce more. Which ball will bounce higher off a hard surface? 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. 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. Why do balls bounce higher on different surfaces? The drag force increases as the ball goes faster. quicker and on time before they dropped back down. According to our background research, a The bounce of a cold superball is shorter than that of a warm superball. From dropping the ball we can see how high the ball will bounce to after having a loss or gain of energydue to sound or movement of the ball as it hits a hard surface. Hot balls were the more likely to bounce higher than cold balls. It shows that heights were recorded that exceeded the height that the ball would have reached had it been dropped in a vacuum. Cold balls tend to have a bouncier texture. = The distance between the bottom of the ball at the top of its arc after bouncing and the ground. Hypothesis. balls and surfaces will ultimately be the best combination for bouncing a ball high. 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. 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. Why Tennis Balls Bounce. Also the difference between the force of air resistance acting upon a ball travelling at 1ms, and the force of air resistance acting upon a ball travelling at 2ms, is far smaller than the difference between the force of air resistance acting upon a ball travelling at 20ms, and the force of air resistance acting upon a ball travelling at 21ms, , the faster the velocity that the ball reaches. 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. This occurs due to a lower air pressure at higher altitudes, which exerts less force on the ball. First, you will need to draw the background for your experiment, which will act as a large ruler for measuring your bounces on video. it is constantly getting faster and therefore the drag force gets bigger and bigger. 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. Aim: to find out which surface bounces a ball the highest. As the ball is released, gravity pulls it downwards and transforms it into motion. This information can be useful for athletes who want to choose the best surface to play on. 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. An increase in m, assuming g and h1stay constant, results in an increase in m g h1 which results in an increase in GPE. The ball weighs exactly 2.5g. measured the heights. This is called the relative speed. Therefore the ball dropped from the higher height must give out more thermal energy in order to end up with the same amount of energy as the other ball. It therefore hits more air particles each second and so the force of drag is bigger the faster the ball goes. ball bounced 6 inches. What do you think this means about your results? Drop each ball from a distance of 1 meter onto the surface and record how high it bounces in meters (Example: .46 meters). Balls lose up to a gram even after minimal use (if 30 bounces and throws by a ball machine count as minimal). The bounce of the ball is a major factor in the game of tennis. Air is pumped into the ball and causes it to bounce. the higher it popped up into the air. 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. 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. If you are looking for a challenging sport, tennis is an excellent choice for the winter months. Warmer balls bounce better than cold ones. 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. For a squash ball, f might be less than 0.5 or 0.25 - squash balls are not very bouncy. Keep a close eye on the ball, and instruct Phlebas to do the same. Which surface bounces a ball the highest? 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. - Pencil x To be consistent, again measure to the bottom of the ball. The tennis balls bounce in different ways. 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). 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. One of the hunks of information we found was would bounce the highest on a hard, smooth concrete surface because a rubber ball Tennis balls should ideally be kept at temperatures greater than 68 degrees Fahrenheit or 20 degrees Celsius. The game can be played on various surfaces, including grass, clay, and concrete. There is an activity at home that can be used to investigatebounciness. 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. Therefore any change to the weight of the ball will affect the energy the ball has initially, which, as previously stated, affects the height to which the ball bounces. When the temperature drops, gas molecules in close proximity. By conducting our experiment, we learnt that well-inflated rubber balls bounce the These cookies ensure basic functionalities and security features of the website, anonymously. energy a surface absorbs, the more of it will remain for a ball to bounce. 70% is retained. Is it a straight line? During the preliminary experiment it was established that time was not an important factor that had to be taken into account when deciding how many different heights to drop the ball from and the interval between those heights. This cookie is set by GDPR Cookie Consent plugin. Few independent variables will be changed, so the investigation is easy to manage, and the data is easier to process. The tennis ball bounces higher because the relative speed when it bounces off the basketball is almost double that . Click the "Experiment" button to find out! This applies to a ball falling in a vacuum. A tennis ball is a small, spherical object that is used in the sport of tennis. Try bouncing different kinds of balls to test this question. Since Because air is a gas, when compressed, it becomes harder and pushes back harder than any other substance. 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 changes in shape are due to a balance of forces and energy: "When you drop a ball, gravity pulls it toward the floor. Abstract and Figures. The exact interval will be determined after the preliminary experiment, as will the number of heights that the ball will be dropped from. Belowis the graph of h1against h2. All rights reserved. As in both cases the main form of energy is GPE it follows that the higher the ball is dropped from, the higher the ball will bounce. Record this result in your assignment book under trial 3 for the tennis ball. The more particles per cubic meter, the more drag acting upon the ball. Concrete got bounced on the most, 5 times, and the highest, 55cm. 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 chains stretch back out as rubber cools, allowing the original form to return. As they are pushed about, the molecules in the ball collide with and rub across each other." 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. 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. Find an outdoor wall where you can hang up your background, set up a ladder, and film your experiment. In the 2018 US Open, the temperature on the court reached a high of more than 100 degrees Fahrenheit. Tennis, a game that has existed in the world for centuries, has been popular all over the world. External factors, i.e. 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. Let the ball bounce until it stops, and then stop recording. Decide on a height you want to drop the balls from . 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. For the higher heights the distance from h1 to h2 was almost a meter which meant it was difficult to get eye level from h1 to h2 to accurately in a short amount of time. This was when the ball was falling in air. 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. This means that the faster that the ball travels the larger the force of air resistance upon it. 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. . The air in the ball expands and contracts as it is compressed. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. The ball has reached its terminal velocity and cannot fall any faster (unless dropped in a vacuum). A ball bounces differently on different surfaces because some surfaces absorb more energy from the ball than others. will start at 2m and then move down in intervals of 10cm to 10cm. Therefore of the GPE that the ball possessed at the beginning some energy is given off as thermal energy. Let the ball bounce until it stops, and then stop recording. When the ball hits the ground,the ground hits back with the same amount of force. To determine how high a tennis ball will bounce when dropped from a . There are many other great ball projects in this fun book by Madeline P. Goodstein. Does a tennis ball bounce differently on different surfaces? The results are shorter rallies and quicker points. 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 . Not The difference between the predicted height and the actual height will provide evidence as to how air resistance affects the flight of the ball. This would allow one to find the terminal velocity of the ball. Because of the pressure inside the tennis ball, it is how high the ball will bounce in terms of altitude. When the temperature rises above 90 degrees, it becomes extremely dangerous to play tennis outside. At 2ft, the basketball bounced 15 inches, the tennis ball bounced 12 inches, and the golf. 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.
