As velocity increases air resistance increases in proportion to the square of the velocity. Try comparing a hot day to a cold day. rubber ball 39 cm 38 cm 41 cm 39 cm. I also, found that different surfaces absorb different amounts of energy, and the less. 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. Then when dropping the ball again eye level will be kept level with the blue tack thus avoiding parallax errors. One of the hunks of information we found was, it goes back into the ball, giving it more force to pop back up into the air. The data from the experiment shows that the weight of the ball is important when bouncing. SCIENTIFIC Method Aim & Hypothesis Method Variables Risk Assessment Results Conclusion & discussion Which surface bounces a ball the highest? For the most part, the document is a case study in compulsive precision. A tennis court is the venue where the sport of tennis is played. Watch the video of the dropping tennis ball. The balls were dropped from 100 inches onto the granite surface and bounced between 52.93 and 58.43 inches. You will use an air pump, a basketball, and an air pressure gauge to test if changing the air pressure will change the bounciness of the ball. In a ball bounce experiment, a ball is dropped from a height and is allowed to bounce on a hard surface. Graph 1. This cookie is set by GDPR Cookie Consent plugin. Does a tennis ball bounce differently on different surfaces? Do five drops on your first surface. 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. Once the drag force equals the gravitational force all forces are equal and acceleration stops. 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. Carpet2. Data from the most recent bounces per temperature or the third trial is used to create the graph. Decide on a height you want to drop the balls from . These cookies track visitors across websites and collect information to provide customized ads. Please enter a search term in the text box. 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. The surface onto which the ball is dropped upon will be kept the same. The balls bounced higher on the concrete When the air inside the ball expands, it pushes against the rubber and causes the ball to bounce. Concrete got bounced on the most, 5 times, and the highest, 55cm. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. 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. The tennis balls bounce in different ways. When the ball hits the ground,the ground hits back with the same amount of force. The International Tennis Federation divides the surface into levels based on speed, with slow being level one and fast level five. However the conditions were kept the same for each drop of the ball. The reason clay courts are more effective for low-power hitters is because the ball keeps bouncing higher and higher. or carpet. his the height of the balls bounce. When it reaches Earth, it collides head-on with an . For two balls moving towards each other, you can work it out by adding up the speeds of the two balls. The air in the ball expands and contracts as it is compressed. Hot balls were the more likely to bounce higher than cold balls. 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 steel snaps back more quickly when it hits the ground. Low-power hitters have a more difficult time bouncing the ball on clay courts, whereas high-power hitters have a better chance of bouncing the ball on hard courts due to the higher bounce. Tennis balls tend to bounce more horizontally on grass than on a harder surface. It will not bounce to high if it is heavy. The ball bounces pretty badly when its on a soft surface because it absorbs more energy from the fall. : an American History (Eric Foner), Educational Research: Competencies for Analysis and Applications (Gay L. R.; Mills Geoffrey E.; Airasian Peter W.), The Methodology of the Social Sciences (Max Weber), Biological Science (Freeman Scott; Quillin Kim; Allison Lizabeth), Campbell Biology (Jane B. Reece; Lisa A. Urry; Michael L. Cain; Steven A. Wasserman; Peter V. Minorsky), 4-3 Assignment Project Management Strategies. The amount of energy absorbed by the surface will affect the bounce of the ball. 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. bounces the highest on smooth concrete. Although catching small balls was an issue, we solved it by getting our better However, you may visit "Cookie Settings" to provide a controlled consent. For any other use, please contact Science Buddies. The effect of surface on the bounce height of a tennis ball. 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. This will hopefully discount any anomalies automatically and leave us with three accurate and reliable results. This experiment requires a ball that will bounce and a meter stick or other measuring device. Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features. The 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. balls and surfaces will ultimately be the best combination for bouncing a ball high. The aim of the experiment my partner and I performed was to find out which This occurs due to a lower air pressure at higher altitudes, which exerts less force on the ball. Belowis the graph of h1against h2. Reproduction of material from this website without written permission is strictly prohibited. quicker and on time before they dropped back down. 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. Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. Conclusion: But opting out of some of these cookies may affect your browsing experience. Different courts are better suited to each players style. As the ball falls to the surface it has kinetic energy. Apparatus:Clamp stand, meter rule 2, table tennis ball, desk. If we High-powered hitters benefit from having a hard court because the ball reboundes more quickly and allows them to hit long shots more easily. The ball shoots back up after being slowed down. The balls finish up with the same amount of energy and the only energy given out is thermal energy. The more particles per cubic meter, the more drag acting upon the ball. Try comparing two days with different atmospheric pressure. hypothesis, we predicted that a rubber ball would bounce the highest on rough Keep a close eye on the ball, and instruct Phlebas to do the same. All rights reserved. Air resistance exists but does not affect the velocity of the ball significantly. Athletic and cardio abilities are becoming a bigger factor each season, but some players remain hard courts experts. Therefore the heavier the ball is, the faster its terminal velocity. This is because it is easiest as the figure read of the meter rule is the result. and tries to catch the balls on time. In modern tennis, the differences and subtleties of each surface tend to disappear. This is called the relative speed. Grades: Preschool and K-2. The equipment necessary to generate these conditions was not available and as a result the results obtained were not one hundred percent accurate. the concrete surface is the hardest surface, it allowed more energy to be released This will be repeated five times, possibly more (for accuracy), for each height and the top and bottom results will be discounted. The exact interval will be determined after the preliminary experiment, as will the number of heights that the ball will be dropped from. Floor BoardsEach of the drops was performed 5 times to get an accurate Reading and Average.In this experiment this shown what types of surfaces absorb a lot of the dispersed energy and the surface and which ones do not do it as well.This was done on iMovie and took 2 Hours to Create.So Please Enjoy! 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. Tennis balls are more likely to bounce on grass. This is correct unless the ball shows signs of reaching terminal velocity. The balls finish up with the same amount of energy and the only energy given out is thermal energy. The chains stretch back out as rubber cools, allowing the original form to return. This means that the faster that the ball travels the larger the force of air resistance upon it. Acrylic-topped, this surface offers the most consistent ball bounce of all the outdoor tennis courts. This means that not all the GPE is converted into KE as it would have been if the ball had been dropped in a vacuum. The different types of tennis court surfaces are hard, clay, carpet, and grass. Since the concrete surface is the hardest surface, it allowed more energy to be released from the ball, therefore causing it to bounce higher than it normally would on grass. What affects ball bounce? Each can from the same manufacturer can be different. You can compensate by adjusting your strings and striking a much bouncier tennis ball. This was when the ball was falling in air. Most experiments investigate the effect of an independent variable on a dependent variable. (2020, November 20). 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. The harder the court surface is, the higher the rebounded ball will be. This is because it is easiest as the figure read of the meter rule is the result. The balls leave the floor at the same speed with the same amount of KE and so both balls reach the same height and end up with the same amount of GPE at the top of their bounces. = The distance between the bottom of the ball before it is dropped and the ground. When the temperature is below 68 degrees, the ball will bounce less. Abstract and Figures. 70% is retained. Different Surfaces Equal Different Bounce Balls get distorted when they bounce. 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. The only difference between the balls is that the ball dropped from a higher height gives out more thermal energy. 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. When the temperature drops, gas molecules in close proximity. 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. Method:The apparatus will be set up as shown: H is the height of the ball before it is dropped. 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. . concur, which was catching the small balls. Is it a straight line? 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. "That's The Way The Ball Bounces," The Exploratorium Museum, San Francisco, CA. 3. The bounce of the ball is a major factor in the game of tennis. 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. It relates to how much energy balls have, what they are made of, how they change shape and where the energy they have goes. The results of the experiment were obtained with a method that ensured that every drop was under similar conditions which ensured a fair test. To find out what affects the height to which a ball bounces. h2= The distance between the bottom of the ball at the top of its arc after bouncing and the ground. 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. If you're playing under 68 degrees, it's a good idea to make sure the ball doesn't bounce too much. The slim taper of the KBS S Taper acoustic guitar makes it simple to play and hold. A ball that is dropped in air however is subjected to air resistance which affects the height to which it bounces. STEP4 - Watch as the smaller ball flies off into the air! Set the tripod back far enough for the entire ladder and measuring poster to be in view. As they are pushed about, the molecules in the ball collide with and rub across each other." 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. A cold tennis ball bounces lower than a warm one. Note whether the ball and surface showed more of an elastic or inelastic collision. As a result, the ball is lifted in this manner. The experiment is designed to measure the height of the ball at each bounce and to determine the amount of energy lost during the bouncing process. Section II: Hypothesis. This is the reason we put in our hypothesis that a The first independent variable that will be tested. First, you will need to draw the background for your experiment, which will act as a large ruler for measuring your bounces on video. 2. You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use. I will drop the ball 3 The approach was to place 3 tennis balls in 4 different environments with different temperatures. Why a ball bounces: The ball's energy is matched by the ground it hits. Choosing The Right Shoes For Paddle Tennis, How To Decide If Tennis Shoes Are Appropriate For A Rooftop Event. The tennis balls bounce in different ways. 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. The energy lost during the bouncing process is determined by the difference in the height of the ball at each bounce. Take a ball and place it on the 150 cm line and drop it. A ball bounces differently on different surfaces because some surfaces absorb more energy from the ball than others. Use the pressure gauge to release some of the air pressure from the ball. Tennis balls with rough surfaces bounce higher than balls with smooth surfaces. To determine how high a tennis ball will bounce when dropped from a . h1will start at 2m and then move down in intervals of 10cm to 10cm. 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. Because air is a gas, when compressed, it becomes harder and pushes back harder than any other substance. Carefully climb the ladder with the ball. Length of Lesson: 30 - 45 minutes. If you are looking for a challenging sport, tennis is an excellent choice for the winter months. - Ping pong ball x Concrete will help bounce a ball the highest as it's hard and, My partner and Is experiment which surface bounces a ball the highest?, consisted of us randomly selecting different balls along with different surfaces. But how does concrete . How does the material of a ball affect its bounce? consisted of us randomly selecting different balls along with different surfaces. This is impossible. Most of the points on grass are very short. This is longer than the 5-8 ms ball bounce from a solid surface or racquet. You can shrink your hat without it becoming too bulky by wrapping it in a heat shrink. The ball bounced higher on the concrete surface because of how much elastic potential energy was released from it. changing air density, temperature. Therefore the ball goes higher. 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. measured the heights. Line up the top of the table tennis ball with the top of the metre ruler (i.e. When printing this document, you may NOT modify it in any way. The combination of the material properties of a ball (surface textures, actual materials, amount of air, hardness/ softness, and so on) affects the height of its bounce. Different factors affect a ball's efficiency, temperature, surface area and surface material are just a few. We also use third-party cookies that help us analyze and understand how you use this website. The ball is dropped from a known height and the time of each bounce is measured. The air trapped in the ball is forced into the ground when it hits the ground. In this experiment you will use a ball filled with air. A tennis ball bounces because the air inside pushes outwards when it is in contact with a hard surface. 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. Aim:To find out what affects the height to which a ball bounces. Drag is a squared function of velocity and therefore as the ball drops drag increases a greater amount each second. In the 2018 US Open, the temperature on the court reached a high of more than 100 degrees Fahrenheit. When a bouncing ball falls, it initially gains speed or kinetic energythe energy of motion. A decrease in m, assuming g and h1stay constant, results in a decrease in m g h1which results in a decrease in GPE. Few independent variables will be changed, so the investigation is easy to manage, and the data is easier to process. Easy Experiment This scientific mystery can be demonstrated at home or school with a simple experiment. "Balls Bouncing Off of Surfaces.". results, one of the many being that the harder the surface the ball was bouncing on, 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. It shows that heights were recorded that exceeded the height that the ball would have reached had it been dropped in a vacuum. Therefore the height that it reaches is less high. A lot of 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 tennis ball bounces higher because the relative speed when it bounces off the basketball is almost double that . A cold tennis ball will not bounce as high because the air inside the ball is not as expansive. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. 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. - Rubber ball x For multiple bounces, it's just like dropping the ball again from a reduced height. When printing this document, you may NOT modify it in any way. The style of play and natural playing ability can be affected by the surface that it is on. = The distance between the bottom of the ball at the top of its arc after bouncing and the ground. It does not store any personal data. 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. were able to construct a successful experiment. The cookies is used to store the user consent for the cookies in the category "Necessary". So whether you're looking to learn more about the sport or just stay up-to-date on the latest news, we've got you covered. Repeat the process three times with the same ball and record results. Place one of the tennis balls in the freezer for 20 mins 2. Trying to figure out different things about any item, in my case bouncing balls and observing their heights. 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. Five repeats were done as it was deemed that an average of the middle three was reasonably accurate. Balls bounce in ways that are affected by gravity. We 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. is well-inflated and made of rubber which would give it more kinetic energy and It should be on a smooth cement surface for optimal ball bouncing. Tennis balls bounce differently in the high altitude and at sea. As an example, on the day we performed our experiment, a strong wind was Tennis balls were originally invented for the sport of tennis, but they make a great test subject for physics experiments. As a result, they move at a slower rate of speed with less energy. C. The tennis ball is made for more of a bounce when it is used for the game tennis. Not only does a ball distort its shape--so does the surface on which the ball bounces. When the ball hits the floor and stops, that energy has to go somewhere. 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. Instead, as the ball is still always loosing GPE so long as it is still falling, all GPE is converted into thermal energy. The longer it takes to stop, the higher it bounces to. 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. hard ball made of rubber should bounce the highest on a concrete surface, which We use cookies and those of third party providers to deliver the best possible web experience and to compile statistics. 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. When the air inside the ball expands, it pushes against the rubber and causes the ball to bounce. 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 is because the ball starts with more GPE. we were able to work our way around them, giving us a more successful Averages are more reliable than using one result as they take into account variation between results. Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. 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. on different types of surfaces, then recorded the height of the bounce. A similar length stick, marked in 5-10cm bands of colour. . , v is greater therefore KE is greater by a larger amount). It shows that heights were recorded that exceeded 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. Each of the following experiments tests a different hypothesis. 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. This is because it is the easiest and quickest variable to alter. was proven correct after our experiment. You can also try using a hair dryer to heat the ball up. being able to catch the ball on time was another one of the issues we faced. You also have the option to opt-out of these cookies. Doherty, P., 1991. 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. The ball shoots up with less energy because of this. Use the measuring tape to measure 150 cm off the ground. The higher the height from which the ball was dropped from, the higher the height to which it bounced. To a wider range of results i.e. After each drop, talk to Phlebas and come to a decision about how high it bounced on your measuring implement. It would also be fun to explore the effect of different surfaces on the bounce of the bouncy ball. The trip is going to be thoroughly enjoyable. an incorrect and unreliable result. This causes thermal energy to be given off. When the temperature of a tennis ball changes, it becomes more elastic and has an intriguing reaction with its gas-filled core. - Measuring tape x 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. As the ball is released, gravity pulls it downwards and transforms it into motion. Science Buddies Staff. The grass does not provide as much upward rebound when the ball hits it. Why do balls bounce higher on different surfaces? High bounce ball 2. Does the weather make a difference?
