Decide on a height you want to drop the balls from . Then they would be dropped from a table, and the height would be measured. But how does concrete . METHOD: 1. The ultimate answer was that a basketball The steel has a lot of bounce power due to its better storage of energy. Grades: Preschool and K-2. If you are looking for a challenging sport, tennis is an excellent choice for the winter months. The Swiss like to get points over and done with in a short period of time. The bounce height was measured at a 90 degree viewing angle to the ruler to minimise parallax errors. 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. Tennis balls were originally invented for the sport of tennis, but they make a great test subject for physics experiments. A ball that is dropped in air however is subjected to air resistance which affects the height to which it bounces. Write each measurement in the data table. The cookie is used to store the user consent for the cookies in the category "Other. Few independent variables will be changed, so the investigation is easy to manage, and the data is easier to process. 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. 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 ball bounces pretty badly when its on a soft surface because it absorbs more energy from the fall. The Physics of Grass, Clay, and Cement. 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. When the temperature is below 68 degrees, the ball will bounce less. Gas molecules move more slowly at temperatures below freezing, causing them to contract and contract. Tennis balls are different at sea level and at high altitudes. The acceleration due to gravity causes the ball to change direction and start moving downwards at stage 2. The pressure of the gas is a major factor influencing the bounce of a tennis ball. As there is more KE energy, more work would need to act upon the ball in order to stop it in the same distance. This is why you should have seen that when you bounced the basketball on a relatively hard surface it bounced higher (it lost less energy) compared with when it was bounced on a softer surface . 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. Gather 15 to 20 tennis balls and a measuring tape. 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. Use the pressure gauge to release some of the air pressure from the ball. Keep a close eye on the ball, and instruct Phlebas to do the same. An average will then be taken. Introduction: 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. This means it will be travelling the same speed when it hits the ground. When a bouncing ball falls, it initially gains speed or kinetic energythe energy of motion. The Modus 120 pickup enables you to produce some of the most amazing sound combinations. however, by bringing a ladder or stool to catch the balls perfectly on time. KE = 1/2mv where m = mass and v = velocity, 1/2mv = mhg - thermal energy (lost as a result of drag). Tiles3. Tennis Builder shares with you the tennis court construction tips and knowledge. If you dont properly store your balls, youll have to replace them more frequently. There is a chance that you will bounce. Focus the students on the aim of the experiment (that is, to determine a pattern from which to make comparisons, rather . Some of the balls energy can be converted into heat. This cookie is set by GDPR Cookie Consent plugin. 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. There is an activity at home that can be used to investigatebounciness. Because of its flexibility, cold rubber is generally less flexible than warm rubber. Therefore the results are valid. The weight and material of the ball will be kept the same throughout the experiment by using the same ball. Keep releasing pressure and repeating the experiment until the ball no longer bounces. Then when it bounces up, it returns to its original shape. Therefore the ball goes higher. Necessary cookies are absolutely essential for the website to function properly. Will the air pressure change the bounciness of a ball? Science Buddies: Pilobolus Spore Sac Launch. Conclusion: As the molecules expand and float in an endless loop, the amount of energy they produce increases. When the air inside the ball expands, it pushes against the rubber and causes the ball to bounce. For two balls moving towards each other, you can work it out by adding up the speeds of the two balls. 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. For the most part, the document is a case study in compulsive precision. Hot balls were the more likely to bounce higher than cold balls. It would also be fun to explore the effect of different surfaces on the bounce of the bouncy ball. This would allow one to find the terminal velocity of the ball. This means that KE is the same for both balls when each ball hits the ground. Take a ball and place it on the 150 cm line and drop it. 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. However, you may visit "Cookie Settings" to provide a controlled consent. Removing the maximum and minimum results and taking an average of the middle three results also provided more accurate results. Why does Rafael Nadal do so well on the clay? It relates to how much energy balls have, what they are made of, how they change shape and where the energy they have goes. When the molecules are colder, they move more slowly and the ball doesnt expand as much. Discussion: A cold tennis ball will not bounce as high because the air inside the ball is not as expansive. Use a uniform surface to drop the ball onto. Repeat steps 1-6 with the different balls. The ball did not reach terminal velocity however as it did not have enough time to accelerate to its terminal velocity. The mass of the ball will affect the height the ball bounces to because it affects the balls starting energy. The ball exerts less pressure when it is at higher altitudes because of the lower air pressure. The cookies is used to store the user consent for the cookies in the category "Necessary". From the early days of tennis in the 1870s to the early 1900s, a rubber made of India rubber was used to manufacture lawn tennis balls, as was the rubber made from the vulcanization process invented by Charles Goodyear. When dropped on a solid surface, not even a super ball bounces back as high as its initial height, but some balls do bounce a lot better than others. You can even play tennis outside in any weather. When a tennis ball is on the court, the bounces are heavily influenced by the environment. Calculating the coefficient to restitution of ball hitting the floor: The coefficient to restitution can be found out from a graph of h1against h2. 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. This is because as the ball goes faster it passes through a greater volume of air each second. Note whether the ball and surface showed more of an elastic or inelastic collision. Science Buddies Staff. Increased energy and movement results in a bounce. Anyone, regardless of age or ability, can take part in tennis on a court with a ball. Its not just a game for the wealthy; its also a game for everyone. This will be called the average of the middle three repeats. Belowis the graph of h1against h2. This is due to two factors. experiment. This is why it. Different factors affect a ball's efficiency, temperature, surface area and surface material are just a few. A hard surface, such as concrete, absorbs less energy compared with a soft surface, such as a carpeted floor. 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. This is correct unless the ball shows signs of reaching terminal velocity. The colder, the lower the ball bounces, and vice versa. H is the height of the ball before it is dropped. A totally accurate experiment would have a variation between results equal to zero however an experiment that is totally accurate needs to be conducted under conditions where air pressure and temperature remained constant, error produced by the ball falling on different parts of the linoleum floor tile (which was not totally even and thus produces inaccurate results) and human error removed by dropping the ball onto a uniform surface and using machinery to record the height to which the ball bounced to. 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 is the reason we put in our hypothesis that a 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. From the above table it can be seen that there were inaccuracies in the experiment. will 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. 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 This is impossible. that bounced the highest on the smooth concrete. I do not believe that any ball will reach terminal velocity in this experiment seeing as the maximum height that they can be dropped from is 2m and, as the ball is quite smooth, I do not believe that it will have enough time to accelerate to its terminal velocity before it hits the floor. The steel ball on an unvarnished pine wood floor may not bounce at all, but rather make a dent, and so what the floor is made out of makes quite a lot of difference.

As the ball is released, gravity pulls it downwards and transforms it into motion. One of the hunks of information we found was I will drop the ball 3 However when the ball is dropped from a relatively low height, drag 0. What was the outcome? [accessed August 4, 2006]. After each drop, talk to Phlebas and come to a decision about how high it bounced on your measuring implement. Section II: Hypothesis. 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.
