tennis ball bounce on different surfaces experimenttennis ball bounce on different surfaces experiment

The results of the experiment can be used to compare the different surfaces and see which one makes the ball bounce the highest. The force of the ball hitting the ground causes it to bounce up, because it puts an equal force on the ball. Its not just a game for the wealthy; its also a game for everyone. My partner and Is experiment which surface bounces a ball the highest? The bounce of a cold superball is shorter than that of a warm superball. I think this is In our investigation we had balls with different properties and we were dropping them onto surfaces with different properties. Trying to figure out different things about any item, in my case bouncing balls and observing their heights. The ball did not reach terminal velocity however as it did not have enough time to accelerate to its terminal velocity. It will be vinyl tiling. will differ from the height that the ball would have reached had it been dropped in a vacuum. As they are pushed about, the molecules in the ball collide with and rub across each other." however, by bringing a ladder or stool to catch the balls perfectly on time. The average variation between results was 3cm. The tennis balls bounce in different ways. - Basketball x 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. Height will be the variable that we will vary. Which surface bounces a ball the highest? 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 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. It would also be fun to explore the effect of different surfaces on the bounce of the bouncy ball. 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 does not store any personal data. changing air density, temperature. 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. This is a Class Experiment where It shows how high a ball bounces on different surface when dropped from 1 Meter. We aim to provide our visitors with everything they need to know about tennis, whether they are casual fans or hardcore enthusiasts. 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. 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 you were to see a ball drop to the ground in slow motion, you would see its shape change dramatically. For the most part, the document is a case study in compulsive precision. There is a chance that you will bounce. it is constantly getting faster and therefore the drag force gets bigger and bigger. Increased energy and movement results in a bounce. Removing the maximum and minimum results and taking an average of the middle three results also provided more accurate results. 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. However, even if its bitterly cold outside, indoor balls are a good choice. Length of Lesson: 30 - 45 minutes. Air resistance exists but does not affect the velocity of the ball significantly. If it bounces up less than .5 meter, then it is more inelastic. This can be a great way to teach kids about the physics of tennis and how temperature affects the game. hypothesis, we predicted that a rubber ball would bounce the highest on rough The International Tennis Federation divides the surface into levels based on speed, with slow being level one and fast level five. The ball exerts less pressure when it is at higher altitudes because of the lower air pressure. One of the hunks of information we found was , v is greater therefore KE is greater by a larger amount). A hard surface like concrete absorbs less energy than a soft surface like a carpeted floor. 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 Make a line graph of your data. As for catching the balls on time, we changed our hand positioning and The drag force increases as the ball goes faster. Then when dropping the ball again eye level will be kept level with the blue tack thus avoiding parallax errors. 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. 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. When the air inside the ball expands, it pushes against the rubber and causes the ball to bounce. 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. Therefore, harder surfaces will ultimately bounce a ball higher. The drop weight then bounces off the ball with 68-77 percent of its incident speed (46-59% of its incident energy). Although catching small balls was an issue, we solved it by getting our better 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. As the ball falls it hits against air particles. use four meter sticks and go right the way up to four meters. 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. Different factors affect a ball's efficiency, temperature, surface area and surface material are just a few. This will be repeated five times, possibly more (for accuracy), for each height and the top and bottom results will be discounted. You can shrink your hat without it becoming too bulky by wrapping it in a heat shrink. We use cookies and those of third party providers to deliver the best possible web experience and to compile statistics. Therefore the coefficient to restitution = 0.7. order to give a fair experiment. Drag is a squared function of velocity and therefore as the ball drops drag increases a greater amount each second. Air pressure will affect the balls fall slightly as the concentration of air particles per cubic meter varies with air pressure. Tennis balls bounce differently in the high altitude and at sea. These cookies ensure basic functionalities and security features of the website, anonymously. Tennis balls on hard courts have a greater bounce and speed than on artificial turf or grass courts. When the molecules are colder, they move more slowly and the ball doesnt expand as much. (2020, November 20). Warmer balls bounce better than cold ones. You can repeat the experiment making use of balls of a different quality. Although we were correct about 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. Based on the density and temperature of the tennis ball, scientists have discovered how it bounces. If you're playing under 68 degrees, it's a good idea to make sure the ball doesn't bounce too much. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Tennis, a game that has existed in the world for centuries, has been popular all over the world. 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 effect of surface on the bounce height of a tennis ball. The first independent variable that will be tested. Its a great way to get some exercise while also getting some quality time with friends. Do you have specific questions about your science project? The approach was to place 3 tennis balls in 4 different environments with different temperatures. didn't catch the ball on time before it went back down to the ground, we would get When the temperature rises above 90 degrees, it becomes extremely dangerous to play tennis outside. The strength of Nadals forehand is what makes him so good on clay. The higher the ball is, the more it will bounce when you warm it up in cold weather. 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. Let the ball bounce until it stops, and then stop recording. Why do golf balls bounce so high on concrete? We then bounced the balls on the surfaces and Drop each ball from a distance of 1 meter onto the surface and record how high it bounces in meters (Example: .46 meters). The aim of the experiment my partner and I performed was to find out which Measuring the height to which the ball bounced on subsequent bounces would be interesting, seeing if h, Less than half the price of our monthly plan. 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 . Hypothesis: if different balls are bounced on different surfaces, then a rubber ball Why Tennis Balls Bounce. = The distance between the bottom of the ball at the top of its arc after bouncing and the ground. I also An investigation into how they impact play on the court. Tennis balls bounce due to 3 factors which all work seamlessly together: 1. In the heat, the molecules are more active, so the ball can bounce higher . Find a clear space to work in. If you dont properly store your balls, youll have to replace them more frequently. Ball trial 1 trail 2 trial 3 average At 2ft, the basketball bounced 15 inches, the tennis ball bounced 12 inches, and the golf. When it reaches Earth, it collides head-on with an . CR can be found out by looking at a graph, the gradient, as a percentage of 1 gives the amount of energy conserved and therefore CRcan be found without knowing v22or v12. 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. 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. For multiple bounces, it's just like dropping the ball again from a reduced height. Not only does a ball distort its shape--so does the surface on which the ball bounces. What was the outcome? Results are presented for a tennis ball, a . When the ball hits the floor and stops, that energy has to go somewhere. We could have improved this Copyright 2002-2023 Science Buddies. At 3ft, the basketball bounced 20 inches, the tennis ball bounced. Try comparing a hot day to a cold day. 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 movement of the air causes the ball to bounce back off the . It should be on a smooth cement surface for optimal ball bouncing. 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. Therefore the height that it reaches is less high. 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. Let's see if physics can explain what happens. 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. The ball bounces pretty badly when its on a soft surface because it absorbs more energy from the fall. The ball weighs exactly 2.5g. We For instance, you can use old balls for the second round of the experiment compared to new balls. The acceleration due to gravity causes the ball to change direction and start moving downwards at stage 2. Keep releasing pressure and repeating the experiment until the ball no longer bounces. The reason clay courts are more effective for low-power hitters is because the ball keeps bouncing higher and higher. With this information, we 2. Cold balls tend to have a bouncier texture. Aim:To find out what affects the height to which a ball bounces. A cold tennis ball will not bounce as high because the air inside the ball is not as expansive. were able to construct a successful experiment. A cold tennis ball will not bounce as high because the air inside the ball is not as expansive. - Sticky tape - 1 roll. 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. The Swiss like to get points over and done with in a short period of time. 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. Then when dropping the ball again eye level was kept level with the blue tack. old and new tennis balls (different surface textures/ages). High bounce ball 2. The Graph on page 23 shows that all of the results were very close together. Experiment 2 is for testing the effect of air pressure. 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. This is because the ball starts with more GPE. The cookies is used to store the user consent for the cookies in the category "Necessary". 1. This would allow one to find the terminal velocity of the ball. 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. It was more reliable to use the middle three results as it automatically discounted any anomalies; assuming two similar anomalies were recorded for one height, if they were then they both would be discounted.
