Note whether the ball and surface showed more of an elastic or inelastic collision. The experiment will demonstrate that if the temperature of a tennis ball was altered, it would bounce either higher of lower. More thermal energy is also produced. The balls bounced higher on the concrete The tennis balls bounce in different ways. The ball has reached its terminal velocity and cannot fall any faster (unless dropped in a vacuum). Why does Rafael Nadal do so well on the clay? Balls bounce up to 5 . concur, which was catching the small balls. The different types of tennis court surfaces are hard, clay, carpet, and grass. 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. Improvements that could be made to the experiment if future work was to be done: To provide additional relevant evidence I would conduct further work as follows; I would like to conduct the same experiment in a vacuum. This cookie is set by GDPR Cookie Consent plugin. What do you think this means about your results? Measure from the bottom of the ball. Not The drop weight then bounces off the ball with 68-77 percent of its incident speed (46-59% of its incident energy). For multiple bounces, it's just like dropping the ball again from a reduced height. 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. Such an impact compresses the ball 1.4-1.6 inches, or about 54-62% of its diameter. 15 inches, and the golf ball bounced 26 inches.

Use the paint and a tape measure to make a series of lines on your roll of paper. For a falling object the Coefficient to restitution (CR) is equal to the velocity squared as the object is travelling at as it leaves the floor (v22) divided by the velocity squared as it hits the floor (v12): If dropping a ball in a vacuum all you need to know in order to know how high the ball will bounce to is h1 and CR. Obviously, a ball won't bounce as high on carpet. surface bounces a ball the highest. There are more than 160 different types of tennis surfaces. discovered that there is a handful of information that would assist my partner and I You can repeat the experiment making use of balls of a different quality. By clicking Accept All, you consent to the use of ALL the cookies. If you're playing under 68 degrees, it's a good idea to make sure the ball doesn't bounce too much. These cookies ensure basic functionalities and security features of the website, anonymously. What affects ball bounce? It does not store any personal data. 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. 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. High bounce ball 2. Why do balls bounce higher on different surfaces? After the ball reaches terminal velocity, no more GPE is converted into KE is the ball cannot get any faster. - Pencil x KE = 1/2mv where m = mass and v = velocity, 1/2mv = mhg - thermal energy (lost as a result of drag). You can also try using a hair dryer to heat the ball up. This is because it is easiest as the figure read of the meter rule is the result. The ball moves upwards, reaching stage 1, i.e., maximum height, and its velocity is momentarily zero. How can you measure the height a ball bounces? The Graph on page 23 shows that all of the results were very close together. Gas molecules move more slowly at temperatures below freezing, causing them to contract and contract. SCIENTIFIC Method Aim & Hypothesis Method Variables Risk Assessment Results Conclusion & discussion 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. Use the pressure gauge to release some of the air pressure from the ball. It shows that heights were recorded that exceeded the height that the ball would have reached had it been dropped in a vacuum. The bouncing of a tennis ball on a tennis court surface is analysed by making several simplifying assumptions about the physics of the interaction. This also proves the accuracy of the experiment. You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use. If it bounces up less than .5 meter, then it is more inelastic. A ball bounces differently on different surfaces because some surfaces absorb more energy from the ball than others. 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. 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. 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. Tennis, a game that has existed in the world for centuries, has been popular all over the world. Determine how high the ball rebounds on its first bounce. As the ball falls to the surface it has kinetic energy. Then when dropping the ball again eye level will be kept level with the blue tack thus avoiding parallax errors. This is called the relative speed. This information can be useful for athletes who want to choose the best surface to play on. Is it a straight line? It will not bounce to high if it is heavy. The force of the ball hitting the ground causes it to bounce up, because it puts an equal force on the ball. It provided me with five repeats so that the maximum and minimum results could be discounted and a reliable average could be taken. When it reaches Earth, it collides head-on with an . Record the new pressure reading in your data table and repeat steps 4 and 5. Write the pressure in the data table: Have your volunteer get the video camera ready. 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).

Bending Plant Roots with Gravity Lesson Plan Introduction. 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. This means for the ball to reach terminal velocity the drag force has to be bigger and for the drag force to be bigger the ball has to fall faster (so that more air particles hit the ball every second). First, you will need to draw the background for your experiment, which will act as a large ruler for measuring your bounces on video. The steel has a lot of bounce power due to its better storage of energy. With this information, we 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. The ball did not reach terminal velocity however as it did not have enough time to accelerate to its terminal velocity. Experiment 2 is for testing the effect of air pressure.

During the research fraction of the experiment, it was The cookies is used to store the user consent for the cookies in the category "Necessary". . Answer (1 of 2): Some surfaces absorb more energy than others do. But what makes a ball bounce? Why does a tennis ball bounce higher on concrete? This website uses cookies to improve your experience while you navigate through the website. Then when dropping the ball again eye level was kept level with the blue tack. Therefore the ball ends up with more GPE, , assuming g and m stay constant, results in an increase in m g h, , assuming g and m stay constant, results in a decrease in m g h, As the ball is accelerating due to gravity, at 9.81m/s. Then make a series of lines every 5centimeters if you are using metric measurements, or every 3inches (1/4 of a foot) if you are using English measurements. The colder, the lower the ball bounces, and vice versa. Materials 1. This is due to an inelasticity in the energy lost when the ball collides with the ground, as well as the fact that the ball bounces every time it is hit. The reason balls bounce is quite advanced science. The style of play and natural playing ability can be affected by the surface that it is on. Apparatus:Clamp stand, meter rule 2, table tennis ball, desk. Decide on a height you want to drop the balls from . Once the drag force equals the gravitational force all forces are equal and acceleration stops. bounces the highest on 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. 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. . . A cold ball typically has less bounce than a warm ball. However, you may visit "Cookie Settings" to provide a controlled consent. Experiment Click the following buttons to skip to a page.
