BounceHeight of a Tennis Ball

Abstract

The experiment seeks to identify whether the temperature and thenature of the surface used will influence a bouncing tennis ball.More specifically, it will depend on two experiments with the firstone evaluating if temperature plays a major part while the secondexperiment will highlight the effect of the surface on the bouncingtennis ball. It will also analyze the data from the experiment toprove that the hypothesis heated tennis balls and those tennis ballsbouncing on the hard court both will reach higher heights.

At times,various activities might need the bouncing of tennis balls, but theparticipants will proceed without acknowledging factors thatinfluence the bouncing of tennis balls. Some of these factors includethe temperature as well as the surface that the tennis ball will bebouncing on. In this experiment, two procedures will prove whetherthe temperature and nature of a surface are influential in thebouncing of the balls. Evidently, such knowledge is essential inthose that might often use the tennis balls for various activities inthe community.

  1. Materials and Methods

    1. Materials

The experiment will need the presence of four tennis balls, a clamp,a measuring ruler, a table, heater, freezer, hard court and the grasssurface too.

    1. Experimental Procedure

More generally, the experiment had two experiments that all aimed atdetermining if the temperature and the nature of a surface willinfluence the height a bouncing ball will reach when released on thetwo surfaces.

    1. Experiment One

The first experiment had a first tennis ball being heated for twentyminutes while second was frozen for a period of an hour as the thirdone remained at the room temperature. After that, each of the tennisballs was dropped from a height of 200cm. The steps were repeated twomore times in order to achieve the accuracy needed for theexperiment. Later, the results for each ball were recorded includingthe multiple times the heated, frozen and normal tennis balls weredropped.

    1. Experiment Two

The second experiment will evaluate the impact of the nature ofsurface on influencing the height a tennis ball will bounce whenreleased from a point above. The experiment will need the only onetennis ball that will be released on the grass surface and the hardcourt. The presence of the measuring ruler will help in identifyingthe height the tennis ball will reach when released on a grasssurface. Other than that, the procedure is repeated with the ballbeing dropped two more times before determining the accurate resultsneeded. After the first steps, the same steps are repeated but usingthe hard court in this case.

    1. Analytical Methods

Evidently, the use of heating, freezing and normal temperature of thetennis balls help in reaching diverse outcomes. The use of thedifferent surfaces also determines the impact of the surfaces in thebouncing balls as well.

The findings of the first experiment show that the temperature playsa major role in determining the height that a bouncing ball willreach. The heated tennis ball ended up reaching an average higherheight of 106.59cm as the frozen tennis ball reached the averagelowest of 53.38cm. The one that was at room temperature bounced tothe average height of 93.29cm instead. From the data, the sole reasonfor the difference of the heights the bouncing balls reached arisesfrom the pressure gas within the tennis balls. The equation p=rRTwith “p” being pressure, “r” the density, the “R” isconstant related to the gas while the “T” represents thetemperature (Stewart, 2015). More specifically, as the densityremains constant and the temperature keeps rising, it will amount tohigher pressure as well. A decrease in the temperature will result inthe reduction of the pressure and make the ball smaller and alsobouncing a lot lesser than expected (Myers, 2006).

The data reveals the way that tennis balls behaved on the differentsurfaces. The ball bounced to an average height of 42.33cm while onthe grass surface as it reached to 55cm while bouncing on the hardcourt surface. The cause of the difference in the two surfaces arosefrom the way each of the surfaces had different abilities inabsorbing kinetic energy (Harriman, 2012).

  1. Conclusion and Future Works

In conclusion, the data proves that temperature as well as a type ofa surface all help in influencing the height that a bouncing ballwill reach. In this case, activities that involve the use of tennisball should keep in mind the weather conditions since it willinfluence the temperature that will also affect the bouncing of thetennis ball. The surface also has an impact on the kinetic energythat will make the tennis ball behave in a way that will be muchnormal as well. The future of the research will be based on otherfactors that might influence the bouncing of the ball. In theprocess, it will be much easier to determine other factors such asthe age of the tennis in influencing the height that the bouncingball will reach.
