Investigating the Bounce of a Squash Ball

Extracts from this document...

Introduction

Investigating the Bounce of a Squash Ball

In this investigation I will be measuring the bounce of a squash ball and record the results in a table and on a graph with an aggression line.

There are a number of factors which could influence the bounce these include the following;

Type of surface

Angle of surface

Angle at which Ball is dropped

Material of Ball

Mass of Ball

Diameter of Ball

Temperature of Ball

Pressure of Air in Ball

Air Resistance

Height of Drop

Force used to Drop Ball

Acceleration Due to Gravity

Temperature of the Ball

To make the test fair, certain variables have to be kept fixed and at a constant otherwise the results would not be right and a conclusion cannot be drawn from the anomalous results.

Force used to Drop Ball

According to how much force is applied to drop the ball, it will bounce higher or less. If suitable equipment was available in the school, students may be able to automate the “dropping of the ball” process so that a machine drops it from a given height. This would eliminate the possibility of human error, as we would not be able to drop the ball with an equal force each time making the results unfair.

Diameter of Ball

A larger ball with a larger diameter will have a bigger surface area meaning that when it hits the floor, more of its area will be in contact with floor at impact and this will affect its bounce back height. For this reason, to make the test fair, the same sized ball with the same diameter will be used.

Type of Surface

Different surfaces have different smoothness and changing the surface half way during the experiment will make the test unfair as some surfaces according to their smoothness will allow a nice, neat bounce whereas other surfaces will alter the bounce due to indentation in the surface and bumps etc. To make the test fair, all testing will be done on a bench surface throughout the experimenting procedure.

Angle of Surface

The angle of the surface at which the ball is bounced on will affect how it bounces back up and how far too. To overcome this, a surface, which is horizontally straight, will be chosen to experiment on. This same surface will then be used so that there will not be any change in its angle making the test fair.

The graph of the average results is over the page.

The results are what I expected them to be, the higher the temperature of the ball the higher the bounce, my hypothesis was correct. According to my results if the ball had been 80ºC then the average result would be a lot higher.

Evaluation

If I had measured the second bounce I would have found a difference as the energy would have been lost to sound and through the ground.

As the temperature raises the speed increases as does the pressure causing a greater bounce. The ball becomes deformed as it hits the ground as it changes direction. If I had time I would have done a second experiment and changed the height it was dropped from. I would expect the height of the first bounce to increase as I increased the height it freefall from. I also could have changed the mass of the ball while I changed the temperature to see if both have an effect on the bounce.

I believe the experiment was a success as I have gained no anonymous results in the table above.

    I will make sure that the bottom of the squash ball is parallel to the 100cm mark on the ruler. (See below). I will repeat the entire experiment described above, in order to check my results, and to identify and eliminate any anomalous readings.

  2. What factors affect the bounce of a squash ball?

    height of the squash ball increasing when the temperature of the ball also increases. The reason for this is as follows: When the ball is heated the temperature increases and the average speed of the air molecules inside increase, therefore the pressure also increases and the ball becomes incompressible.

    We have already known that squash ball gets more elastic as its temperature increase. But what effect will it do to the average force act on the ball when it comes to impact when temperature increases? By knowing that, we can find out the rate of change of average force of impact when temperature.

    To increase the reliability and accuracy of the experiment I checked and adjusted the apparatus every time the trolley did a run so the apparatus were always set up properly and therefore always give the correct reading. The measurements of the runway such as its width and length were measured to the nearest centimetre using the metre ruler.
