Introduction

What affects the bounce of a squash ball?

Aim

What affects the bounce of a squash ball?

Constant

Air Resistance

The experiment will be done in the same area so assume air resistance is kept constant.

Mass Of ball

Mass of ball is made of a particular type of mass as given by the world governing bodies

Input Force

This will be constant as simply dropping the ball will mean no force is being used.

Surface Bounced on

Difficult to measure so lab floor will be used constantly.

Height

Dropped from 2 metres.

Material

Material of ball is made of a particular type of mass as given by the world governing bodies

Input

Heat/Temperature

The variable I will test.

Output

Height Bounced

The results I will measure

Predictions and Scientific Understanding

I predict that the hotter the squash ball the more it will bounce.

A squash ball is made up of a rubber sphere containing air. The air molecules in the ball will speed up as you heat it. Heat energy is converted to kinetic energy. The speed the molecules hit the side with increase, which means the momentum of the molecules is increased. Newton’s 2nd

Middle

Goggles because of Bunsen burner

Drop Vertically

Away from bounce zone

Use tongs to handle squash ball because of high temperatures.

Observation

As the temperature increases the bounce height increases.  I have chosen to do my readings at 10 intervals.

Procedure

I heated up the ball by placing it in a beaker of boiling water. I measured the temperature each time. I measured temperature of water to determine the temperature of squash ball.

To get the ball at an accurate temperature I submerged the entire ball. The ball was taken out of the water as quickly as possible. I assumed heat loss each time was approximately 30 seconds.

Rubber isn’t a good heat conductor so the ball was kept submerged for a period of 2 minutes.

The ball was held at the 2-metre mark and then dropped. This was because from the preliminary readings I found that I couldn’t get adequate readings by dropping the ball from 1 metre. The height bounced was recorded by the naked eye.

Conclusion

To improve the experiment I would need to use specialist equipment like lasers so I could be sure where the ball bounced too as the surface I bounced it on, the lab floor, was in some places and I couldn’t accurately control where it bounced as I made sure no input force was used to drop the ball.

Another better way would have been if I used a squash ball made of a special material which could withstand higher temperatures so I could have been able to carry on my experiment to see when the graph actually levels off.

Also I would like to see what happened when the ball was at 0 degrees Celsius. However that would have meant using ice, which is a variable, I don’t think I could have accurately kept at a suitable level to measure.

I would like to do this to see whether the atoms still vibrated causing the ball to bounce. If it did I would like to carry on getting lower and lower to see whether there was a temperature where the atoms no longer vibrated (Which in theory is Absolute Zero which has never been reached).

    measurement that the ball actually rebounded back on may have been interpreted incorrectly hence leading to the anomalous results in the graph * Another reason for this could be that the squash ball was not put back into the water for a short period of time when attempting the second or third drop.

    Tables 1.2 and 2.2 contain the raw and processed data for the second spring. This spring is very flexible and its coils are not extremely close to each other. This spring was longer than the first spring with a length of 14.8cm and this was because of its coils not being so close to each other.
