# I am going to do an experiment on how high a squash ball bounces at different temperatures from the same height.

Extracts from this document...

Introduction

## Squash balls

### Introduction

I am going to do an experiment on how high a squash ball bounces at different temperatures from the same height.

Middle

Apparatus

### Method

1. Set apparatus.
2. Put ball in beaker.
3. Wait till temperature reaches 100°C.
4. Use tongs to take ball out of water.
5. Drop ball from a height of 1m.
6. Put ball back into beaker and wait for five minutes.
7. Repeat process 2 more times.
8. Lower temperature to 80°C and wait for five minutes.
9. Take ball out and drop from 1m.

10.Repeat as above for temperatures-60°C, 40°C, 20°C and 0°C.

12. Put results into a table.

### Fair test

I am going to use the same ball and drop it from the same height.  The only thing I am going to change is the temperature.

Accurate

I repeated the experiment 3 times, then took an average result to remove any odd results.

### Number and range

I have chosen this range because it is easier to prove the height that the ball bounces.

Safety

Conclusion

°C the ball bounced at 28cm, 26cm and 28cm, and at 80°C the ball bounced at heights of 59cm, 58cm and 57cm.  My evidence is good enough to support my conclusion because it is accurate and reliable, it was also a fair test and there was a good number and range.  This means that I could use my results to look and test my theory.  I am going to extend my findings by heating up a cricket ball.  I am going to explain an experiment that

could measure the same thing in a different way e.g. instead

of measuring the height of the bounce at different temperatures I am going to find out the distance of the bounce against a wall with the same force and with different temperatures.

1. ## Investigate the effect of temperature on the bounce height of a squash ball.

The bounce height for all the temperatures will be much less than the original dropping height because energy is lost converting elastic potential energy into kinetic energy. Risk assessment To ensure a safe investigation I will make sure that nobody is around our working area so nobody could possibly get hit by the ball.

2. ## The effect of drop jump height on spinal shrinkage.

The implications of which can be readily explained in that the spine is at its most vulnerable in the morning (Reilly et al., 1984). Lying supine throughout the night relieves a proportion of the gravitational pull upon the spine, enabling the spinal column to return to its normal length.

This scatter graph shows pupils' IQ and average Key Stage 2 results. It shows a strong positive correlation which therefore means that the greater the IQ, the greater the average Key Stage 2 results are. The R� of the trend line relates to the how the average Key Stage 2 results are effected by the IQ.

I think this because the ball will reach its terminal velocity and will be hitting the surface at the same velocity every time because the weight and the resultant force (air resistance in this case) will be equal. Below this particular height I think the bounce of the ball will

1. ## What factors affect the bounce height of a squash ball

Therefore all this GPE can be converted into kinetic energy, allowing it to bounce higher. As well as this, when a ball is dropped from a higher height, the ball is compressed more when it comes in contact with the ground, and therefore the compressed air can again make it bounce back higher.
