# Investigate the difference in energy transfer when dropping a squash ball from different heights.

Extracts from this document...

Introduction

Investigate the difference in energy transfer when dropping a squash ball from different heights. Squash Ball Experiment Important Variables: Height Of Drop Temperature of Ball Material of Ball Acceleration Due To Gravity Mass Air Resistance Introduction: I will investigate how energy is transferred when dropping a squash ball, and how the height the ball is dropped from effects how much energy is transferred. The types of energy I will be looking at are: - GPE (gravitational potential energy) - This is at its most when the ball is being held. To work out an object's GPE we use the equation: - GPE=Mass (kg) x Gravity (n/kg) x Height (m) So the GPE of a squash ball at a height of 2 metres, when it's mass is 0.237kg (23.7g) and Gravity is always 10n/kg is: 0.237 x 10 x 2 = 4.74 j Kinetic energy - this is when the ball is moving i.e. falling through the air; we can work it out using the equation: - Kinetic energy = 1/2 x mass x velocity? ...read more.

This will be done by dropping the squash ball from five different heights and recording the height bounced. The amount of energy transferred will then be worked out by: - - Working out the squash balls GPE in relation to the height it was dropped from - Subtracting from the GPE the MGH (mass x gravity x height) of the height to which it bounced, for example Balls GPE= 0.237 x 10 x 2= 4.74 MGH of height bounced= 0.237 x 10 x 0.54=1.2798 So the energy transferred would be: So 3.4602j of energy has been transferred into heat and sound. As I am using two different squash balls (one with a white spot and one with a red spot) I will repeat this process on both sets of results for the five different heights. Prediction I predict that as the balls dropping height increases; the energy transferred will also increase Conclusion From my results I can conclude that as the temperature of the ball rises the height of the bounce gets higher. ...read more.

Conclusion

I had one anomalous result even after an average over five measurements. I can say that looking at my results when I repeated results they were quite close together. I think that I did the experiment quite well although I found it hard to spot where the ball bounced too. This is why I did an average over 5 measurements. To improve the experiment I would need to use specialist equipment like lasers so I could be sure where the ball bounced too. Ways in which I could extend this experiment are to use a different kind of rubber in the ball so that it doesn't melt at such a low temperature this way I could carry on to see whether the kinetic theory is still right at higher temperatures. Also I would like to see what happened when the ball was at 0 degrees Celsius. 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 (Absolute Zero) ...read more.

4 star(s)

* If I use different surfaces for the ball to bounce on, I may get different results because different surfaces absorb energy better than others. * If the temperature increases, then in theory the bounciness should increase. This is because the atoms have more energy so they'll move faster; they'll have more kinetic energy inside the ball.

2. ## The Bouncing Ball Experiment

What I can do with my Results: When I have got a set of results, I can use them to prove or disprove my hypothesis, relating GPE with drop height and bounce height with drop height. I can exclude any obviously anomalous results from my results.

1. ## Investigating the relationship between drop height and bounce height when a ball is dropped.

This is a shame, because I would liked to of added them to my report as it would have given me a wider range of results. But due to lack of time I was un-able to do this and therefore time was against me.

2. ## 'The Effect of heat on a Squash Ball'.

By using my knowledge on atoms I know that as the temperature increases the atoms in the ball vibrate more. This means that when it hits the ground the atoms push each other away forcing the ball to bounce higher.

1. ## The Bouncing Ball Experiment

The more kinetic energy the ball had to begin with, the more it will have stored now and the more it will be able to keep on rising before its energy runs out. With the height it gains in the bounce, it again has gravitational potential energy to come down

2. ## physics of the bouncing ball

I will drop the balls at intervals of 10cm starting at 100cm down to 10cm. I will measure the drop height and bounce height from the bottom of the ball. I will then work out the average bounce height for each ball from each height and plot them on a graph.

1. ## how and why temperature affects the bounce of a squash ball

For something to bounce with maximum efficiency it must lose as little energy as possible during its collision with the surface. Energy will be lost during the balls collision with the surface. This can happen if the balls kinetic energy were transformed into another form during the collision.

I have chosen to vary this factor because it is easier and quicker to construct within the time constraints I had. Before doing my final experiment I will be constructing a few preliminary experiments to help me understand more about the range of readings I should use, the surface of
