Investigation " How the Temperature of a Squash Ball affects the Bounce

Extracts from this document...

Introduction

Investigation – How the Temperature of a Squash Ball
affects the Bounce

Aim: Investigate if the temperature of a squash ball affects how high the squash ball bounces.  Then calculate the speed of the bounce.

Hypothesis: The higher the temperature of the squash ball then the higher the bounce which means that the speed of the bounce increased.  

Variables:
MV – temperature of the squash ball (degrees Celsius)

RV – bounce of the squash ball (cm)

CV – ball, meter stick, stopwatch, kettle

Equipment:

  • Calculator                        - Meter stick
  • Kettle                                - Safety mat
  • Beaker                         - Thermometer
  • Goggles                        - Tongs
  • Stop watch                        - Squash ball

Procedure:

  1. Firstly set up all the necessary equipment and then pour water from the tap in the kettle and switch on the kettle so that the water begins to boil.

To calculate the speed of the squash ball the calculation is speed = distance
                                                                          time

I then took the height that the squash ball bounced and divided it buy the average time (0.85 seconds).

Speed = 6cm

I then rounded the number up to two

Conclusion:

In conclusion my hypothesis which was “The higher the temperature of the squash ball then the higher the bounce which means that the speed of the bounce increased” was proved by the results above because when the temperature was 60ºC the squash ball bounced 17.4cm and the speed of the squash ball was 20.47cm/s whereas when the temperature was 30ºC the squash ball only bounced 6.5cm and the speed of the squash ball was 7.64cm/s.  This is an example which shows that the temperature of the squash ball does affect the bounce and the speed.  

If I was to do this experiment again then I would make the experiment more accurate by repeating the experiment for each temperature several times and then take the average so that my results would be more accurate.

    It has also been shown on a sketch, that each following bounce is shorter (in height) as the ball was wasting part of its energy, while converting mgh (Potential energy) into (Kinetic energy). The fact that the graph doesn't go through the point (0,0) shows presence of the systematic error.
