Why does a squash ball bounce higher when it is warmed up?

Science Coursework: Squash Ball Investigation


To find out “Why does a squash ball bounce higher when it is warmed up?”


I predict that for this experiment the higher the temperature, the more the ball will bounce. I put this down to the temperature is raised, the particles inside will gain energy therefore the higher the ball will bounce.


For this experiment I will use the following equipment to do this experiment: -

  1. Beaker
  2. Bunsen burner
  3. Splints
  4. Tripod
  5. Gauze
  6. Thermometer
  7. Squash Ball
  8. Paper Towels
  9. Meter Ruler

10. Tongs

11. Stop Clock

12. Safety goggles.


Choose one yellow spot squash ball. This will be used throughout the experiment to ensure that the ball is made of the same rubber and same size. The experiment will be carried out on the hard floor tiles of the science laboratory. The area will be clean to ensure there are no irregularities on the surface.

I am going to work out pressure and predicted hang time using the following formulas.

This is how to work out pressure; P1 is Pressure 1, which is always 1. T1 is Time 1 and T2 is Time 2.  

                                                                               This number changes as you

                                                                               work out P1, P2 P3 etc.

                                                                                Eg. P1 = P1, P2 = T2 etc.

P1 x T2


To work out predicted hang time you use this formula. In this formula P1, P2 etc are Predicted hang time.

                                                                               This number changes as you

Use a different way of timing the balls impact to the ground; a touch sensitive timer mat would work well.I would try different surfaces on which the ball lands on, this could be thought of as another variable I could develop.

If I were to do this experiment I would change the temperatures to smaller differences i.e. 273 Kelvin, 278 Kelvin etc. to see if I could find an ideal temperature that had a good enough ‘bounce’ to help develop work into elasticity of the balls material.

 If I were to develop this experiment further I would test elasticity. To test this I would experiment with a range of different squash balls. I would cut them into equal narrow pieces and use a Newton spring to test how much the piece of squash ball could hold and how long it would take to reform back to its original shape, for this I would use a Newton spring and stop clock.

All in all I think I conducted myself well on this experiment and have learned a lot.

  1. The Bouncing Ball Experiment

    would be able to put numbers into them, and form conclusive results. Two metre rulers were stood on top of each other in front of the 50cm mark and held firmly in place by two people so that they were not slanting or leaning against the staircase.

  2. physics of the bouncing ball

    At 90cm the tennis ball hardly changed in terms of bounce height, it bounced up 0.8cm less than the previous bounce height at 100cm. With all of the other types of ball there was a noticeable change. The rounder ball actually bounces nearly 2cm higher.

  1. Physic Coursework - Squash ball experiment

    I decided to drop the ball from 4 difference heights (0.40m, 0.80m, 1.20m and 1.60m). The experiment is going to be repeated 3 times for an accurate average of the height of the bounce. Every other variable will be kept the same.

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

    Set up the equipment as shown on the diagram. 6. First test will be done at room temperature, which is about 200c. 7. Someone will be ready to check where exactly it bounces. 8. Once it has bounce you will quickly record the height and note it down. 9.

  1. Investigation on the factors that affect the bounce of a ball.

    Also energy is used up in over coming the air resistance. The energy of impact can be split into sound energy, heat energy or light energy (spark) in the case of very heavy balls (for ex. Iron balls striking iron plate surfaces).

  2. What Factors Affect the Bounce of a Squash Ball.

    The air inside the hollow, airtight ball is trapped. When air is heated the distance between the molecules increases, and therefore the amount of pressure within the airtight ball increases. Quite how this could affect the height of the ball would require a lot more detailed research. 2. The molecules of rubber which the ball consists of may become

  1. What affects the bounce of a squash ball?

    Different types of squash balls have different resilience (research4). If a ball has a higher resilience (can store a lot of energy under deformation) it can bounce higher (research2). Different balls show their resilience by the colour dot they have.

  2. The Bouncing Ball Experiment

    original idea for five repeats was proved wrong, three repeats are sufficient and the starting drop height was too low (also with time we had, we could not take readings every 10 cm as it would be too time consuming, so 15cm seemed a more suitable unit to go up in).
