Bounce efficiency test on various surfaces.


This is an experiment to see how high a ball will bounce on the different surfaces. We will use 5 different surfaces – concrete , wood , grass , lino and carpet material.To do this we must use the same size ball to reduce excess drag and drop it from the same height each time . That is one variable (surface type) , the other is ball material – tennis ball , golf ball , bounce ball , cricket ball and baseball . We would drop it from the same height each time . We try bouncing the ball from

If I changed the ball it would bounce at :

          70% with a tennis ball

          30% with a base ball

          20% with a golf ball

          35% with a cricket ball

          80% with a bounce ball

as a soft ball would spring back but lose lots of energy through sound , heat , and change of shape. I have chosen to use surfaces as my variable.


We will by eye drop a ball from a definite height (from the same person each time) onto a different surface at least 3 times, we then observe how high it rebounds , take the results , then insert and compare them in a table.

Height bounced (cm)

Average (cm)

Efficiency (%)






To work out the efficiency percentage we divide height bounced by height dropped then multiply the answer by 100.

  2. What factors affect the bounce height of a squash ball

    The molecules, with more kinetic energy, have more frequent collisions with other molecules and the walls of the squash ball, thus pressure is increased. The increase in pressure means that the squash ball will bounce more. A change in temperature would change the outcome of the experiment dramatically, so I am conducting the experiment at room temperature.

    Tides are the vertical and periodical oscillations of the sea caused by the gravitational forces exerted upon the earth by the sun and moon. The highest zone on a shore is the splash zone; it's splashed by spray but not covered by the sea.

  2. Study how balls bounce, specifically focusing on how drop height affects the rebound height. ...

    They all have different advantages and disadvantages. The textures of the balls surface matters as well; the golf ball and squash have a slippery smooth surface this will create less drag therefore less air resistance. The tennis and foam both have quite rough or not very aerodynamic surfaces.

  1. Investigate and test a strain gauge sensor using different materials.

    While compensated gauges reduce the thermal sensitivity, they do not totally remove it, but a low P.D does not crate a significant increase in temperature. There could be random errors, noise that could affect the results but to prevent this from happening I will repeat the experiment several times.

  2. In this investigation I will conduct a number of experiments and collect a number ...

    This means that when it is just about to hit the ground it will have more kinetic energy the higher it is dropped from. Again I think that the hollow balls that are hard will bounce higher (see prediction above).

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

    This may again be due to the molecules in the squash ball again really starting to speed up as the temperature goes from a warm state to a hot state. This shows overall that there is a definite link between the bounce height and the temperature of the ball and
