Bounce efficiency test on various surfaces.

Introduction

Bounce efficiency test on various surfaces.

Introduction.

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

Middle

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.

Method

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.

Grass

Wood

Concrete

Carpet

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

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

    Looking at all the metal results we can see that the graphs are all very similar as this suggests that my results are accurate. Similarly the graphs for wood are same as the results show and equally the experiment was a success as there were no anomalous results that affected the graphs.

  1. What factors affect the efficiency of the bounce of a ball?

    We started at 20cm and then progressed by 0.2m every time until reaching 2m. We did not drop the ball by hand because this would not be avoiding variables like, temperature and height. The Actual results Height from which dropped from (cm)

  2. Physics - Motor Efficiency

    In between the efficiency will vary depending on the mass of the weight. If the mass is high the efficiency will also be high, if the mass is low, the efficiency will be low too. I predict there will be a point where the efficiency starts to decrease.

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

    the ground because less of the energy is used up absorbing the shock and actually misshaping the ball. What is inside the ball actually matters as well. The ball could be hollow and have compressed air in it, like the tennis ball and squash ball.

  2. Investigating the Height and Bounce of Various Balls

    It is difficult to control this factor. Gravity- A larger gravitational force would cause the ball to fall faster and give more resistance to the ball bouncing up. This factor is nearly impossible to change. I have decided to experiment with TWO factors: heat and height. These were the two easiest to control and gave good ranges
