The height to which a ball bounces after being dropped provides a measure of how much energy is lost in the collision with the floor or other surface. A small portion of energy is lost to air resistance as the ball is moving, but most is lost in the collision.

1. Trying a number of different balls that you that you may have available, test the height of the bounce using the same height or release for all of the balls tested. Which ball loses the most energy and which is the least?

2. Can you explain why many balls return to a higher height than a marble will? What characteristics of the balls tested give the best bounce?

3. For a ball that bounces several times, does the period (time between bounces) change with each bounce? (Again, recording a video would help tremendously. Make sure your camera is held still and a meter stick or some other object of known height is within the frame, but does not obstruct the motion)

4. Can you predict how the bounce height would change if your release height is doubled? Halved?

5. Try it, observe, measure and record your results. 6. Does the bouncing ball undergo simple harmonic motion? Why or why not?

A ball, dropped onto a hard floor from a height of 2 meters, bounces to a height of 1.8 meters, 90% of the initial height. Each subsequent bounce is 90% the height of the previous one. Find the total distance the ball travels up and down (i.e. after the first collision with the ground it has traveled 2 meters down and 1.8 meters up, giving a total distance of 3.8 meters).
