Physics

Obtain two different size balls (bouncy type ball.) This could be a tennis ball, racquetball, ping pong ball, kick ball, etc. Once you have chosen your two balls, drop each ball, one at a time, from the same height. Record how high each ball bounces back up.
NOW; place the smaller ball directly on top of the larger ball. The two balls should be touching. Release the two balls at the same time. The smaller ball should stay directly on top of the larger ball. You may need to practice this until the two balls fall together and perpendicular to the floor. Record how high each ball bounced back up.
Explain, in detail, how the bounce of each ball changed. Explain what happened using the information found in Chapter 7. ( PHY 101)
