Answer:
1. A rubber ball is dropped and bounces back up. The ball has both kinetic and potential at C.
2. A rubber ball is dropped and bounces back up. The ball's potential energy is at its maximum at A.
3. Which best describes the changes in energy as a child goes down a slide? potential energy decreases and kinetic energy increases
4. potential energy decreases and kinetic energy increases? As an object falls its potential energy decreases, while its kinetic energy increases
