Example 3
easyName the energy transformations when a ball is thrown upward and comes back down.
Solution
- 1 Going up: kinetic energy converts to gravitational potential energy as the ball decelerates.
- 2 At the top: all energy is potential energy (momentarily at rest).
- 3 Coming down: potential energy converts back to kinetic energy as the ball accelerates.
Answer
Energy transformations are central to understanding physics. The total mechanical energy remains constant (ignoring air resistance), but it shifts between kinetic and potential forms.
