A ball is dropped from rest and its height and speed are recorded using a Wireless Motion Sensor. The ball’s potential energy and kinetic energy are calculated at various points during the ball’s fall.
The total energy of the ball is examined throughout the fall to determine if there is any change. Balls of different sizes are used to vary the amount of air friction, so that students can see that energy is not conserved when friction is appreciable.

- Kinetic energy of a falling ball
