- Purpose: Demonstrate properties of gravitational potential
energy.
- Balls start moving and end with identical velocities, but ball on longer track traverses path more quickly.
- Prove that balls end with identical velocities by showing they fall the same distance from the end of the track. Use carbon paper to show location of impact.
- Located in L02, section B2

- Purpose: Demonstrate properties of gravitational potential
energy.
- Though balls start and end at same height and with same velocity,
ball on longer track traverses path more quickly.
