Newton's Cradle - 1N30.20

- Raise a ball away from the others and release it- It collides with its neighbor.
- The momentum of the ball is transferred through the system.
- The ball on the other end reacts accordingly.
- Repeat the process with two balls, or three, or four.
- This demonstrates conservation of momentum in a collision involving several bodies.

Velocity Amplifier using Stacked Disks – 1N30.62

- Four discs (1 5/8", 3 1/8", 5", and 8") are placed on top of each other such that they stand vertically.

- The four discs are also confined to the vertical plane.

- Raising and releasing two discs will cause the smallest disc to bounce a few inches.

- Raising three will cause the smallest disc to bounce out of the apparatus a few inches.

- Raising and releasing all four will cause the smallest disc to fly many feet into the air.
