1N30.10 Collision Balls (Newton's Cradle)
Concepts
Conservation of momentum, conservation of energy
Overview
When the first ball is lifted and released, it collides with the row of stationary balls. All its momentum and energy are transferred through the balls to the last ball on the row. If you lift and release n balls, n balls will carry the same momentum and energy after the collision.

Equipment
- [1] Newton's cradle
Script
- Pull one ball at the end of the row sideways and release it.
- Pull two balls at the end of the row sideways and release them.
- Other variations include pulling 3 or 4 balls at a time or pulling balls on both sides simultaneously.
