1N30.10: COLLISIONS OF BALLS - EQUAL MASSES

PURPOSE: To demonstrate conservation of energy and conservation of linear momentum in multiple elastic collisions.

DESCRIPTION: To start, hold one, two, three, or four balls to the side and release. Symmetric oscillations result from conservation of energy and conservation of linear momentum in the collision sequence.

SUGGESTIONS: For best results make sure balls are well aligned.

REFERENCES:

EQUIPMENT: Collision ball apparatus, as photographed.

SETUP TIME: None.
