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: (PIRA 1N30.10)
EQUIPMENT: Collision ball apparatus, as photographed.
SETUP TIME: None.
