COLLISION BALLS


APPARATUS
collision balls 202-14-D


DESCRIPTION
This set of nine aligned balls with equal masses on bifilar supports are used to show elastic collisions.  Pull aside N balls and release.  N balls will swing up on the other side, drop back down, and then the process repeats.  This is consistent with conservation of momentum and energy.

NOTES

Make sure balls are truly aligned.
