ID Code: C7-25
Purpose: Show that a larger impulse is imparted by an elastic collision.
Description: A vacuum mud ball at the end of a rod is held horizontally and released so that it swings into a wooden block. The vacuum mud ball is replaced by a superball with the same mass, and the experiment repeated. Q: In which of these cases will the wood block be knocked over? A: The superball knocks over the wooden block because it bounces back, imparting more momentum to the block.
Availability: Available
