Description

Used for two dimensional collision experiments. A simple but dependable apparatus for demonstrating elastic and inelastic collisions in two dimensions. The impact points of the ball on the floor are recorded with carbon paper. Because the fall time to the floor is constant and easily computed, horizontal distances can be converted into velocities, permitting the momentums to be computed.

The set consists of a curved ball track with mounting hardware, two 12 mm steel balls, one 12 mm glass ball and a hollow 25 mm wooden ball. A weight and plumb line are also supplied.
