Curved ball track
1997.00-.90
Used for two dimensional collision experiments. A sim-
ple but dependable apparatus for demonstrating elastic
and inelastic collisions in two dimensions. Because the
fall time to the floor is independent of any initial horizon-
tal velocity, the horizontal displacement can be conver-
ted to a relative velocity, permitting the momentum to be
computed. In order to obtain the full benefit from this
experiment, students should be familiar with vectors.
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.
