This inexpensive apparatus is a rich source of data for studying conservation of momentum and conservation of kinetic energy in collisions. -- It is also used to compare elastic and inelastic collisions. A curved metal track and an adjustable target support form the core of the unit. It is supplied with two steel balls, a glass ball, and a plumb bob. It requires a C-clamp for mounting on a table.
