This Physcast follows on from the first momentum tutorial (Rathkeale Physics - Momentum 1). It involves two stationary ice skaters pushing apart on ice. Conservation if momentum is used to determine the velocity of one of the skaters.

A brief introduction to momentum and conservation of momentum. This tutorial includes a problem involving the collision of a locomotive with a stationary carriage. The two objects stick together after the collision and the combined velocity is determined using conservation of momentum.
