This physics video provides a basic introduction into elastic collisions. It explains how to solve one dimension elastic collision physics problems. In an elastic collision - two objects usually bounce off each other. Conservation of momentum and conservation of kinetic energy occurs during an elastic collision. This video provides the equations and formulas to solve a typical elastic collision with two missing / unknown variables.
