Elastic Collision
A collision in which objects bounce off each other without losing kinetic energy.
Power
The rate at which work is done or energy is transferred.
Work
The energy transferred when a force is applied over a distance.
Mechanical Advantage
The ratio of the output force produced by a machine to the input force applied to it.
Simple Machines
