The amount of available **kinetic energy** (KE) depends on the objects mass and speed. The greater it's mass and the faster it's going, the bigger the KE will be.

## Calculating kinetic energy Edit

The equation for kinetic energy is KE = ½ mv2

An example of calculating KE is:

A car has a mass of 1500kg and it is going at an average of 15 m/s

What is it's KE?

KE = ½ mv2

KE = ½ x 1500 x 15²

KE = 750 x 225

KE = 168750
