Kinetic Energy (Also seen in GCSE Physics 2)

Kinetic energy is the energy a moving object has. Let us consider a car that accelerates from being stationary (u=0) to travelling at a velocity v when a force, F, is applied.

The time it takes to reach this velocity is give by

The distance moved in this time is given by

Energy transferred = Work Done, Work Done = Force x distance moved and Force = mass x acceleration

Velocity is measured in metres per second, m/s

Mass is measured in kilograms, kg

Kinetic Energy is measured in Joules, J
