Kinetic Energy

Kinetic energy (KE)

Every moving object has kinetic energy (KE). The more mass an object has and the faster it is moving, the more kinetic energy it has. So the bigger the object, the faster it will move.

This equation shows the relationship between kinetic energy (J), mass (kg) and speed (m/s):

kinetic energy = 1/2 × mass × speed squared
