Kinetic energy
Leaving Cert Physics · Forces and Motion
Higher Level
The store of energy a body has because it is moving, calculated as half the mass multiplied by the square of the speed. Because the speed is squared, doubling the speed of a car quadruples the energy that its brakes have to remove.
Ordinary Level
The store of energy an object has because it is moving. The faster and the heavier it is, the more of it there is.
