Lesson outcome
I can calculate the energy an object has because it is moving.
Show transcript
Energy is measured in joules (J).
Doubling the mass of a moving object doubles the energy it has in its kinetic store.
Doubling the speed of an object increases the energy it has in its kinetic store by four times.
The energy an object has in its kinetic store of energy is found using the equation Ek = ½ mv².
