1051 - What is the difference between potential energy and kinetic energy?
Imagine you're rolling a ball down a hill.
- 'Potential energy' is the energy the ball has at the top of the hill, before it starts rolling. It's like stored energy, waiting to be used. 
- 'Kinetic energy' is the energy the ball has as it rolls down the hill. It's the energy of movement, showing that the ball is actually doing something – moving.
