Energy cannot be created or destroyed but it can be transferred, dissipated or stored in different ways.

There are two types of energy resource: renewable and non-renewable.

When work is done on an object, energy is transferred. Power is the amount of work done in one second. Efficiency is a measure of how much useful energy is converted.

In this CCEA GCSE physics quiz, you can test your knowledge of kinetic and gravitational potential energy. You can also answer physics GCSE test questions about kinetic energy.
