Energy can be described as being in different 'stores'. It cannot be created or destroyed but it can be transferred, dissipated or stored in different ways.

This interactive quiz is aimed at GCSE physics students studying types of energy store, energy transfers, energy dissipation, the conservation of energy and energy calculations.

Power is the rate at which energy is transferred. The amount of energy usefully transferred in a system determines how efficient that system is.

Understanding how to approach exam questions helps boost exam performance. Questions will include multiple choice, descriptions and explanations, using mathematical skills and extended writing.
