AQA GCSE Physics Unit 1 Topic 2 - Using Energy
Forms of Energy
Energy exists in different forms such as: light, sound, kinetic, nuclear, electrical, gravitational potential, elastical potential and chemical.
The last three are forms of stored energy.
Energy can be transferred from one form to another.
Any object above the ground has gravitational potential energy.
A falling object transfers gravitational potential energy to kinetic energy.
Conservation of Energy
It is not possible to create or destroy energy. It is only possible to transfer it from one form to another, or from one place to another.
