Edexcel Physics IGCSE - Energy Resources and Energy Transfers

Front

Chemical Energy

Back

A store of energy found in things such as batteries, fuels and food.

Front

Closed System

Back

A system that experiences no net change in its total energy when energy transfers occur within it.

Front

Conduction

Back

The transfer of heat energy through the vibrations of particles in a medium.

Front

Conservation of Energy

Back

The law that energy can be transferred, stored or dissipated but never created or destroyed.

Front

Constant Temperature

Back

Bodies at a fixed temperature radiate the same average power that they absorb.

Front

Convection

Back

The transfer of heat energy through convection currents in a fluid.

Front

Elastic Potential Energy

Back

The store of energy that stretched or compressed objects contain.

Front

Electrostatic Potential Energy

Back

The store of energy due to the relative position of a charge in an electric field.

Front

Fossil Fuels

Back

Coal, oil and gas.

Front

Gravitational Potential Energy

Back

The store of energy that all raised matter has, directly proportional to mass, distance raised, and gravitational field strength.
