Energy transfers
Different forms of energy can be transferred from one form to another.
Energy transfer diagrams show each form of energy - whether it is stored or not - and the processes taking place as energy is transferred.
The energy transfer diagram below shows the useful energy transfer in a car engine.
You can see that a car engine transfers chemical energy, which is stored in the fuel, into The energy an object possesses due to its motion. in the engine and wheels.
This diagram shows the The different ways in which energy can be transferred from one store to another includes heating, by waves, electric current or by a force moving an object. for the useful energy transfer in an electric lamp.
You can see that the electric lamp transfers or converts electrical energy into light energy.
Note that these energy transfer diagrams only show the useful energy transfers.
However, car engines are also noisy and hot, and electric lamps also give out heat energy.
