Key Stage 3
Meaning
An Energy Transfer is when energy moves from one energy store to another energy store.
About Energy Transfers
- Energy can be transferred from one object to another or between energy stores within the same object. For example on a pool table when white ball hits another ball energy is transferred from the kinetic store of the white ball to the kinetic store of the other ball.
There are 4 ways energy can be transferred;
- Mechanically - By the action of a force.
- Electrically - By an electrical current.
- By radiation - By Light waves or Sound waves.
- By heating - By conduction, convection or radiation.
Key Stage 4
Meaning
An Energy Transfer is when energy moves from one energy store to another energy store.
About Energy Transfers
- Energy and be transferred between stores in a system. This may be between the different energy stores of a single object or between the energy stores of different objects within that system.
- When there is an energy transfer energy is neither created, nor destroyed. This means when that when one energy store decreases, one or more others must increase.
- Humans use energy transfers for a number of reasons but they usually result in some energy being transferred to an unwanted store. This is known as Wasted Energy.
There are 4 ways energy can be transferred;
- Mechanically - By the action of a force.
- Electrically - By an electrical current.
- By radiation - By Light waves or Sound waves.
- By heating - By conduction, convection or radiation.
