What is the conservation of energy principle?
Energy can be transferred usefully, stored or dissipated, but can never be created or destroyed
1 of 6
When energy is transferred what happens?
Not all energy is transferred usefully into the store that we want it to go to. Some energy is dissipated
2 of 6
What is energy dissipation?
A process in which energy is wasted because the energy is being stored in a way that isn't useful.

Give an example of energy dissipation
A phone. When using a phone energy is usefully transferred from the chemical energy store of the battery in the phone however some energy is dissipated to the thermal energy store of the phone
4 of 6
To calculate the rate of energy transfer what equation would you use?
Energy Transferred= Power x Time
5 of 6
The efficency for any energy transfer can be worked out by using what equation
efficiency= Useful output energy transfer / Total input energy transfer
