Magnetic, kinetic, heat, light, gravitational potential, chemical, sound, elastic potential, electric and nuclear.
1 of 7
State the law of conservation of energy
Energy cannot be created or destroyed but it can change from one to another
2 of 7
Identify useful and wasted energy in a given system
Eg. a bulb gives off light and heat light is useful and heat is wasted.
3 of 7
Calculate the efficiency of an energy transfer
(Useful energy supplied energy) 100 . this will give us the percentage of the efficiency.
4 of 7
List different methods of generating electricity and identify them as renewable or non-renewable
Fossil fuels - non-renewable Solar power - renewable Tidal power - renewable Wind power - renewable
5 of 7
Describe and explain how electricity is generated in a power station
Fossil fuels are burnt to make heat energy then the heat is used to create steam which turns a turbine creating kinetic energy and this will drive a generator producing electrical energy.
6 of 7
Explain the benefits of renewable methods over non-renewable methods
A renewable energy will not run out but a non-renewable energy will eventually run out.
