Key Words
Energy stores - where energy is stored. 8 energy stores are:
- Thermal
- Kinetic
- Gravitational potential
- Elastic potential
- Chemical
- Magnetic
- Electrostatic
- Nuclear
Energy transfer - energy is moved from one store to another.
Work done - same as energy transfer.
Closed systems - somewhere where energy does not enter or leave.
Conservation of Energy Principle - Energy can be transferred usefully, stored or dissipated but can never be created or destoyed.
Dissipated energy - when energy is transfered not all of the energy moves usefully to a store, instead it becomes wasted.
Joule (J) - What energy is measured in. 1000 J = 1 kJ (kilo-joule).
