The four energy pathways are: radiation, heating, mechanically, and electrically.


The unit of work is Joules (J\text{J}).


The eight energy stores are: kinetic, gravitational potential, elastic potential, chemical, thermal/internal, magnetic, electrostatic, and nuclear.


The main store changes as a ball is thrown upwards is that Kinetic store decreases and the Gravitational potential store increases.


The store changes when a moving car brakes is that the car’s kinetic store decreases and the thermal stores of brakes and tyres increases because of the friction.


When a kettle heats water, the starting store, energy pathway and final store is: energy is transferred electrically from the socket, increasing the thermal store of the water and the main area of the kettle.
