      - can be transferred in four ways
        
        mechanically
        
        due to a force acting on it
        
        pushing, pulling,stretching or squashing
        
        electrically
        
        current through a potential difference
        
        charges moving in a circuit
        
        heating
        
        heat transferred from hot to cold
        
        heating a pan of water on a hob
        
        radiation
        
        energy transferred by light/sound waves
        
        sun giving off heat
    - - is equal to energy tranferred
