<P> The joule ( / dʒ uː l / ) ; ( symbol : J ) , is a derived unit of energy in the International System of Units . It is equal to the energy transferred to ( or work done on ) an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre ( 1 newton metre or N ⋅ m ) . It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second . It is named after the English physicist James Prescott Joule ( 1818 -- 1889 ) . </P>
