What does a Joule unit measure?
The joule 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.
