A joule is the unit of what quantity?

Explanation:
The joule measures energy (and work). It is defined as the amount of energy transferred when a force of one newton moves an object one meter, so 1 J = 1 N·m. This shows why it is the unit of energy. Power is measured in watts (joules per second), force is measured in newtons, and charge is measured in coulombs, so the joule is not a unit for those quantities.
