The joule is the SI unit of which quantity?

Explanation:
The joule is the unit of energy in the SI system. It’s defined as the amount of energy transferred or work done when a force of one newton moves an object one meter in the direction of the force. That makes it the unit for energy (and for work). Power is a rate of energy transfer and uses watts (joules per second). Charge is measured in coulombs, and force is measured in newtons. So the joule specifically measures energy. For example, lifting a one-newton force through one meter requires one joule of work.
