What is the SI unit of energy?

Explanation:
Energy is the amount of work that can be done, and in SI units that amount is a joule. A joule is defined as the work done when a force of one newton acts over a distance of one meter in the direction of the force. In base units, this is kg·m^2/s^2. The other units shown correspond to different physical quantities: a watt measures power, the rate of energy transfer; a newton measures force; and a pascal measures pressure. For example, lifting a 1-newton force by 1 meter requires 1 joule of energy.
