Which unit is used to measure energy and work?

Explanation:
Energy and work are measured in joules. This unit comes from the idea that work equals force times distance (W = F × d). Since force is in newtons and distance in meters, their product is newton-meters, which is defined as a joule. Energy is the capacity to do work, and when energy is transferred by doing work, the amount transferred is measured in joules. For contrast, a watt is a unit of power (the rate of energy transfer, 1 joule per second), a newton is a unit of force, and a pascal is a unit of pressure (force per area).
