### Work Power Energy Cheat Sheet Introduction

1 joule=1N.1m Power Power is the rate of work done in a unit of time. The unit of the power from the equation given above, joule/s, however, we generally use the unit of power as watt. 1joule/s=1watt ENERGY The capability of doing work is called energy. If something has energy then it can do work. It has the same unit with work joule.
