what are the units for power and work
In physics, power is the rate of doing work. It is equivalent to an amount of energy consumed per unit time. In the SI system, the unit of power is the joule per second (J/s), known as the watt in honour of James Watt, the eighteenth-century developer of the steam engine. The integral of power over time defines the work performed.
1 F is force, d is the distance over which the force is applied, and Î¸ is the angle between the force and distance. 2  Derived units, sign conventions. 3  Work is energy, and the unit is the Joule. 4  Joule = NÂ·m = kgÂ·m/s 2 Â·m = kgÂ·m 2 /s 2. 5  If the force and the distance applied is in the same direction, work is positive.
