Power and work are two important concepts in mechanics. The main difference between them is time. Both these terms are closely related to each other but note that they cannot be used interchangeably. Work is defined as the energy required to move an object from one point to another, whereas, power is the energy transferred per unit time.
Difference between Momentum and Inertia
Let us look at more differences between them in the table given below
|Work is a scalar quantity.||Power is a scalar quantity.|
|The SI unit of work is Joule (J).||The SI unit of power is Watt (W).|
|The equation to calculate work is
Work = Force × Displacement.
|The equation to calculate power is
Power = Work/Time
|Work can also be measured in units like electron volt (eV), kWh, MWh, and GWh.||Energy is also measured in units like kW, MW and GW.|
The difference between work and power should be understood clearly as these are an important topic in Physics.
