Work is defined as the process of energy transfer for the motion of an object through the application of force. This is usually represented as the product of force and displacement. The SI unit of work is Joule.
Power is defined as the amount of energy transferred in unit time. The SI unit of power is the watt. One watt is equal to one joule per second. Power is a scalar quantity.
Difference between Work and Power
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.||Power is also measured in units like kW, MW and GW.|
The difference between work and power should be understood clearly, as this is an important topic in Physics.
