Difference between Work and Power

Work is defined as the process of transferring energy to move matter through the application of force. This is often presented as the product of force and displacement. The SI unit of work is the Joule.

Difference between Work and Power

Power is defined as the energy transferred per unit time. The SI unit of power is the watt. One watt equals one joule per second. A lot of power is digital.

What is Work?

The energy consumed or the energy used to move an object from one place to another is called work and we do many of these things in our daily lives that define work.

The SI unit of work is the joule, where we represent j. According to the mathematical expression, the work done is defined as the product of the components of the force in the direction of movement and the magnitude of the movement or we can say the energy transferred

What is Power?

The SI unit of power is the watt (W). In mechanical devices or automobiles, the SI unit is unique and measures horsepower (hp). Watts can also be regarded as a unit of electricity in everyday life.

This means that electricity is a form of energy. The main advantage of force perception is that physical force determines the speed at which a task can be performed and has a relationship with the task.


But energy is more used in daily life compared to work. Power refers to the rate at which work can be done and can be slow or fast. Every time work is done, the man or machine uses its own energy to complete the work.

Difference between Work and Power



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.
