Difference Between Force And Power. In this article, you will come to know about what is force, what is power, what is the main difference between force and power, and a comparison between force vs power.

Both the terms force and power are related to the study of mechanics. The two terms have similar connotations. But, in physics, force and power have different meanings. Here, we will first discuss the main difference between force and power. Then, differentiate them in detail.

What Is The Main Difference Between Force And Power?

The main difference between force and power is that the:

-Force is referred to as the rate of change of momentum. It can change the momentum of any object.

-Power is referred to as the rate at which the force is able to transfer energy.

What Is Force?

Force is referred to as the rate of change of momentum. It can change the momentum of any object. Force is a vector quantity. It is measured in units of newtons (N). A force that is equal to 1 N is equal to the weight of an apple.

Force (N) = mass (kg) × acceleration (m/s²)

In other words, force is also the act of push or pull. A force is needed to change the motion of an object, like pushing a bicycle. There are various examples in which force is very necessary. In an electric circuit, force is very important because it causes the electrons to move around the circuit. It is also very important to keep protons, neutrons, and electrons bound together. Similarly, planets, stars, and galaxies are attracted to each other via the force of gravity.

What Is Power?

Power is referred to as the rate at which the force is able to transfer energy. Any work is done when the force is applied to an object. Power is actually the rate of doing any work. It is a scalar quantity.

The work is done by W, and time is given by t then the power P is given by:

P = E/t

The power is measured in joules per second (Js-1) or watts (W). 1w=1js-1.

There are many examples of forces in which the rate of energy is transformed from one form to another. In a light bulb, the wattage is the force, in which the bulb converts electrical energy into light.

Therefore, it is clear that power is not a measurement of the force exerted on an object, but it is the rate at which the force can do the work.

Comparison Between Force Vs Power:

-Force change the momentum of an object.
-Power is the rate of energy that is transferred from one object to the other.

-Force is a vector quantity.
-Power is a scalar quantity.

-Force is measured in Newtons (N).
-Power is measured in Watts (W).
