Definition of Force. Force is something that enables us to do any work. It is the push or a pull acting on a body, which cannot be seen but can only be felt. It is a vector quantity because it can be described by both magnitude and direction and the SI unit of Force is Newton represented by the symbol F.

In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate.
Other units:dyne, pound-force, poundal, kip, kilopond
In SI base units:kg·m/s2
SI unit:newton (N)

- So what is force? When we push or pull anybody we are said to exert force on the body
- Push or pull applied on a body does not exactly define the force in general. We can define force as an influence causing a body at rest or moving with constant velocity to undergo acceleration
- There are many ways in which one body can exert force on another body. Few examples are given below
- (a) Stretched springs exerts force on the bodies attached to its ends
- (b) Compressed air in a container exerts force on the walls of the container
- (c) Force can be used to deform a flexible object
- Force of gravitational attraction exerted by earth is a kind of force that acts on every physical body on the earth and is called the weight of the body
