A force is an influence which causes a body to undergo a change in velocity.

Force is a vector quantity.


The usual symbol used to denote the force on a body is $f$.


The dimension of measurement of force is $\mathsf {M L T}^{-2}$.

This arises from Newton's Second Law of Motion and its definition as a mass (of dimension $\mathsf M$) multiplied by an acceleration (of dimension $\mathsf {L T}^{-2}$).


The SI unit of measurement of force is the newton.

The CGS unit of measurement of force is the dyne.

Also known as

Some writers and thinkers subdivide the idea of a force into a push or a pull, but such a dichotomy can serve to confuse the fact that they are in fact both forces.

Linguistic Note

The word force is derived from the Latin word fors meaning strength.
