## Physical Law

**Newton's second law of motion** is one of three physical laws that forms the basis for classical mechanics.

### Statement of Law

- The total force applied on a body is equal to the derivative with respect to time of the linear momentum of the body:

- $\mathbf F = \map {\dfrac \d {\d t} } {m \bsv}$

As Isaac Newton himself put it:

*The acceleration produced by a particular force acting on a body is directly proportional to the magnitude of the force and inversely proportional to the mass of the body.*

## Also known as

This law is also often referred to as just **Newton's second law**.

## Also see

- At velocities near the speed of light, see Einstein's Law of Motion.

## Source of Name

This entry was named for Isaac Newton.
