# Newton's Laws of Motion/Second Law

## 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.
