# Newtonâ€™s Second Law

The rate of change of linear momentum of a body is directly proportional to the external force applied on the body and this change takes place always in the direction of the applied force.

If a body of mass m, moves with velocity , then its linear momentum can be given by  and if force  is applied on a body, then

or  (K = 1 in CGS and SI units)

(as  acceleration produced in the body)

Force = mass Ã— acceleration
