- 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 v then its linear momentum can be given by p= mv and if
forceF is applied on a body, then
(K = 1 in C.G.S. and S.I. units)
FORCE = MASS × ACCELERATION
