<P> The second law states that the rate of change of momentum of a body is directly proportional to the force applied, and this change in momentum takes place in the direction of the applied force . </P> <Dl> <Dd> F = d p d t = d (m v) d t . (\ displaystyle \ mathbf (F) = (\ frac (\ mathrm (d) \ mathbf (p)) (\ mathrm (d) t)) = (\ frac (\ mathrm (d) (m \ mathbf (v))) (\ mathrm (d) t)).) </Dd> </Dl> <Dd> F = d p d t = d (m v) d t .

Since Newton's second law is valid only for constant - mass systems, m can be taken outside the differentiation operator by the constant factor rule in differentiation . Thus, </P>
