What is (mv - mu) / t?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
This formula represents force according to Newton's second law. Here, 'm' is mass, 'v' is final velocity, 'u' is initial velocity, and 't' is time. The expression (mv - mu) represents change in momentum, so dividing by time gives the rate of change of momentum, which equals force (F = ma). This connects kinematics with dynamics, showing how motion relates to the forces causing it.
