Web9. Mathematical formulation of second law of motion. Suppose an object of mass, m is moving along a straight line with an initial velocity, v. It is uniformly accel-erated to velocity, v in time, t by application of constant force F throughout the time, t. The initial and final momentum of the object will be, P 1 = mu and P 2 = mv.
