Newton’s Second Law and equation of Force

Newton’s Second Law states that the rate of change of momentum of a body is directly proportional to the net force applied on it, and this change in momentum takes place in the direction of the applied force. Mathematically it can be stated this way: F∝ (mV-mU)/t. Here, F is the net force acting on the […]
