What Is Momentum And Motion?

Physical movement or change in position of a body is called motion in the body. The motion of a body is defined by speed, velocity and acceleration. Momentum is described as the quantity of motion in a body. Momentum is equal to the product of mass of the body and velocity of the body.

momentum= mass* velocity

P=mv

According to the law of conservation of momentum, the momentum of a system is always remains constant unless an external force is applied on the system. The rate of the change of momentum is equal to the applied force.

F= ma

F= m dv/dt

F= d(mv)/dt

F= dP/dt
