Question

what is relation between force and rate of change of momentum

Answer 1

Knowing the amount of force and the length of time that force is applied to an object will tell you the resulting change in its momentum. They are related by the fact that force is the rate at which momentum changes with respect to time (F = dp/dt). Note that if p = mv and m is constant, then F = dp/dt = m*dv/dt = ma.

Answer 2

According to newton's second law, the change of the momentum of an object is equal to the net force acting on it.

F = ma
