Question

How does impulse-momentum theorem relate to Newton's second law?

Answer 1

Newton second law states that the force acting on the body is directly proportional to the mass of the object. The sign of proportionality is replaced by the acceleration of the object.

Now impulse momentum theorem states that the net impulse acting on the object is equal to the change in the momentum of the object. It is worth noting that the impulse is nothing but force acting for a short period of time.

As acceleration is rate of change of velocity so when we multiply both sides of Newton second law by time then on one
