Impulse Momentum Theorem

Impulse momentum theorem Impulse momentum theorem states that change of momentum of a body is equal to the impulse applied to it. Here Momentum is the product of mass and velocity of the body and we call it as the ‘Inertia to motion’ as well. And Impulse is produced when a considerable amount of force
