Question

A large force is acting on a body for a short time. The impulse imparted is equal to the change in

(a) acceleration

(b) momentum

(c) energy

(d) velocity

Answer 1

Correct answer is (b) momentum

If a large force F acts for a short time dt, the impulse imparted is

I = F.dt, = \(\frac{dp}{dt}\).dt

I = dp = change in momentum.
