Question

Prove that impulse(force)=change in momentum

Answer 1

according to newtons second law of motion
F=m×a
F=m×(v-u/t)
F×t =m×(v-u)
F×t=mv-mu
therefore impulse =change in momentum.

Answer 2

We know that, J = F × ∆t

J = ma × ∆t

J = m (∆v/∆t) × ∆t

J = m (∆v)

J = m (v - u)

J = mv - mu

J = pi - pf

J = ∆p

hope this helps u❤️
