Impulse Momentum Theorem

Impulse momentum theorem states that the change of momentum of a body is equal to the impulse applied to it. Mathematically, its represented with this equation: Δp = F . Δt Here, Δp = change in momentum. And F . Δt is the impulse applied. Impulse is represented as the product of Applied force F […]
