View the full answer Step 2/2 Final answer Previous question Next question WebMomentum (P) is equal to mass (M) times velocity (v). But there are other ways to think about momentum! Force (F) is equal to the change in momentum (ΔP) over the change in time (Δt). And the change in momentum (ΔP) is also equal to the impulse (J). Impulse has the same units as momentum (kg*m/s or N*s). Created by Sal Khan. Sort by: Top Voted

WebYour momentum would continually rock back and forth to the point that you would gain 0 displacement and a change in momentum equal to 0. Since the impulse momentum theorem is Fnet*change in time=change in momentum, having a change in momentum of 0 would cause a net force of 0. WebAnswer (1 of 3): What causes a change in momentum?
