How does the force needed to change momentum depend on the time rate at which momentum changes.

Question

How does the force needed to change momentum depend on the time rate at which momentum changes.

In: Physics

Answer 1

Momentum is mass x velocity

Change in momentum is thus usually a change in velocity (unless the object is falling apart i guess).

Change in velocity over time is acceleration

Force is mass x acceleration

So (assuming constant mass) the rate you change momentum depends on the rate you change velocity, which is acceleration. acceleration depends on force
