What is the relationship between impact force and time as momentum decrease to zero?

As momentum decreases to zero, the impact force typically decreases as well, but the time over which the force is applied increases. This relationship is described by the impulse-momentum theorem, which states that the change in momentum is equal to the force applied multiplied by the time over which it is applied. In general, a longer time duration for the force to act results in a smaller force required to bring the object to rest.
