A small force could cause the same change in momentum, but it would have to act for a much longer time. In Example 1 in Linear Momentum and Force, a very large force acting for a short time had a great effect on the momentum of the tennis ball. The effect of a force on an object depends on how long it acts, as well as how great the force is.
