Final answer:
A large force is not always required to change large momentum; a small force can result in the same change if it is applied over a longer period of time.
Step-by-step explanation:
The question involves understanding the relationship between force, momentum, and the time over which the force acts. According to Newton's second law, the change in momentum of an object (commonly referred to as impulse) is equal to the net force acting on the object multiplied by the time interval over which the force acts. A large force is not always required to change large momentum. If a small force is applied over a longer period of time, it can result in the same change in momentum as a larger force applied over a shorter period. This can be seen in the real-world examples where even a small force like gravity can reverse the momentum of a ball thrown upwards, as it acts over an extended period of time.
