Question

Quizplus · Accepted Answer

Changes in velocity (v) are usually temporary and can be easily reversed by applying opposite forces. On the other hand, changes in momentum (M) tend to be more permanent since momentum is conserved in a closed system, and any change in momentum will result in an equal and opposite change somewhere else in the system. Therefore, changes in momentum are generally more difficult to reverse compared to changes in velocity.
