  • Impulse of Force

    Minimizing Impact Force. The process of minimizing an impact force can be approached from the definition of the impulse of force: . If an impact stops a moving object, then the change in momentum is a fixed quantity, and extending the time of the collision will decrease the time average of the impact force by the same factor. This principle is applied in many common-sense situations:
