Impulse of Force - HyperPhysics Concepts

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:

What is the equation for impact force? - Quora

Jul 02, 2016· As David Vanderschel said, you will always have to calculate the force by newton’s laws (if you are in the domain of classical physics). And indeed, I know no classical recurrent function for impact forces. Nevertheless, I’ve taken a look on some papers about collision forces, and they generally mention two important parameters: Peak force & Impact pulse width.
