### How would you calculate the force of a hammer hitting an ...

2018-11-5 The force between hammer and anvil is, indeed, very difficult to calculate. There are two significantly different cases: 1) where the interaction is elastic (no permanent deformation of either the hammer or the anvil; and 2) where the interaction is inelastic (e.g., the hammer leaves a dent in the anvil).

2017-2-3 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:
