Question by RLin · May 03, 2015 at 12:13 AM · collisionrigidbodyvelocityspeedforce

How to get collision force, not relative velocity?

I know this has been asked before, but I never found a clear answer. The problem with relative velocity is that the object can scrape another at high speed; the relative velocity will be high, but the force will be low.

Sounds like you want to look at the dot product between the relative velocities and the collision normal. If I worked that out right it should give you some useful values.

Thanks for the advice! I tried what you suggested and it works great now! I'd never thought of that before.
