How much force?

This may be a simple question to you math wizs out there…

In Unity, if I have two objects moving twards each other, and they collide. I want to be able to measure how much force it was.

How would I go about figuring that out? I would like to measure the force of the impact, and then based on that force, if it is > then (some value) i want the colliding object to “break”.

Anyone know how to achive this?

Newton: F=ma, p = mv

If you know the mass of your object, and it’s acceleration, you know the force it carries. There is a nice discussion of this subject here: Force, Momentum, and Impulse

But for your purposes, multiply the velocity times the mass (to get momentum) and compare that to some threshold value. Unless it needs to be really accurate, that should be close enough an approximation.
