How to get the intensity of the force of a collision in a physic simulation?

I need this so that I can destruct an object after a certain level of impact.

Which type of physics simulation? In “regular” Blender or in the BGE?

Physics simulation in BGE.

If you use the print(dir(own)) function, there is a .getReactionForce might not be what you’re looking for, but it’s worth a shot.

This does not provide you with any results.

Currently there is no way to get the force out of bullet. What you can do is to calculate the force out of the acceleration of an object. Keep in mind this does not include any other force (e.g. if the object lays on the ground and another one is on top of it.)

Look at this thread. Maybe it helps:
