Question by user-12539 (google) · May 09, 2011 at 04:23 AM · gravityforceaccelerationfrictionquack

Net Force between two objects...

I want to find out how hard two objects are pushing against each other from accelerating forces, even when they're stationary. Is there any way to do that?

I too want that kind of feedback form the physics engines, especially in joints, how much force or torque is currently applied, etc etc. They have a breaking system, so surely the data is somewhere accessible but maybe not exposed to the api. hopefully there is way.

You can create your own force field calculation F=k/r^2=ma where r is the distance between object A and object B, and k is proportional to the mass of object A and object B. You can then solve for acceleration using a = k/r^2 and k=G * m(a) * m(b)
