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: http://spiff.rit.edu/classes/phys311.old/lectures/impulse/impulse.html
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.Tue, 20 Mar 2012 01:31:41 GMTDaveA
