# Full energy transfer between two identical objects

I'm trying to simulate a game like billiards / shuffleboard / curling where two objects collide and under a perfect direct hit all energy is transferred to the second object. Both matter.js and p2.js create a world where the expected gravity is in Y axis. Setting gravity to 0 and air friction to something high I can get a pretty good simulation of birds-eye view. However when two identical objects collide at low speed they both continue moving forward.

I kept playing with mass, restitution, slop, etc. Cannot simulate a situation where one object stops and the other starts moving (low speed). Any advice would be greatly appreciated!
