Balls collide with impulse-based physics. At restitution 1, kinetic energy is conserved; below 1, collisions are inelastic and energy drains away.

Governing equation

j = \frac{- ( 1 + e ) ( v _{b} - v _{a} ) \cdot n ^}{1/ m _{a} + 1/ m _{b}}, e = 1.00

Reading this result: With restitution 1 every bounce is perfectly elastic, so the total kinetic energy of all 12 balls stays constant forever — a 2D model of an ideal gas.
