Analysis of a classical random binary collision model shows that for an N-body system in which elastic, binary collisions are occurring randomly, more than 50% of such collisions involve the transfer of kinetic energy from particles with higher to particles with lower initial absolute momentum, the net result being the overall transfer of kinetic energy in this same direction. The result points to a dynamical interpretation of the thermodynamic arrow of time.
