A new result of the molecular dynamics computer simulation is presented for a collision process between a domain wall and a phonon in the φ^4 system. We find the momentum exchange between them in the fourth order processes with respect to the incoming phonon amplitude. The domain wall, which was at rest, begins to move with a constant velocity. Using the result of the third order calculations and conservation laws, the velocity is theoretically evaluated. It can reproduce the result of the simulation work.
