Collision phenonena of the separated rocket stages due to the residual thrust of the empty stage are studied. Two cases, one where the collision occurs within a time as short as a few minutes, the other where it occurs after a time as long as orbital period, are discussed. In the latter case, the relative motion of the stages is analyzed under the assumption that the reference orbit is circular and the magnitude of the residual thrust is constant. Especially, as to the case of spin separation where the direction of the residual thrust is kept constant with respect to the inertial frame, the position where the collision occurs and the angle between the initial relative velocity vector and the direction of there sidual thrust which is required so that the collision occurs are obtained as a function of the residual acceleration level.
