Concept:Translational motion is the movement of a body from one point to another without any rotation.Explanation:A body in linear motion moving from point P to point Q travels along a straight path.In translational motion, every part of the body moves through the same distance in the same direction.Since the body simply changes position from P to Q, it experiences no rotation or circular movement.It is not oscillating about a fixed point, so it is not simple harmonic motion.Therefore, the motion is purely translational.Answer:A. Translational
