Question

Assertion: The motion of the centre of mass describes the translational part of the motion
Reason: Translational motion means always straight line motion.​

★Translational motion★

Translational motion is the motion by which a body shifts from one point in space to another. One example of translational motion is the the motion of a bullet fired from a gun. An object has a rectilinear motion when it moves along a straight line.
