A rotational motion is the movement of the body around a fixed straight line.
EXPLANATION:
The body moves along circles on a same plane. The centers of these circle is a fixed line perpendicular to the parallel plane. The line is known as axis of rotation. The force by which the turning effect occurs is known as 'torque'. Torque is the product of force and the perpendicular distance from its axis. SI unit of torque is Newton meter.
