rotational motion
Turning around axis
Rotational motion is movement around an axis or center point, as opposed to linear motion along a path.
A spinning top, a turning wheel, and Earth's daily rotation all exhibit rotational motion.
The term appears in physics discussions of angular velocity, torque, and moment of inertia: The rotational motion of the flywheel stores kinetic energy.
