AI overview

Rotation is the spinning motion of an object around a central line called an axis, like how a top spins or how Earth turns on its axis. This type of motion matters because it helps us understand how many objects in nature and everyday life move, from planets and stars to wheels and machinery.

Rotation, rotational or rotary motion is the movement of an object that leaves at least one point unchanged. In 2 dimensions, a plane figure can rotate in either a clockwise or counterclockwise sense around a point called the center of rotation. In 3 dimensions, a solid figure rotates around an imaginary line called an axis of rotation.
