Answer: It is described as the motion of a body, not as the motion of a point mass object whose individual elements move equally in independent directions around concentric circles. These circles’ centres are situated on a line known as the rotational axis, which rotates through equal angles in an equal amount of time.
Examples: The blades of a fan, and a spinning wheel.
The phrase “rotary motion” refers to an object’s actual physical movement while it is rotating around its own axis when we say that an object is rotating uniformly or that it is moving in a circle or rotary fashion, we are referring to the fact that its velocity is constant.
