Explanation:

What is Motion in One Dimension?

A particle is said to be traveling in one dimension if it only changes direction once during its journey. An ant, for instance, traveling along the X-axis

What is Motion in Two Dimensions?

Two-dimensional motion is the term used to describe motion in a plane.

What is Motion in Three Dimensions?

The three-dimensional motion refers to motion in space that includes all X, Y, and Z axes.

Thus, rotation is a motion that modifies a body's orientation.
