Circular motion is an example of motion in:

Explanation

Uniform In a circular motion, an object moves in two dimensions with a constant speed in a fixed circular direction; however, because the object's direction changes at every point, the velocity also changes, and the direction at each point is always the tangent. Another illustration of motion in two dimensions is uniform circular motion, where the item moves in a circle at a constant speed, but the velocity changes at each location as the velocity vector's direction changes. Hence, a circular motion is two-dimensional as it describes movement in a plane.
