Is circular motion two-dimensional?
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. In this case, the item moves in a circle at a constant speed, but the velocity changes at each location as the velocity vector's direction changes. The two-dimensional motion describes movement in a plane. Two dimensions are used to describe circular motion.
Hence, a circular motion is two-dimensional.
