Which of the following does not demonstrate uniform circular motion?

Uniform Circular Motion is the motion of a body travelling at a constant speed along a circular path. The speed remains constant, but the velocity varies. When a body moves at a consistent velocity, it is said to be in a uniform motion. Non-uniform movements are accelerated motions.

A jogger in the park can accelerate or decelerate, changing his velocity as a result of his actions. As a result, a running man's motion is not an example of a uniform circular motion.
