Choose the one which describes uniform circular motion.

Circular motion is the movement of an object around the circumference of a circle or the rotation of an object around a circular path. A force acts at right angles to the particle's velocity indefinitely.

Uniform circular motion refers to circular motion in which the particle's speed remains constant. Force provides centripetal acceleration in a uniform circular motion.

The movement of a watch's second hand is an example of uniform circular motion, as demonstrated above. 

A giant wheel's motion is rotatory because all of the objects within the wheel move in a circular fashion in the same direction around a fixed axis.
