Final answer:
Rotation about an arbitrary point refers to the circular motion of an object around a non-fixed axis or point. Each point in the object follows a circular path around that point.
Step-by-step explanation:
The circular motion of an object around a non-fixed axis or point is referred to as rotation about an arbitrary point. Every point within an object rotates around a single, randomly chosen point by following a circular path. One example of this kind of rotation is the rotation of a CD around its center. In this instance, a circular arc centered at the rotation point is followed by every point on the CD.
