Concepts from rectilinear kinematics and angular kinematics were combined in the topic of plane motion. In plane motion, the center of gravity of a body moves along a path (rectilinear motion) while the body rotates about its center of gravity (angular motion). The topic of relative motion was introduced to describe the linear velocity of any point on the (rotating) body, with respect to the center of the body.

Provide an in-context example or application that describes the idea of relative velocity, in the context of this Dynamics course. Provide illustration or video link with your answer of approx. 250 words or less, with APA references.
