Strongly Associated with:   centrifugal force
Notes:
An object can travel in a circle only if there is a centripetal force on it.

Centrifugal force is sometimes called a fictitious force because when most people talk about centrifugal force pulling outward, they are really talking about the centripetal force that keeps the object from flying outward. The object is just trying to follow a straight line at every instant (and would) were it not for the centripetal force holding it in place.
