What is the name of the force that causes a rotating body to be drawn away from its center?

Centrifugal force is the term that describes the apparent force that acts outward on a rotating body, drawing it away from the center of rotation. This force is often experienced in a rotating frame of reference. For example, when you are in a car turning a corner, you may feel as if you are being pushed against the door of the vehicle. This sensation is a result of centrifugal force acting on your body as it moves in a circular path.

While centrifugal force is not a "real" force in the sense that it arises from an interaction such as gravity or friction, it is very much a useful concept in understanding dynamics in rotating systems. In physics, it is considered a fictitious force that appears when observing motion from a rotating reference frame.

Gravitational force, on the other hand, is the attractive force that pulls objects towards each other based on their masses. Centripetal force, while related, is the actual force that acts towards the center of rotation, keeping the object in its circular path. Frictional force relates to the resistance experienced by objects in contact, preventing slipping. Thus, centrifugal force is distinct in that it describes the effect experienced as an object rotates, emphasizing the outward drawing action on the rotating body.
