Centrifugal force is defined as what kind of force?

Centrifugal force is conceptualized as an outward force that is perceived in a rotating reference frame. It arises when an object is in circular motion and feels as though it is being pushed away from the center of rotation. This phenomenon is due to the inertia of the object, which tends to keep it moving in a straight line. As the object rotates, this tendency to move straight creates the sensation of a force acting outward from the center.

In practical terms, when a car makes a turn, passengers feel pushed against the outer side of the vehicle due to this perceived centrifugal force. While the object is actually being pulled toward the center by centripetal force (which is the true force acting on it), the effect of inertia creates the experience of centrifugal force. Thus, identifying it as an outward force caused by rotation properly captures its essence in the context of rotational dynamics.
