What does centrifugal force increase with?


Quick Answer

Centrifugal force increases proportionally with the distance from the axis of rotation. Centrifugal force also increases with the rate of rotation of the axis, though it is proportional to the square of the rate of rotation rather than directly to the rate of rotation itself.

Full Answer

Centrifugal force is the apparent force that seems to draw an object attached to a rotating axis away. This is actually due to the inertia of the object, which is why the force seems larger when the rate of rotation or distance from the axis increases. Centrifugal force is referred to as an inertial or fictitious force, as it only exists in a rotating frame of reference and does not obey Newton's second law that the rate of change of the speed of an object is equal in both magnitude and direction to the force imposed on it.
