Q:

# What does centrifugal force increase with?

A:

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.

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.

Because velocity is the rate of motion of an object in a specific direction, either an increase or decrease in the object's speed or a change in its direction of travel causes its velocity to change. This change in velocity is defined as an acceleration, which according to Newton's laws of motion occurs because of an unbalanced force acting on the object.

Centripetal force refers to the force that makes objects move in circular paths. Centripetal force makes an object or body follow a curved path; the direction of the body moves towards the center or fixed point of the circular path.

The equation for determining the net force acting on an object is F = ma, or force equals mass times acceleration. Net force is measured in terms of acceleration, which means a change in velocity. If there is no change in velocity, the net force is considered to be zero.
