Important Note: Centrifugal force does not actually exist.

Important Note: Centrifugal force does not actually exist. We are in a non-inertial coordinate system. Nevertheless, it appears quite real to the object being rotated. Centrifugal force is like Newton's "Every action has an equal an opposite reaction.” When you step on the gas in your car you hit the seat behind you as if you are going backwards but you are really going forwards. As soon as you stop pulling on the merry go round (applying an inward, not outward force) you will fly off in a straight line. No more force inward, no more going in a circle.
