A little fuel for the fire.
From the Rotorcraft Flying Hand Book.
CENTRIFUGAL FORCE - The apparent force that an object moving along a circular path exerts on the body constraining the object and that acts outwardly away from the center of rotation.
CENTRIPETAL FORCE - The force that attracts a body toward its axis of rotation. It is opposite centrifugal force.
From the dictionary of aeronautical terms.
Centrifugal Force. A force that acts outwardly on any body moving in a curved path. Centrifugal force tries to move a body away from the center of its rotation, and this force is opposed by centripetal force.
Centripetal Force. The force within a body that opposes centrifugal force as the body rotates or spins. Centripetal force acts inside a piece of rotating machinery and tries to pull the rotating object in toward the center of its rotation.
