- an outward force on a body rotating about an axis, assumed equal and opposite to the centripetal force and postulated to account for the phenomena seen by an observer in the rotating body.
- a fictitious force that can be thought of as acting outwards on any body that rotates or moves along a curved path
- An effect that seems to cause an object moving in a curve to be pushed away from the curve’s center. Centrifugal force is not a true force but is actually the effect of inertia, in that the moving object’s natural tendency is to move in a straight line. See Note at centripetal force.
A force that tends to move objects away from the center in a system undergoing circular motion. Centrifugal force keeps the water in a whirling bucket from spilling or throws a rider in a car against the door when the car goes around a sharp curve. Centrifugal force is actually a form of inertia.
