Centrifugal force

Centrifugal force Centrifugal force is a ficttious force in Newtonian classical mechanics. In every rotating frame of reference. In rotating device like centrifugal pump, centrifuge, centrifugal clutches, centrifugal force is applied. Earth is a rotating frame of reference but it's fictitious force is small due to slow rotation. In any point of earth surface the strength and local gravity is the combination of centrifugal force and gravitational force. An object weighted on a spring have two force. In downward direction we find gravitational force and in upward direction we find restoring force of spring. Rotating force motion results another fictitious force that is called Coriolis force. Rate of rotation in a frame of reference if changes another fictitious force is required that is called Eular force.
