We all know that the Centrifugal force is not a real force.However,we can use it mathematically.
This Wikipedia Article on Centrifugal force
States that:
According to Newton's first law,objects tend to move in a straight line or stay at rest at a constant velocity unless no external force is acted.
The Centrifugal force should act on the velocity direction.If so,Why does the wikipedia article says this.
Moreover,There have been many ideas of artificial Gravity using centrifugal force.(So,in favor of wikipedia article)
Whatever the Wikipedia,My question is why does not the force act at velocity direction?
This Wikipedia Article on Centrifugal force
States that:
But,The concept of centrifugal force is applied in rotating devices such as centrifuges, centrifugal pumps, centrifugal governors, centrifugal clutches, etc., as well as in centrifugal railways, planetary orbits, banked curves, etc. These devices and situations can be analyzed either in terms of the fictitious force in the rotating coordinate system of the motion relative to a center, or in terms of the centripetal and reactive centrifugal forces seen from a non-rotating frame of reference; these different forces are equal in magnitude, but centrifugal and reactive centrifugal forces are opposite in direction to the centripetal force.
