Centrifugal Force

Centrifugal Force:
1. It acts normally on the same particle executing uniform circular motion.
2. It is directed radially away from the centre of the circle.
3. It cannot be associated with any agent.
4. It is a fictitious force in an inertial frame of reference.
5. It is the tendency of the body to fly away from the centre of the circle.
6. It comes in to play in a rotating frame of reference.
7. In a uniform circular motion, its magnitude is constant and equal to that of the centripetal force.
8. Centrifugal force depends on mass 'm'. Hence bodies of higher mass rotate on a circle of higher radius (principle of centrifuge).
