We know that the Earth is rotating, and its gravitational force is the centripetal force. So if I'm standing on the Earth, I'll feel 3 forces: Gravitational force, normal force and centrifugal force. However, the magnitude of the centrifugal force is equal to the gravitational force, so wouldn't the 2 forces cancel out, leaving the normal force to be 0? Why is the normal force I feel= the magnitude of the gravitational force, when I can feel the centrifuhal force?
