I am confused about the relationship between the centrifugal force and radius.
The centrifugal force equation for an object having constant mass and angular velocity moving around the earth on GRS80 reference is Fc = m w^2/r (m=mass, w^2=angular velocity of the earth, r=earth's radius)
From this equation, the centrifugal force would have an inverse proportion to the earth's radius, but logically as the radius decreases the centrifugal force would decrease until we reach the center which no force would be there.
Can anyone explain this issue and how the graph in this case would be?
