View source for A Short Note on Centrifugal Force

Just because centrifugal force isn't a Newtonian force doesn't mean that it isn't a real force. While the prevailing point of view is, that a Newtonian force is a superior kind of force as compared with an inertial force, this perspective hinges entirely on the existence of the totally undefined concept known as an inertial frame of reference. So first of all, we need to establish the physical basis for an inertial frame of reference, and only then will we be better placed to decide whether or not the Newtonian forces are any more real than the inertial forces.
