Resumen
In a recent note, Martin Lieberherr1 appears to argue in favor of studying the notion of “centrifugal force” in elementary mechanics courses, effectively countering Wörner’s argument2 against it. I appreciate the discussion this topic has generated, and while I respect Lieberherr’s perspective, I support Wörner’s view. Over a dozen years of teaching introductory physics courses, I have observed that understanding the true essence of the laws of dynamics is one of the most challenging topics for students. It is particularly difficult for them to understand why the first law is not simply a special case of the second law, which introduces the concept of inertial reference frames and effectively distinguishes true forces from fictitious ones
