Many physics textbook authors, in their books ignore the term "system" when discussing "potential energy of a system" (which is very important)and on reading the text it seems as if the potential energy of a single object is being talked of. This is very confusing.
Does anybody know of any physics book where the topic potential energy is dealt in detail properly and correctly with the specification that potential energy exists only for a system of objects and not a single object and which discusses the same without any discrepancies.
