Show Summary Details


This chapter begins with a brief description of friction and drag. Friction and drag have one property in common — both are nonconservative forces; that is, they cannot be stored as potential energy of one kind or another for later retrieval. Rather, they “go to waste” and produce “useless” heat. The discussions then turn to heat and work, heat and temperature; heat and internal energy; entropy; the impossibility of perpetual motion; and mythical perpetual motion machines.

Keywords: friction; drag; nonconservative forces; heat; work; temperature; internal energy; entropy; perpetual motion
