Energy is Made Up:
Virtual Talk given at the Fall Meeting of the Indiana Section of AAPT in Sept, 2020.
Following the derivation of kinetic and potential energy formulas in the Giancolli textbook, I have been stressing to my students in recent years that energy is a made-up concept, and that–in principle–it is not necessary for building a coherent model of interactions between objects. I discuss how energy is nothing more than a helpful “bookkeeping method” for multi-object systems. This leads to interesting discussions, especially for students who have already taken chemistry.
