At the spring meeting of the American Potential Energy Society, a debate erupts over the choice of a reference point for elastic potential energy. One faction (group #1) feels it is only natural to choose the reference point at the location at which the spring is neither stretched nor compressed and to measure the elastic potential energy relative to that unstrained configuration. Another faction (group #2), whose members always like to think "outside of the box", wants to choose the...
