Another possible explanation, is that potential energy is not lost if no "action" is done, while kinetic energy is lost if the "action" is not continued.. In the case of the spring and the capacitor, potential energy is stored, while for a mass and an inductor, it is the motion that generates the kinetic energy. Since there are a number of things that
