It has a quality or kind that is determined by its proportion of force to motion.

     Specific events differ one from another in two ways; either as to the quantity of energy involved — the mass-motion product, and as to their quality or kind. The quality of an event depends not upon the product of its mass or force and motion but on the ratio between them, the amount of force per each unit of motion. The quantity becomes actual as action by reason of its period or frequency in time. Hence the quantity of the event as action is its Energy, its potential energy, multiplied by its period or time. If it becomes a continuing or cumulative event, such as a succession of waves or of generations, then the total energy, as action, is the product of
