     In treating of energy-in-action as a concrete quantity of work or action, physical science presupposes, (1) a mass, body or particle moving at a given rate and for a given period of time. (2) The mass units are of a given number per each motion unit. The motion units are of a given number per each time unit. (3) A given number of time units.

     A dyne is the force — push or pull — requisite during one second to change the relative velocity of each or any one gram in any mass by 1 centimeter per second, or, conversely, the force exerted by each or any gram in that mass during such change.

     The kinetic energy contained in any body in virtue of its relative velocity is the number of

     When any mass has uniform motion, relative to its environment, in centimeters per second, any change in that number of centimeters
