energetics

Energetics took its rise as an outcome of the discovery of the principle of the conservation of energy.

A book full of the energetics of a master workman is just what every young man cares for.

It is a case in which the simple doctrine of energetics becomes inadequate before the limit is reached.

It was by the study of heat, and more especially of thermodynamics, that we obtained our conceptions of the science of energetics.

We must therefore add a third to the two laws of energetics, Mayer's law of conservation, and Carnot's law of fall of potential.
