In science, the suffix -dynamic refers to a "force producing motion" (1827). [1] The term dynamic was used as a term in philosophy in 1817. Its etymology stems from the French dynamique (1762), from German dynamisch, introduced by Gottfried Leibniz 1691 from Greek dynamikos meaning "powerful," from dynamis "power," from dynasthai "be able to have power," of unknown origin. The figurative sense of "active, potent, energetic" is from 1856. Dynamics as a branch of physics was in use from 1788.

The term was first used in a thermodynamical-sense in 1849 by Scottish physicist William Thomson who referred to a "perfect thermo-dynamic engine", in reference to the ideal Carnot engine, having no irreversibility, described by French physicist Sadi Carnot in 1824.

In 1895, Scottish mathematical physicist Peter Tait, an early historian of thermodynamics and associate of Thomson, defined dynamics as "a science that treats of the action of force upon matter, but which is, correctly, the science of matter and motion, or of matter and energy." [2]
