virial
1. A certain function relating to a system of forces and their points of application, first used by Rudolf Clausius in the investigation of problems in molecular physics.
2. In physics, half the product of the stress due to the attraction or repulsion between two particles multiplied by the distance between them.

Coined by the German mathematical physicist, Rudolf Julius Emmanuel Clausius (1822-1888), a founder of thermodynamics; including, major advances in electrolysis and kinetic theory of gases.

3. Etymology: from the stem of Latin vires, plural of vis, "strength"; and by extension, "force" or "energy".
