Virial (disambiguation): Difference between revisions

Revision as of 09:42, 7 October 2010

The virial of a central interaction potential $v (r)$ is defined as

V (r) = \frac{d v (r)}{d r} r = - f (r) r .

The virial features prominently in classical thermodynamics (for example, see virial coefficients) and in simulation (see: virial pressure).
