Virial (disambiguation): Difference between revisions

Revision as of 11:42, 7 October 2010

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

V(r)={\frac {dv(r)}{dr}}r=-f(r)r.

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