Virial (disambiguation)

The virial of a central interaction potential Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle v(r)} is defined by

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

Apart from historical reasons, the virial features prominently classical thermodynamics (for example, see virial coefficients) and in simulation (see: virial pressure).
