# Virial theorem

The **virial theorem** is a feature of systems with central forces.

The overlines represent time averages. The right hand side is known as the virial of Clausius ^{[1]}. (Note: Herbert Goldstein uses for the virial ^{[2]}, however here we use for temperature, thus we use as per Hansen and McDonald^{[3]}).
