The virial theorem of Clausius was developed by Clausius in 18707 and the ratio of the average kinetic energy to the average potential energy of a mechanical system was established.
What does the virial theorem tell us?
The virial theorem relates the total kinetic energy of a self-gravitating body due to the motions of its constituent parts, T to the gravitational potential energy, U of the body. ... Consequently, the virial theorem forms the root of many galaxy scaling relations.
What is virial theorem in classical mechanics?
Statement of the Virial Theorem: For the n point particles bound together into a system the time average of the kinetic energy of the particles, Σ½mivi², plus one half of the time average of ΣFi·ri is equal to zero.
