WebUsing the virial theorem: the mass of a cluster of galaxies The virial theorem postulates a simple relationship between the average kinetic energy and average gravitational potential energy of bodies in a gravitationally bound system: The right-hand side depends on some way on the mass of the WebVirial Theorem Simplest • 2T + U = 0 • By re-arranging the above equation and making some simple assumptions about T~(Mv2/2)) and U~(GM2/R) for galaxies one gets • M~v2R/G – M is the total mass of the galaxy, v is the mean velocity of object in the galaxy/cluster, G is Newton’s gravitational constant and R is the effective radius (size) of the object.

Velocity dependent forces and the Virial … WebThe Virial Theorem in Stellar Astrophysics Boltzmann equation that the virial theorem essentially arises from taking higher order moments of that equation. With that in mind let … The virial theorem has been generalized in various ways, most notably to a tensor form. If the force between any two particles of the system results from a potential energy V(r) = αrn that is proportional to some power n of the interparticle distance r, the virial theorem takes the simple form See more In mechanics, the virial theorem provides a general equation that relates the average over time of the total kinetic energy of a stable system of discrete particles, bound by potential forces (forces characterized exclusively by … See more Although the virial theorem depends on averaging the total kinetic and potential energies, the presentation here postpones the averaging to the last step.
