The 2<T> = - Sum(over k=1..N) < F(k) * r(k) > - <X> - X averaged over time
- T - Kinetic Energy
- F(k) - force on the kth object
- r(k) - position of the kth object
In a Gravity-bound system, this amounts to the time-averaged kinetic energy equaling the negative of the time-averaged potential energy of the objects. The theorem helps calculation of the average total kinetic energy in complex systems.
The terms - The radius and mass within that radius at which the Velocity Dispersion is maximal.
- The radius and mass within that radius within which virial equilibrium holds.
