Proof of virial theorem
WebThe 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. 2T + U = 0 By re-arranging the above equation and making some simple assumptions about T (=) and U (=) for galaxies we obtain: WebVirial theorems also are applicable to stars where the kinetic energy is the thermal energy of all gas particles. Quantum systems also obey the virial theorems. – 3 – 3. Masses of …
