| الوصف: | In some previous articles, we defined several partitions of the total kinetic energy T of a system of N classical particles in the d-dimensional Euclidean space into components corresponding to various modes of motion. In the present paper, we propose formulas for the mean values of these components in the normalization T=1 (for any d and N) under the assumption that the masses of all the particles are equal. These formulas are proven at the "physical level" of rigor and numerically confirmed for planar systems (d=2) at N from 3 through 100. The case where the masses of the particles are chosen at random is also considered. The paper complements our article of 2008 [Russian J Phys Chem B, 2(6), 947-963] where similar numerical experiments were carried out for spatial systems (d=3) at N from 3 through 100. Comment: 34 pages, 4 figures, prepared for Functional Analysis and Other Mathematics |
