Kinetic Energy of A Constrained Newtonian Dynamical System
Since the Euclidean structure of an unconstrained system of particles is entroduced through their kinetic energy, the induced Riemannian structure on the configuration space of a constrained system preserves this relation to the kinetic energy:
-
.(12)
The formula (12) is derived by substituting (8) into (4) and taking into account (11).

Famous quotes containing the words kinetic, energy, constrained and/or system:
“All my stories are webs of style and none seems at first blush to contain much kinetic matter.... For me “style” is matter.”
—Vladimir Nabokov (1899–1977)
“Long before Einstein told us that matter is energy, Machiavelli and Hobbes and other modern political philosophers defined man as a lump of matter whose most politically relevant attribute is a form of energy called “self-interestedness.” This was not a portrait of man “warts and all.” It was all wart.”
—George F. Will (b. 1941)
“An expansive life, one not constrained by four walls, requires as well an expansive pocket.”
—Anton Pavlovich Chekhov (1860–1904)
“In the course of the actual attainment of selfish ends—an attainment conditioned in this way by universality—there is formed a system of complete interdependence, wherein the livelihood, happiness, and legal status of one man is interwoven with the livelihood, happiness, and rights of all. On this system, individual happiness, etc. depend, and only in this connected system are they actualized and secured.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
