Dust cloud and energy momentum tensor

WebWe can express conservation of energy and momentum in terms of the stress-energy tensor. Recall that the physical meaning of the component Ttt is the energy density. To get the conservation laws, consider a small box with dimensions dx, dyand dz, and restrict our attention to the case of ’dust’, that is, a fluid WebOct 16, 2013 · and momentum in the EM eld can turn into energy of the charges and vice versa, and is therefore not conserved. The RHS of the = 0 component is minus the work done on the particles by the elds; the RHS of the = icomponent is minus the force (change in momentum per unit time) in the idirection exerted on the particles by the Maxwell eld.
