Conservation of momentum differential form
Web1.2 Momentum conservation Newton’s law states that the rate change of linear momentum of a system is equal to the net force acting on a system. When applied to a CV, the rate of change of the CV momentum is given by the 1) the instantaneous time derivative of the CV momentum, plus 2) the net rate of transport of momentum across the CV … WebFor example, the stress–energy tensor is a second-order tensor field containing energy–momentum densities, energy–momentum fluxes, and shear stresses, of a …
