Question

Stress-energy tensor of point particle when the trajectory is a transcendental equation?

Answer 1

The stress–energy tensor, sometimes stress–energy–momentum tensor or energy–momentum tensor, is a tensorquantity in physics that describes the densityand flux of energy and momentum in spacetime, generalizing the stress tensor of Newtonian physics. It is an attribute of matter, radiation, and non-gravitational force fields. The stress–energy tensor is the source of the gravitational field in the Einstein field equations of general relativity, just as mass density is the source of such a field in Newtonian gravity.

Answer 2

Explanation:

The stress–energy tensor is defined as the tensor Tαβ of order two that gives the flux of the αth component of the momentum vector across a surface with constant xβ coordinate. In the theory of relativity, this momentum vector is taken as the
