Four-tensor is a frequent abbreviation for a
In order to avoid notational and conceptual confusion, it is common to call the 4-dimensional energy-momentum tensor () the 4-momentum of an object so as to not be confused with the spacial 3-momentum .

Tensor — For other uses, see Tensor (disambiguation). Note that in common usage, the term tensor is also used to refer to a tensor field. Stress, a second order tensor. The tensor s components, in a three dimensional Cartesian coordinate system, form the… … Wikipedia
Tensor contraction — In multilinear algebra, a tensor contraction is an operation on one or more tensors that arises from the natural pairing of a finite dimensional vector space and its dual. In components, it is expressed as a sum of products of scalar components… … Wikipedia
Four-momentum — In special relativity, four momentum is the generalization of the classical three dimensional momentum to four dimensional spacetime. Momentum is a vector in three dimensions; similarly four momentum is a four vector in spacetime. The… … Wikipedia
Stress-energy tensor — The stress energy tensor (sometimes stress energy momentum tensor) is a tensor quantity in physics that describes the density and flux of energy and momentum in spacetime, generalizing the stress tensor of Newtonian physics. It is an attribute of … Wikipedia
