Four-vector — In relativity, a four vector is a vector in a four dimensional real vector space, called Minkowski space. It differs from a vector in that it can be transformed by Lorentz transformations. The usage of the four vector name tacitly assumes that… … Wikipedia
Four-force — In the special theory of relativity four force is a four vector that replaces the classical force; the four force is the four vector defined as the change in four momentum over the particle s own time::mathbf{F} = {dmathbf{P} over d au}.For a… … Wikipedia
