In vector spaces with an inner product for which the requirement of positive definiteness has been dropped, a vector that has zero length is referred to as a null vector.

Vector Motors , seeing the slow sales of the expensive Vector M12 M12 , decided to design a new car that would be easier and cheaper to build and sell. The outcome was the SRV8, essentially a modified Vector M12 M12 . The chassis came from one of the racing M12 s which ran at Road Atlanta in 1998 and featured small changes such as moved suspension pickup points. The biggest difference though was the engine. Vector decided to ditch the Lamborghini V12 that the Vector M12 M12 used, returning to the company s American roots with a GM LT engine GM LT1 V8 engine , basically the same as used in the Chevrolet Corvette and a Porsche G50 transaxle .

Formally, given a vector field v , a vector potential is a vector field A such that math mathbf v nabla times mathbf A . math If a vector field v admits a vector potential A , then from the equality math nabla cdot nabla times mathbf A 0 math divergence of the Curl mathematics curl is zero one obtains math nabla cdot mathbf v nabla cdot nabla times mathbf A 0, math which implies that v must be a solenoidal vector field . An interesting question is then if any solenoidal vector field admits a vector potential.

Unreferenced date November 2009 A two vector is a tensor of type 2,0 and it is the dual space dual of a two form , meaning that it is a linear functional which maps two forms to the real numbers or more generally, to scalars . The tensor product of a pair of Vector geometric vector s is a two vector. Then, any two form can be expressed as a linear combination of tensor products of pairs of vectors, especially a linear combination of tensor products of pairs of basis vectors. If f is a two vector, then math mathbf f f alpha beta , vec e alpha otimes vec e beta math where the f sup sup are the components of the two vector. Notice that both indices of the components are covariance and contravariance contravariant . This is always the case for two vectors, by definition. An example of a two vector is the inverse g sup sup of the metric tensor . The components of a two vector may be represented in a matrix like array.

The magnitude is unitless . For Kepler orbits the eccentricity vector is a constant of motion.

pp semi indef The mass vector is a vector quantity that describes the magnitude and direction in which the mass acts for any point mass in the known universe in its movement about the universe s central axis of rotation. The discovery of the mass vector is commonly attributed to Isaac Newton Sir Isaac Newton and is documented in a recently recovered chapter of his treatise De motu corporum in gyrum . ref De motu corporum in gyrum ref The mass vector is defined as the resultant vector of the division of the force vector by the acceleration vector or the derivative with respect to position of the dot product of momentum and time, which is referred to as the Hang and abbreviated . Very little is yet understood about the properties of mass vectors because they are hypothesized to exist only within the singularity of black holes where the extreme gravitational force compresses acceleration to a scalar quantity. There is some controversy regarding the definition of the mass vector, as seen in James Clerk Maxwell s treatise James Clerk Maxwell Later years Matter and Motion . Maxwell defines the mass vector as follows ... a mass vector is ... the operation of carrying a given mass from the origin to the given point. The direction of the mass vector is the same as that of the vector of the mass, but its magnitude is the product of the mass into the vector of the mass. Thus, if OA is the vector of the mass A, the mass vector is OA A. However, this definition does not take modern quantum theory into account, and is commonly considered to be obsolete. ref http www.physicsforums.com archive index.php t 3364.html ref Mass Vector Criticisms Although many physicists agree on the details of mass vectors, there are still some debates. ref http en.wikipedia.org wiki Two New Sciences ref Many critics believe that mass vectors are in direct contrast to Galileo s classic idea of Falling Bodies.
