A free vector is a vector quantity having an undefined support or region of application; it can be freely translated with no consequences; a displacement vector is a prototypical example of free vector. Aside from the notion of units and support, physical vector quantities may also differ from Euclidean vectors in terms of metric.
Since the notions of vector length and angle between vectors can be generalized to any n-dimensional inner product space, this is also true for the notions of orthogonal projection of a vector, projection of a vector onto another, and rejection of a vector from another.
The Helmholtz decomposition in three dimensions was first described in 1849 [9] by George Gabriel Stokes for a theory of diffraction. Hermann von Helmholtz published his paper on some hydrodynamic basic equations in 1858, [10] [11] which was part of his research on the Helmholtz's theorems describing the motion of fluid in the vicinity of vortex lines.

When only the magnitude and direction of the vector matter, and the particular initial or terminal points are of no importance, the vector is called a free vector. The distinction between bound and free vectors is especially relevant in mechanics, where a force applied to a body has a point of contact (see resultant force and couple ).
LOS ANGELES (AP) — Dylan Andrews scored 21 points, Tyler Bilodeau added 18 and No. 18 UCLA extended its winning streak to nine games with a 111-75 victory over Prairie View A&M on Tuesday night.
Vector calculus or vector analysis is a branch of mathematics concerned with the differentiation and integration of vector fields, primarily in three-dimensional Euclidean space, . [1] The term vector calculus is sometimes used as a synonym for the broader subject of multivariable calculus, which spans vector calculus as well as partial differentiation and multiple integration.
NEW YORK (Reuters) -U.S. President-elect Donald Trump asked a New York judge on Monday to put off sentencing him on Friday for his criminal conviction stemming from hush money paid to a porn star.
The Dallas Cowboys requested permission to interview Philadelphia Eagles offensive coordinator Kellen Moore for their vacant head coaching position, multiple media outlets reported Thursday.
