Definition: quantity which can be represented by a vector multiplied by a scalar quantity

Note 1 to entry: The vector defining a vector quantity is generally a unit vector in the usual two- or three-dimensional geometrical space. A vector quantity can then be represented as an oriented line segment characterized by its point of acting, its direction and its magnitude, where the magnitude is a non-negative number multiplied by a unit of measurement. The components are also the product of a numerical value and the unit. Examples of vector quantities are: velocity, force, electric field strength.

Note 2 to entry: A vector quantity may be considered either as attached to a point of acting (localized or bound vector), or as having any point of acting on a straight line parallel to it (sliding vector), or as having any point of acting in the space (free vector).

Note 3 to entry: Operations defined for vectors apply to vector quantities. For example, the product of a scalar quantity p and the vector quantity Q=qe MathType@MTEF@5@5@+= feaagKart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHX garuavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGe aGqk0di9Wr=fpeei0di9v8qiW7rqqrVepeea0xe9LqFf0xc9q8qqaq Fn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpe WZqaaeaaciWacmGadaGadeaabaGaaqaaaOqaaKqzafGaaCyuaiabg2 da9iaadghacaWHLbaaaa@3D40@ is the vector quantity pQ=pqe MathType@MTEF@5@5@+= feaagKart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHX garuavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGe aGqk0di9Wr=fpeei0di9v8qiW7rqqrVepeea0xe9LqFf0xc9q8qqaq Fn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpe WZqaaeaaciWacmGadaGadeaabaGaaqaaaOqaaKqzafGaamiCaiaahg facqGH9aqpcaWGWbGaamyCaiaahwgaaaa@3F2A@ , where e is a unit vector.
