Abstract

THE term “vector” is used to include two distinct classes of geometrical and physical entities. A polar vector, typified by a displacement or a mechanical force, is a magnitude associated with a certain linear direction. The members of the second class, that of axial vectors, are primarily not vectors at all. An axial vector exemplified by a statical couple, is a magnitude associated with a closed contour lying in any one of a system of parallel planes. Two senses of direction are distinguished, both for polar and axial vectors.
