## Quick Reference

A vector that does not reverse its sign when the coordinate system is changed to a new system by a reflection in the origin (i.e. *x*′_{i} = −*x*_{i}). An example of an axial vector is the vector product of two polar vectors, such as *L* = *r* × *p*, where *L* is the angular momentum of a particle, *r* is its position vector, and *p* is its momentum vector. Compare pseudo-scalar.
