Normalizing A Vector. To normalize a vector, therefore, is to take a vector of any length and, keeping it pointing in the same direction, change its length to one, turning it into what is referred to as a unit vector. Being able to quickly access the unit vector is useful since it describes a vector's direction without regard to length.

Being able to quickly access the unit vector is useful since it describes a vector's direction without regard to length. In geometry, various formalisms exist to express a rotation in three dimensions as a mathematical transformation.in physics, this concept is applied to classical mechanics where rotational (or angular) kinematics is the science of quantitative description of a purely rotational motion.the orientation of an object at a given instant is described with the same tools, as it is.
