Unit vectors: a vector of unit length and is calculated by dividing the vector by its own magnitude. Null or Zero vectors: a vector with zero magnitude (zero length) and an unspecified direction. Negative vectors: two vectors having the same magnitude, but opposite directions. Under symbolic (also called Gibbs) notation, vectors are designated by
