Unit Vector and Zero Vectors

Unit Vector

Any vector along with magnitude of 1, that is || u^→|| = 1, is called a unit vector.

Zero Vectors

The vector w^→ = (0,0) is called a zero vector as its components are all zero. Zero vectors are frequently denoted by 0^→. Be careful to differentiate 0 (the number) from 0^→ denotes the vector. The number 0 represents the origin in space, whereas the vector 0^→ denotes a vector that comprises no magnitude or direction.
