Types Of Vectors

Vector: A quantity that has magnitude as well as direction is called a vector.
Different types of vectors are,
a)  Zero or Null Vector: A vector whose initial and terminal points coincide, is called a zero vector (or null vector).
b) Unit vector: vector whose magnitude is unity (i.e., 1 unit) is called a unit vector.
c) Collinear Vectors: Two or more vectors are said to be collinear if they are parallel to the same line, irrespective of their magnitudes and directions.
d) Co-initial vectors:Two or more vectors having the same initial point are called coinitial vectors.

e) Negative of a Vectors: A vector whose magnitude is the same as that of a given vector, but direction is opposite to that of it, is called negative of the given vector.

f) Equal Vectors: Two vectors  are said to be equal, if they have the same
magnitude and direction regardless of the positions of their initial points,
