Some of the types of vector are as follows:

1. Column vector: The vectors whose x and y components are arranged vertically as in (x, y) is called column vector.
2. Row vector: The vector whose x and y - components are arranged horizontally as in (x, y) is called row vector. A vector can be expressed either in a row vector or in a column.
3. Position Vector: The vector whose initial point is taken as the origin is called position vector.
4. Unit Vector: The vector whose magnitude of length is unity i.e. 1 is called the unit vector.
5. Null or Zero vector: The vector whose length or magnitude is zero is called zero or null vector.
6. Equal vector: Two vectors are said to be equal is they have the same magnitude and direction.
7. Negative vector: The two vectors whose magnitude is same but are in opposite direction are called negative vectors.
8. Parallel vectors: Two vectors are said to be parallel of both of them have either same or the opposite directions whatever may be their magnitudes.
9. Like vectors: Two vectors are called like vectors if they have the same direction regardless of their magnitudes. $$\overrightarrow{a}$$ and $$\overrightarrow{b}$$ are two like vectors then we can write $$\overrightarrow{a}$$ = k $$\overrightarrow{b}$$ where k is a scalar quantity.
10. Unlike vectors: Two vectors are called unlike vectors if each vector has the opposite direction.
