Types of Vectors | Vectors

1. Unit Vector

A vector having ‘unit’ magnitude is called a unit vector. It is denoted by $\hat{A}$. 

$\hat{i}$, $\hat{j}$, $\hat{k}$ are called rectangular unit vectors.

Unit vector along the vector $\vec{A}$ = $\frac{\vec{A}}{|\vec{A}|}$

2. Polar Vectors

Linear vectors are also called polar vectors. These vectors always directed towards some point.

e.g. force acceleration, velocity, etc.

3. Axial Vectors

Vectors that are associated with rotation about an axis are known as axial vectors.

e.g. torque, angular momentum, etc.

4. Null Vectors

Vectors having zero magnitudes are called null vectors, i.e. their tail and tip coincide with each other.
