1. Vector quantities refer to the physical quantities characterised by the presence of both magnitude as well as direction.
2. The term also denotes the mathematical or geometrical representation of such a quantity.
3. A vector with the value of magnitude equal to one is called a unit vector and is represented by a lowercase alphabet with a “hat” circumflex i.e. “$\hat{u}$“.
4. For example, displacement, force, torque, momentum, acceleration, and velocity, are vector quantities.
