Notation | Vectors

A vector ‘A’ is denoted by an arrow sign on the top. (i.e. $\vec{A}$)

Physically, it is denoted by an arrow, where the tail of the arrow denotes the initial point and the tip denotes the terminal point.

——-> A

The length of the arrow tells us about its ‘magnitude’ and the tip of the arrow tells us about its ‘direction’.
