We know that scalar and vector quantities are very important for every physics and maths exams.

Scalar


 A quantity having only magnitude is called Scalar. eg.- distance, speed etc

Vector


A quantity having both magnitude and direction. A vector is represented by an arrow. The length of the arrow gives the magnitude of the vector and the direction of the vector. 

Notation- it is generally represented by A vector or A.

Example- Displacement, Velocity, Force etc.
