VECTORS-

Physical quantity having both magnitude and direction called vector quantity . And the physical quantity having magnitude only called scalar quantity . E.X.- suppose a man move 10 km , now in that case I am discussing about  its distance only i.e. it has magnitude only but there is no any information about its direction hence it is a scalar quantity, if we say man  is moving 10 km towards East(or any other direction ) so we can say we are discussing about its displacement i.e. it has both magnitude and direction. A vector quantity is represented as an arrow on its top ex;-  ? ⃗

Vectors can be divided into two ways –

  • Polar vector- a vector which has a starting point or a point of application. E. X .- displacement , force etc.
  • (ii) Axial vector – Vectors which represent rotational effects and acts along the axis of rotation in accordance with right hand screw rule.
