Question

Length is a __________________ (scalar/vector) quantity.

Answer 1

Scalar Quantities:

1. We know that to represent some physical quantities such as mass, length, time, density, speed, etc., only magnitude (unit and numerical value) is required.
2. There is no need for direction for the representation of these quantities.
3. Thus, those physical quantities which have only magnitude and have no direction are called scalar quantities.

Hence, length is a scalar quantity.
