Question

A quantity which can be completely represented by magnitude alone is called a ___________.

Answer 1

Scalar quantity:

1. A scalar quantity is defined as the physical quantity with only magnitude and no direction.
2. Such physical quantities can be described just by their numerical value without directions.
3. The addition of these physical quantities follows the simple rules of algebra, and here, only their magnitudes are added.
4. For example volume, density, speed, energy, mass, and time are scalar quantities.

Hence, a quantity which can be completely represented by magnitude alone is called a Scalar quantity.
