Hello student,

Scalar Quantity

A scalar quantity is a physical quantity that has only magnitude and no direction. Examples of such quantity are volume, density, speed, energy, mass, and time. It can be described by a single element of a number field such as a real number

The quantity that have both magnitude and direction is called a vector quantity. Examples are force, velocity etc.

Thank you.
