A physical quantity that has magnitude only is called

Explanation:
A quantity described by a magnitude alone is a scalar. Scalars have size but no direction, so you can describe them with just a number and units. Think of mass, temperature, time, or distance—these have how much there is, but not which way something is moving. A vector, by contrast, has both magnitude and direction, so you must specify orientation in addition to size and use vector addition that accounts for direction. That’s why the description “magnitude only” points to a scalar.
