Question

what do you understand by the term magnitude ?​

Answer 1

In physics, speed is a pure scalar, or something with a magnitude but no direction --such as 5 m/s. 5 meters per second does not tell us which way the object is moving. ... All that we know from the speed is the magnitude of the movement.

Answer 2

Magnitude is a scalar quantity; it refers just to the size of some quantity. For example quantities like mass, volume, density, distancec only have magnitude, so they are scalars. Now quantities like force, velocity, field have magnitude (size) and direction. These are vector quantities
