What is magnitude?
Asked by rohanganu | 30 May, 2009, 10:37: PM
answered-by-expert Expert Answer

The magnitude of a object is its size: a property by which it can be larger or smaller than other objects of the same kind; in technical terms, an ordering of the class of objects to which it belongs.

A scalar is a variable that only has magnitude, e.g. a speed of 40 km/h. Compare it with vector, a quantity comprising both magnitude and direction, e.g. a velocity of 40km/h north.
