Question

What is magnitude? With example

Answer 1

The magnitude is the size of a quantity which can be measured. For example, speed of car is 20km/h then its magnitude is 20 and its unit is km/h.

Answer 2

On the other hand, velocity, in Physics, must be expressed as a vector with both a magnitude and a direction. For instance, 5 m/s Eastward is a velocity because it tells you the magnitude of the movement, 5 meters per second, as well as the direction which is Eastward.
