Question

What you necessarily need along with the magnitude of velocity to express it
thoroughly? (In one words)

Answer 1

The quantity that tells us how fast an object is moving anywhere along its path is the instantaneous velocity, usually called simply velocity. It is the average velocity between two points on the path in the limit that the time (and therefore the displacement) between the two points approaches zero.
