Question

define velocity and mention it's unit​

Answer 1

Answer:

Rate of covering displacement in unit time in the given direction.

Velocity = displacement / time =m/sec = m/s

hence SI unit of velocity is m/s

Answer 2

The meaning of velocity of an object can be defined as the rate of change of the object’s position with respect to a frame of reference and time. It might sound complicated but velocity is basically speeding in a specific direction.

The SI unit of it is meter per second (ms-1)
