Question

How do we define velocity?

Answer 1

Answer:

Velocity is the ratio of displacement of an object per unit time, in a direction.

In other words, velocity as a vector quantity, is the ratio of the diplacement (distance with direction; hence it is also a vector quantity) of an object per unit time (time taken for the displacement of the object).

Its SI unit is same as speed, i.e., meters per second (m/s).

Its CGS unit is also same as speed, i.e., centimeters per second (cm/s).

Its formula is:

Velocity (v)=Displacement (S)/ Time (t)
