The velocity v is a vector that describes how fast an object is moving, and in which direction.



if we consider v as velocity and x as the displacement vector, then we can express the instantaneous velocity of an object, at any particular time t, as the derivative of the position with respect to time


Example 1

If you drive 30 km on a bicycle in 2 hours, you can calculate the velocity as 30 / 2 = 15 km/h.
