Vedclass · Answer

(B) Average velocity provides information about the motion of an object over a finite time interval,but it does not tell us how the object is moving at any specific moment within that interval.In many real-world scenarios,the velocity of an object changes continuously.To understand the state of motion at a precise moment,we define instantaneous velocity.It is defined as the limit of the average velocity as the time interval $\Delta t$ approaches zero: $v = \lim_{\Delta t 	o 0} \frac{\Delta x}{\Delta t} = \frac{dx}{dt}$.Therefore,it is used to describe the motion of an object at a specific instant of time.
