(N/A) Instantaneous velocity is defined as the velocity of an object at a specific instant of time or at a specific point in its path.
Mathematically,it is the limit of the average velocity as the time interval $\Delta t$ approaches zero.
It is expressed as: $v = \lim_{\Delta t \to 0} \frac{\Delta x}{\Delta t} = \frac{dx}{dt}$.
Here,$dx$ is the infinitesimal displacement and $dt$ is the infinitesimal time interval.
Graphically,the instantaneous velocity at any point on a position-time graph is equal to the slope of the tangent drawn to the curve at that specific point.
