Instantaneous velocity is the velocity of an object at a specific moment in time. It is represented as the derivative of the position function with respect to time.

Instantaneous velocity can be found using the limit definition: $v(t) = \lim_{{\Delta t \to 0}} \frac{{\Delta x}}{{\Delta t}}$.
Graphically, instantaneous velocity is the slope of the tangent line to the position-time graph at any given point.
Instantaneous velocity is a vector quantity, meaning it has both magnitude and direction.
It differs from average velocity, which considers the total displacement over a time interval divided by that time interval.
In uniformly accelerated motion, instantaneous velocity can also be calculated using kinematic equations.
