instantaneous velocity

Instantaneous velocity describes the speed and direction of an object at a specific moment in time. It is a vector quantity, meaning it has both magnitude (speed) and direction.12

While average speed is calculated by dividing total distance by total time, determining instantaneous velocity is more complex. It requires calculus to find the exact rate of change at a precise instant. Approximations can be made by calculating average speed over increasingly shorter time intervals. For example, if an object travels 5 meters in one second, its average speed is 5 m/s. To find the instantaneous velocity, one would analyze the distance covered in fractions of a second to approach the exact speed at that moment. Acceleration is the rate at which velocity changes over time.134
