Instantaneous velocity

Knowing the concept of average speed, you might ask yourself, “But does the car have to travel all the way at a speed of 60km / h?”

The answer is no, because the average speed averages the speed during the course (although it is not a weighted average, such as a race average).

So the speed the car speedometer shows is the instantaneous speed of the car, that is, the speed the car is at the moment you look at the speedometer.

The instantaneous velocity of a mobile will be found when considering a time interval () infinitely small, ie when the time interval tends to zero ().

To perform the instantaneous velocity calculation, ie when the time interval is very close to zero, a derivative calculation is used:
