5- Instantaneous speed | Animation Physique | Physics Animation |

The driver looks at the speedometer, he finds that the indication varies from one moment to another.
The value given by the speedometer of the car is the instantaneous speed of the car.
The speedometer allows the driver to know the instantaneous speed of the vehicle.
