👉 Vitesses, in physics, refer to the rates of change or changes in velocity. They are quantities that describe how fast an object is moving relative to another reference point.
For example, if a car travels at 50 kilometers per hour (km/h) for 30 minutes, its speed is 50 km/h
30 min = 1500 km/h or 150 km/h. This means the car is moving at a rate of
