The velocity of the car that remains constant throughout its motion, even after it comes to a stop for some time and then resumes, is called the "constant velocity."
Constant velocity refers to a situation where an object's speed (magnitude of velocity) remains unchanged, and its direction also remains constant. In this case, the car starts with a certain constant velocity, comes to a stop, and then continues with the same constant velocity. Regardless of the pause in motion, as long as the speed and direction of the car remain unchanged during its travel, it is still considered to have a constant velocity.
