Uniform Velocity is also known as constant velocity. It means that the object’s velocity is not increasing or decreasing. In other words, the object is not accelerating or decelerating.
When an object is traveling at constant velocity, it travels the same distance for every unit of time.
In this slide, we have a car travelling at constant velocity. It travels a distance of 10m every second. Hence its displacement from the traffic light increases at a constant rate of 10m every second.
