What is the motion of an object in which its speed is constant but the velocity is changing?

To summarize, an object moving in uniform circular motion is moving around the perimeter of the circle with a constant speed. While the speed of the object is constant, its velocity is changing. Velocity, being a vector, has a constant magnitude but a changing direction.

An object moving in uniform cicular motin is moving around the perimeter of the circle with a consant speed while the speed of the object is constant ist velocity is changing velocity being a vector has a constant magnitued but a changing direction . thank you
