The direction of the movement changes.
Explanation:
Velocity is not only a quantity telling you how fast you are going, for instance in meters per second. It also tells you in what direction something is moving. Velocity is a so called vector, an object with both a direction and a magnitude (and as a vector you can add them up in a certain way, but that's not really relevant here).
For a circular or curved path, the magnitude of the velocity can be constant, but the direction certainly isn't. If the direction of the velocity is constant, that would mean the object would be travelling along a straight line.
