When a body is moving in a circular motion with constant speed, the direction of it continuously changes and hence velocity(v), momentum(p), and acceleration change because they are vectors and their direction changes. only as kinetic energy is a scalar, it remains constant.
When an object moves in a circle at a constant speed its velocity (which is a vector) is constantly changing. Its velocity is changing not because the magnitude of the velocity is changing but because its direction is. This constantly changing velocity means that the object is accelerating (centripetal acceleration).
