1.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
2. This explains why an object moving in a circle at constant speed can be said to accelerate - the direction of the velocity changes.
3.The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion.
4.In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities. The orientation of an object's acceleration is given by the orientation of the net force acting on that object.

Answer:
1. the speed of the of object is decreasing. the speed of the A point is just a half of B point and the speed of B point is just a half of C point.
2. the movement of the object around the circle is moving clockwise.
3. the velocity of the object is increasing.
4. the range of speed of velocity of the object is moving in perfect multiplication of speed from point A to point C.
