when an object is rotating in a circle and the only force is acting on it is friction how is force of friction vector pointing towards the circle because an object in circular motion is traveling in that direction, it's accelerating towards the center of the circle, but friction is suppose to appose motion... and if motion is towards the center of the circle how could friction alos be if it's suppose to oppose motion

Friction is not towards the center, it is directed against the motion, tangentially.

Now for motion in a circle. Motion in a circle is NOT directed towards the center, or it would spiral inward. In a constant radius circle, ACCELERATION is directed inward, and that is why the object does not travel in a straight line.
