Circular motion:
A particle, when it moves in a trajectory or in a circular shape, is said to be in a Circular motion. For example, imagine a rock tied to one end of a rope and the other end of the rope tied to your hand. Now if you swing the system, the rock will follow a in a circular trajectory and the motion is now circular.
Rotational motion:
However, in a rotational motion, an object moves around an axis that passes through its body. The best example would be the rotation of the Earth. It rotates around an axis passing through both of its poles(north pole and south pole). While rotating, each point on the object will follow a circular trajectory and hence will undergo circular motion.
