wat is the diffrence between circular and rotational motion??

DIFFERENCE BETWEEN CIRCULAR AND ROTATIONAL MOTION

CIRCULAR MOTION

{circular motion is associated with a centripetal force. Circular when the body moves around some other body}.For something to be ’circular motion,’ it just has to move in a circle. For example, a toy train on a circular track has circular motion.  if you were to pick a single point on the edge of the wheel, you could also say that it has circular motion.

ROTATIONAL MOTION

Rotational motion is associated with torque. Rotation is always when a body moves on its own axis .In general, a toy train on a track does not have an axis that it’s rotating around, so it would not have rotational motion. A wheel on a car, however, rotates around the car’s axle, so it does have rotational motion.

Maybe a better distinction to make would be between rotational motion and orbital motion. Even in that more generalized case (orbital could be something other than circular), the properties used to describe and analyze the motions are the same: axis of motion, angular momentum, moment of inertia, kinetic energy, torque, etc.

There is not a bold line of difference between the two, but generally, rotational motion refers to objects which are extended (not points) and spin about an axis which either within the material of the object or is not farther from the center of mass than the farthest dimension of the object.

Orbital (or "circular") refers to the motion of an object, which may or may not be spinning around an internal axis, around some point far from its center of mass and either repeats a path or nearly repeats a path (e.g., Mercury). More generally, the path doesn't even need to repeat because there are open orbital paths which astronomical objects routinely take.

One could say that rotational motion of a solid object is the orbital motion of thousands of particles, all moving about the same axis with the same angular frequency.

Don't get concerned about the distinction between rotational and orbital; it's not hard and fast. But you should be careful about using circular because that is very specific.
