    Some times it becomes very difficult to differenciate between Circular motion and Rotational motion.Can any one tell me to understand clearcut diff. between the two?

    Rotational motion refers to an object rotating about an axis, like the daily rotation of the Earth. Circular motion if the motion of an object in a circular path, like the Earth traveling about the Sun each year.

    In circular motion, the body rotates with respect to a point outside the body. But in rotational motion, the body rotates to a point on the body.
    Each particle on the body undergo circular motion in a rotational motion.
