Distinguish between curvilinear motiom and rotational motion

Distinguish between curvilinear motiom and rotational motion.

Solution

In curvelinear motion, the particles moves along the curved path. Circular motion is one of example of many of curvilinear motions.In circular motion the particle rotates around a fixed circular curve , and whole the body rotates with respect to point outside the body. Any turning of an object, but there is no fixed axis with constantis constant. A toy train moving on a circular track is an example.

In rotational motion, the object rotates about an axis of rotation, that is lies either  passing through its body or outside the body of object that is that is spining. In the Eatth rotation, the rotates around an axis passing through north and sounth poles, motion of planets around the sun in a elliptical orbit are some examples.
