Circular motion and rotational motion are related but have distinct differences:
1. Circular motion: Circular motion refers to the movement of an object along a circular path. In circular motion, the object continuously moves around a fixed point or axis. The object maintains a constant distance from the center of the circle, and its speed may be constant or varying. Examples of circular motion include the motion of a satellite around the Earth or the motion of a car around a racetrack.
2. Rotational motion: Rotational motion, on the other hand, involves the spinning or rotation of an object around its own axis. In rotational motion, the object rotates around an internal axis, rather than moving along a circular path. The axis of rotation remains fixed, and the object rotates in a circular or curved manner around that axis. Examples of rotational motion include the spinning of a top or the rotation of the Earth on its axis.
In summary, circular motion involves an object moving along a circular path, while rotational motion involves an object spinning or rotating around its own axis.
In rotational motion, the axis of rotation and centre of mass could change whereas in circular motion, the axis of rotation and centre of mass does not change.
The major difference between circular and rotatory motion is that in circular motion, the body rotates around a fixed axis that is outside the body, but in rotational motion, the body's rotating axes are inside the body.
