Question

It is about physics. Differences between circular and rotational motion

Answer 1

Answer:

The main difference between these types of motion is that circular motion is a special case of rotational motion, where the distance between the body’s centre of mass and the axis of rotation remains fixed.

Rotational motion is based around the idea of rotation of a body about its center of mass. 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.

Circular motion is a movement of an object along the circumference of a circle or rotation along a circular path and can either have a constant angular rotation rate and constant speed, or it can exist with a changing rate of rotation.

In a circular motion, the axis of rotation is inside the body, while the axis of rotation in the other case, may be outside.

Circular motion is the motion of a body around a fixed point where the point lies outside the body.In rotational motion the point lies inside the rotating body. Circular motion is the cause of centripetal force while rotational motion is due to torque acting on the body.
