Whether the motion of a fan and motion of a cycle circular motion or rotatory motion?What's the differerces between circular motion and rotatory motion and give examples.?This is what the first source says;
Rotary motion is motion in a circle. The starting point for many mechanisms.
This is what the second source said;
In physics, circular motion is rotation along a circle: a circular path or a circular orbit. It can be uniform, that is, with constant angular rate of rotation, or non-uniform, that is, with a changing rate of rotation. The rotation around a fixed axis of a three-dimensional body involves circular motion of its parts. We can talk about circular motion of an object if we ignore its size, so that we have the motion of a point mass in a plane. For example, the center of mass of a body can undergo circular motion.
Therefore there is not difference between the two.
