Detailed Solution

Circular motion is described by the point marked on the blade.[14]
A ceiling fan blade will rotate at a constant speed for a point marked on it. This results in two points: The first is the circular motion caused by the rotation of the ceiling fan blades and thus of the point marked on the blade. The second point is that it rotates at a steady speed.
As a result, it is a circular motion.
