Similarities

1) Both are undergoing rotational motion.

2) The distance of any point on the wheel or ceiling fan from the center of wheel or ceiling fan respectively will remain constant.

Differences

1) The ceiling fan is doing only rotational motion, whereas wheel is doing the translational and rotational motion.
