1Similarities: Wheel of a bicycle and ceiling fan (when on) both show circular motion.
Differences: Cycle moves in rectilinear motion.
2The motion of a bicycle is in rectilinear motion, the object covers a certain distance along a straight line or a track. Whereas the motion of a ceiling fan when switched on is in circular motion, which is not moving from one place to another.The circular motion of the wheel gives the bicycle a rectilinear motion and the periodical motion of a blade of a fan gives the fan a circular motion. If marked in a point on the wheel of a bicycle or a blade on the fan, the distance between the centre of the wheel/fan and the marked point will remain the same as they rotate.
3Similarity:- Both ceiling fan and bicycle exhibit circular motion.
Difference:- Bicycle shows rectilinear motion while ceiling fan does not.
4Similarities in the motion of a bicycle and a ceiling fan that is switched on is both are in moving(Running) position.
Bicycle run in rectilinear motion
