Similarities between the motion of a bicycle and a ceiling fan:

(i) The blades of a fan and the wheels of a bicycle are fixed at a point.

(ii) Both have circular motion about their respective fixed points.

Differences between the motion of a bicycle and a ceiling fan:

(i) A bicycle has linear motion, whereas the blades of a ceiling fan do not have linear motion.

(ii) The motion of the blades of a fan is periodic, whereas the motion of a bicycle is rectilinear motion.
