What is the primary difference between the motion of a ceiling fan and an oscillating table fan?

• Mass of the fan
• Color of the blades
• The nature of the rotational axis
• Speed of rotation

How does the axis of rotation behave in an oscillating pedestal fan?

• It remains completely fixed
• It moves freely in space
• It disappears periodically
• It moves sidewise but passes through a fixed point
