Question

Which of the following has no gravitational force involved?

  1. The motion of a seesaw
  2. The motion of a swing
  3. The motion of the blades of a fan
  4. The motion of a slide

hintHint:

The motion of the blades of a fan has no gravitational force involved.

The correct answer is: The motion of the blades of a fan


    This is the motion of a body as it rotates about an axis within itself. It can be said to be the motion of a body as it circulates about a point in itself.
