Question
Which of the following has no gravitational force involved?
- The motion of a seesaw
- The motion of a swing
- The motion of the blades of a fan
- The motion of a slide
Hint:
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.
