Newton's laws control how cars work, how water flows, how buildings don't fall down, and basically how everything around us moves. ... It is this force which pushes the car forward

Answer:
Now here, according to your question, the fan here is the rigid body and the rigid body is in motion when the switch is turned on. When the fan is off, a rotational inertia acts on the rotating fan. Due to this rotational inertia, the fan rotates; H. its wings move and rotate until an external force is applied. And since a friction force acts on the rotating fan blades due to the air, the speed of the fan blades stops and finally stops. Air friction is the external force that stops the fan blades after a while, otherwise they would never have stopped rotating.
