Question

No.of revolutions when fan is switched off

Answer 1

Dear mate,
Kindly mark the answer as brainliest if you find it useful.

Here's what you were looking for:

The fan rotates even after it is switched off because of first law of motion i.e. The law of inertia.

To put it in simple words, it says Any body continues to be in a state of motion or rest until and unless acted upon by an external force.

When we switch off the fan ,the fan blades which are in motion wants to remain in motion. But due physical constraints like friction they stop after a few revolution. However in vacuum if we switch off the fan if will keep rotating as there is no friction.

Hope this clears your doubt.✌
