A simple answer to this question is that the wind is a kind of force. We know the matter from primary school. Well, what does it mean to say this, I mean, can it really be felt?
First of all, I will tell an incident from which the matter can be felt much better. Nowadays, we do not have a single moment without a hot fan. Well, have you thought about why the wind blows when the fan rotates?
Of course, it doesn't come from inside the fan!
Why? I believe everyone has caught it. There is no air in the room, no matter if the fan is turned on or not!
Many people have noticed that each of the fan's wings is a little dull. That means there must be air in the place where the fan is installed, and when the fan rotates, the wings push the air down in that place! And the wind blows on us!
You can do one thing. Collect an electric pea and attach it with a battery and a switch. Then collect a thick piece of paper with the mouth of a bottle. Now drill a hole in the mouth of the bottle and attach it to the pea. Cut the paper in the shape of a fan used at home as a paper facility).
Then open the fan and put in a little bit and you will see that the wind is blowing. If you are sitting under the fan now, then notice the matter. You will understand very well!
