consider this:
you are traveling exactly 60 KM/H going exactly south in a car
there is a wind traveling exactly 60 KM/H going exactly south
if you stick your hand out, what would you feel?

we are moving relative to everything around us, so should we not feel no force at all?
take into account there is nothing blocking this wind nor speeding up/slowing it down, its exactly the same speed your car is traveling.

help meeee

I assume you would feel the force caused by the car traveling through air (Drag)

But, the car is moving relative to the wind, so there would be no drag

Atmospheric drag is not just caused when traveling against wind as far as i know. It is caused while traveling through air itself (which happens to be all around us).

Of course i could be wrong so don't take my word on it. It's just what i conclude from what i personally know (Which is not very much)

But what happend when your moving relative to the wind, instead of against it?

drag happens when you are pushing air out of the way. if it is going the same direction at the same speed there would be no drag.

think about the drag when swimming downstream, basically the same effect.

so then, you would feel nothing?

Is drag not caused by the friction of an object moving through a fluid (air in this case)? (The air seperates at the front of the object and flows around the vehicle?) - this of course is just my understanding of drag, i could be wrong so its why im posting here, hopefully someone will enlighten me.

yes, you are right, but with the vehicle moving relative to the wind around it, would it not be that in a way, the wind is our vessel, and everything inside it is relative to us?
