If it is a 70 MPH per hour wind and you drive your car at 70MPH downwind...?

Question

If you stick your head outside the window would you feel the wind?

Answer 1

In theory no, but in reality yes, because the shape of your car would create additional air turbulance. It would be this that you felt.

Answer 2

Based on what you describe and treating it as a thought experiment, no, you don't feel any wind because you are moving along with the wind. The molecules of air and you are moving at the same speed and in the same direction.

Here is a similar question for you to ponder:
A large hot air balloon is being carried due east by a steady wind. Which direction does a scarf hanging from the gondola sway? It doesn't. As far as the people in the balloon are concerned, there doesn't seem to be any wind.

Answer 3

If the wind was blowing perfectly straight at a constant speed, then no, you wouldn't feel it since the air is moving at the same speed you are.

This is why airplanes take off and land going into the wind. If the velocity of the plane is the same as the air, then it would be as if the plane was sitting still in midair. That would be bad news because no air moving across the wings = crash and burn.

Answer 4

If you ignore the aerodynamics of the car, you would not feel the wind as the car would be travelling the same speed and direction as the wind.

In reality, cars are designed to push air away from them, so you'd feel wind at any speed. Not to mention the constant changes in wind speed and direction. It would be next to impossible to simulate this problem IRL.

Answer 5

Assume:
no speed variation in either.
exactly the same verlocity (a vector) of the car and wind
no feedback turbulance from the car and wind settling to same verlocity.

Then yes but only as much as you know air surrounds you under no net movement (air is constantly moving on the atomic scale but overall is view not moving).

Answer 6

Dear James
If v r talking theritical way u ll not feel any wind coz both speeds r equal and in one direction but practically u know speed of wind is not constant so probably u feel wind`s effect on ur face.
Good luck

Answer 7

It doesn't have to be so fast, have you ever run into a six MPH wind and then turned round and ran back, if you judge your speed right you will find you are running in apparently still air.

Answer 8

as car moves it will deflect a volume of air equal to its own volume around the outside of car (nop matter wind speed) so u would be creating eddy currents - at very least - that u'd feel with head stuck out of window.
always try experimentaly though

Answer 9

Yes, if you stick your head out at a high rate of speed. Otherwise, no

Answer 10

Of course you would.
Wind speed is an average of gust speeds.
The wind is not constant like a car speed can be.
