Is it a spoiler or a wing?

[Normally but not always] The air goes above and below a wing, on spoiler the air only goes over the top. That makes sense?

That does make sense. I figured that one out when you mentioned nascar. But even though air flows below the spoiler on a car, you dont really want it to, right? Thats why they are angled the way that they are to force the car to the ground.

Turbulance is created when a blunt object cuts through the air, like mini tornado's...if you look at a wing in a wind tunnel you'll see that it smooths out the turbulance and reduces the cars drag. The top part of the wing is what creates the downforce.
