Ever wonder why planes fly?
The wing of a plane is flat on the bottom and curved on top. Air particles are forced to go above or below the plane's wing. Although the distance to go over the plane's wing is longer than the distance to go under the plane's wing the particles reach the back of the plane wing at the same time. Therefore the particles travel above the plane wing are moving faster. With increased speed comes decreased pressure. Lower pressure on top of the wing and higher pressure beneath the wing causes the plane to lift. Voila.
Any questions?
