Document Summary
If you were to take a 747 (huge plane) and were to put it on its tail end. We reduce the amount of thrust coming from engines and make huge wings to lit. The weight is diferent the mechanism of the ground. Even a paper airplane can change drasically in the amount of drag and lit it produces. Paper airplane lying contest didn"t do very well but was fun . Fluid lit force is dictates by bernoulli"s principle all about pressures. What happens when the low of a luid goes around something shaped like an airfoil. Cannot be symmetrical otherwise no lit will be created. There has to be a diference in low on top of air foil and underneath for lit to be maintained. Diference in luid velocity (with respect to each other) that creates the high and low pressures. Underneath wing = low low velocity, high pressure.
