Airplanes achieve flight through the interplay of four fundamental forces: lift, thrust, drag, and gravity. Wings generate ...

Daniel Bernoulli (1700-1782), demonstrated that, in most cases, the pressure in a liquid or gas decreases as the liquid or gas moves faster. This explains in part why a wing lifts an airplane.

It involves something known as 'Bernoulli's principle', which is worth further discussion. Bernoulli's principle is a description of how gases and liquids (fluids) behave. It says that within a ...
