This document discusses Bernoulli's principle and its application to flight. It explains that Bernoulli's principle states that the pressure exerted by a moving fluid decreases as the fluid's velocity increases. The Wright brothers were the first to achieve powered flight using this principle. Airplanes and helicopters are able to fly through the lifting force generated by the differences in pressure above and below their wings or rotors as the fluid (air) flows around them. The document also briefly discusses fluid dynamics in baseball pitching and car engines.
