Bernoulli principle

The Bernoulli principle states that in a flowing fluid, such as air or water, an increase in speed occurs simultaneously with a decrease in pressure. Essentially, when fluid moves faster, its pressure drops; when it moves slower, pressure is higher. This explains many phenomena, like how airplane wings generate lift—air moves faster over the top of the wing, creating lower pressure and helping lift the plane. The principle highlights the relationship between fluid speed and pressure, revealing how energy transfers in moving fluids and influencing various practical applications.
