Bernoulli's Principle
Bernoulli's Principle states that in a flowing fluid, increased speed of the fluid is accompanied by a decrease in pressure. Imagine water flowing through a narrow pipe: as the pipe narrows, the water speeds up and the pressure inside the pipe drops. This principle explains various phenomena, such as how airplane wings generate lift—air moves faster over the top wing surface, creating lower pressure, which helps lift the plane into the air. Essentially, Bernoulli's Principle highlights the relationship between fluid speed and pressure in various applications, from engineering to nature.

Bernoulli's principle states that in a flowing fluid, an increase in the fluid's speed occurs simultaneously with a decrease in pressure or potential energy. This means that where fluid moves faster, the pressure within that fluid is lower. This principle is essential in understanding phenomena like how airplane wings generate lift, where air moving more quickly over the top of the wing creates lower pressure compared to the slower-moving air beneath the wing, resulting in upward force. Bernoulli's principle helps explain various applications, including airplane flight, fluid dynamics, and even everyday activities like drinking through a straw.
