Aviation Physics 101: In aviation, Bernoulli's Principle is key to understanding how planes generate lift—a force essential for flight. Named after Swiss mathematician Daniel Bernoulli, this principle explains that as the speed of a fluid (like air) increases, its pressure decreases. Take an airplane wing, or "airfoil": its curved top and flatter bottom cause air to move faster over the top, creating lower pressure above the wing and higher pressure below. This pressure difference produces lift,

Bernoulli’s principle describes how a fluid moves faster when it passes through a narrow space, causing the pressure in that area to drop. When a stream of compressed air is directed around a screwdriver, the moving air creates a region of lower pressure compared to the still air around it. This pressure difference produces lift, allowing the screwdriver to rise and stabilize as if it is floating. It is a simple but powerful demonstration of how fluid motion shapes the forces we observe. This sa
