Learn about fluid pressure in this 16-minute AP Physics video from Khan Academy. Explore the concept of pressure as the perpendicular force exerted per unit area over a surface, and understand why it's considered a scalar quantity rather than a vector. Discover how pressure in incompressible fluids increases with depth and the relationship between absolute and gauge pressure. The video breaks down complex physics concepts into clear sections covering the definition of pressure, its scalar nature, pressure changes with depth, and the distinction between absolute and gauge pressure measurements. Part of Khan Academy's comprehensive free educational resources, this video serves as an excellent introduction to fluid mechanics principles.
