Physics Uncovered on Instagram: "Pascal’s principle (also called Pascal’s law) states that when pressure is applied to a confined fluid, that pressure is transmitted equally in all directions throughout the fluid and to the walls of its container. In simple terms, if you push on a fluid in a closed system, the same pressure increase happens everywhere inside it. This is the principle behind hydraulic systems like car brakes, lifts, and presses. For example, when you push a small piston in a hydr
