Pascal's Principle

Pascal's Principle states that when you apply pressure to a confined fluid, that pressure is transmitted equally throughout the entire fluid and to all surfaces of its container. This means any change in pressure at one point in the fluid spreads everywhere, allowing small forces to generate larger forces elsewhere—a principle used in hydraulic systems like car brakes or lifts. Essentially, it shows how fluids transmit force efficiently, enabling devices to amplify force or perform tasks more easily, all while contained within a sealed system.
