Forces in Fluids: Pascal's Principle

The video explains how pressure applied to a confined liquid is transmitted equally in all directions, as demonstrated by Blaise Pascal's principle. This principle is crucial in hydraulic systems, which use liquids to transmit pressure, such as in car brakes. When the brake pedal is pressed, pressure is applied to brake fluid, which is then transmitted through the system to stop the car. Pascal's principle allows for the multiplication of force, enabling efficient operation of various machines and devices.
