Hi, I created this animation to give you a very easy, clear and logical understanding of playing with Pressure, Force and Area.
Pressure is the same inside a closed liquid but if you use a large area, you can get a large force, which is big enough to lift a car. This is the physics principle of a Hydraulic Jack. If you visit a local mechanic, you can see how a thin looking mechanic lifts a whole car.
This understanding leads to Bernoulli's equation.
