Pressure is force per unit area. This simple concept powers hydraulic machinery, explains weather, and determines whether objects implode under water.
The Formula
P = F ÷ A | Hydraulic: small area input amplifies force on large area output
Standard formula used by professionals worldwide
Worked Example
Step-by-step
Hydraulic jack: 100N on 0.001m² = 100,000 Pa → on 0.01m² output → 1,000N output (10× force)

Frequently Asked Questions
Pascal's Law?
Pressure in confined fluid transmits equally in all directions. Foundation of all hydraulic systems.
Ocean floor pressure?
At 10,000m depth approximately 100 MPa — 1,000 times atmospheric pressure.
Tyres and pressure?
Under-inflated tyres create more contact area, increasing rolling resistance and fuel use.
