): The contact surface area over which the force is applied. 2. Units of Measurement
Dam bases are built thicker at the bottom to withstand higher water pressure at greater depths.
Force per unit area is the fundamental definition of . It describes how a force is distributed across a specific surface, influencing how objects interact, such as why a sharp knife cuts easily or why snowshoes prevent sinking. 1. Mathematical Definition The relationship between pressure ( ), force ( ), and area ( ) is expressed by the formula:
Force, Area & Pressure | Difference, Applications & Examples
Uses Pascal's Principle to transmit pressure through fluids to multiply force in car brakes and lifts.
Pressure differences above and below airplane wings create the lift necessary for flight.
The standard SI unit for pressure is the , which is defined as one Newton per square meter ( ). Other common units include:
