    Pressure and Force

    • An increase in the area over which a force is distributed results in a decrease in pressure, as the force is spread out over a larger area.
    • Pressure is directly proportional to force, but inversely proportional to the area over which the force is applied.
    • The relationship between force and pressure can be mathematically expressed as pressure = force / area.

    Units of Pressure

    • The SI unit of pressure is the Pascal (Pa), which is defined as one Newton per square meter (N/m²).
