    Pressure

    The force applied on a fluid over a specific area.

    Compressibility

    How easily a fluid can be compressed; gases compress easily and liquids do not.

    Force

    A push or pull that causes movement.

    System

    A group of parts that work together to perform a function.

    Compress

    To squeeze something into a smaller space.

    Hydraulic System

    A system that uses liquids under pressure to transmit force.

    Pneumatic System

    A system that uses gases under pressure to transmit force.

    Pascal's Law

    Pressure applied to a confined fluid is transmitted equally in all directions.

    Pressure Formula (P = F ÷ A)

    Pressure equals force divided by area.

    Force Formula (F = P × A)

    Force equals pressure multiplied by area.

    Area Formula (A = F ÷ P)

    Area equals force divided by pressure.

    Unit of Pressure

    Pascal (Pa).

    Unit of Force

    Newton (N).

    Blaise Pascal

    Scientist (1623-1663) who discovered Pascal's Law about fluid pressure.

    Isaac Newton

    Physicist (1643-1727) who created the three laws of motion and defined force.

    Newton's Second Law (F = m × a)

    Force equals mass multiplied by acceleration.

    Mass

    The amount of matter in an object, measured in kilograms (kg).

    Acceleration

    The rate of change of velocity, measured in meters per second squared (m/s²).

    Force-Pressure Relationship

    Force and pressure are directly proportional when area stays constant.
