Physics Summary

  • Elasticity

    Elasticity is the property of a body, which enables the body to regain its original dimension when the deforming force acting on it is removed.

  • Hooke's Law

    Hooke's law states that within elastic limits the extension (or compression) is directly proportional to the force applied.

  • Pressure

    Pressure is force applied per unit area.

  • Atmospheric Pressure

    Atmospheric Pressure or barometric pressure is the force exerted by the air (its weight) on unit area.

  • Barometer

    Barometer is a device used to measure atmospheric pressure.

  • Manometer

    Manometer is one of the most accurate devices for measuring pressure, including atmospheric pressure in the lower ranges.

  • Pascal's Principle

    Pascal's Principle states that if the pressure at one point of a confined fluid is increased by an amount, the pressure increases by the same amount at all other parts throughout the fluid.
