Pressure

  • Is a Force exerted over a certain amount of area
    • The Force is mesured in Newtons
      • A Newton is the amount of force that is required to increase the speed of a one kilogram mass by one meter per second each second that the force is applied
    • The area is mesured in square meters
  • Mesurment
    • Barometer
      • A barometer mesures atmospheric pressure by the atmosphere pushing down on a liquid and causing it to rise up a vacumed column where the pressure can be mesured by little tick marks on the tube.
    • Manometer
      • Messures the gas pressure
  • Units
    • Pascal
