1.8 Pressure

• Pressure


  Force per unit area

  
• Pressure


  • force (N)
  • area (m2)
  • unit: pascal (Pa)

  
• Pressure in liquids


  • pressure (Pa)
  • density (kg/m3)
  • gravitational acceleration (9.8 m/s2)
  • depth (m)

  
• Pressure increases


  • when you go deeper
  • with a denser liquid
• 9.8 N/kg
