Chapter Objectives:

  • Describe what determines the pressure of a liquid at any point.
  • Explain what causes a buoyant force on an immersed or submerged object.
  • Relate the buoyant force on an immersed or submerged object to the weight of the fluid it displaces.
  • Describe what determines whether an object will sink or float in a fluid.
  • Given the weight of a floating object, determine the weight of fluid it displaces.
  • Describe how Pascal's principle can be applied to increase the force of a fluid on a surface.
