  1. Fluid
    Any substance that can flow
  2. Density
    Mass per unit volume
  3. Archimedes priciple
    the size of upthrust in fluid is equal to the weight of the fluid an object has displaced
  4. Laminar flow
    • No abrupt change in velocity of flow  
    • velocity at a point is constant
    • flows in layers/flowlines/streamlines
    • layers do not mix/cross
    • layers are parallel
  5. Turbulent flow
    • Mixing of layers/flowlines/streamlines
    • contains eddies and vortices/whirlpools abrupt/random changes in speed or
    • direction
  6. Streamlines
    line of laminar flow
  7. Viscous drag?
    Frictional force in fluids
