New cards

buoyancy

  • The ability to sink or float

  • 3 types

2
New cards

positive buoyancy

  • Object lighter than the fluid it displaces

3
New cards

negative buoyancy

  • Object is heavier than the fluid it displaces

4
New cards

neutral buoyancy

  • Object weighs the same as the fluid it displaces

5
New cards

archimedes principle

  • When an object is totally or partially immersed in water it experiences an upthrust equal to the weight of the fluid displaced

6
New cards

water density

  • Colder and saltier = denser

  • Density of fresh water

    • 1kg/L

  • Density of salt water

    • 1.03kg/L

7
New cards

calculating butyancy

Upthrust = object volume x density of the water

  • An object has a mass on land of 85 kg and a volume of 80 L in fresh water, calculate the objects’ upthrust.

Apparent mass = weight of object on land - upthrust

negative buoyancy = + apparent mass

Positive buoyancy = -apparent mass
