Fluid Pressure and Buoyancy
Learn why objects float or sink in liquids and gases.
What you will learn
- Pressure in a fluid increases with depth due to the weight of the column above.
- Archimedes' principle states that buoyant force equals the weight of displaced fluid.
- An object floats if its density is less than the fluid it displaces.
