Density (definition)
Mass per unit volume
Pressure (definition)
Force per unit area
Pressure in Fluids
Pressure increases with depth in a fluid because of the force exerted by the increased weight of the fluid above
Archimedes Principle
The upthrust exerted on an object immersed in a fluid is equal to the weight of the fluid that the object displaces
Sinking and Floating
Depends on the object’s density relative to the liquid
The more of the object that is submerged in a fluid …
The greater the upthrust
