Density (definition)
A
Mass per unit volume
2
Q
Pressure (definition)
A
Force per unit area
3
Q
Pressure in Fluids
A
Pressure increases with depth in a fluid because of the force exerted by the increased weight of the fluid above
4
Q
Archimedes Principle
A
The upthrust exerted on an object immersed in a fluid is equal to the weight of the fluid that the object displaces
5
Q
Sinking and Floating
A
Depends on the object’s density relative to the liquid
6
Q
The more of the object that is submerged in a fluid …
A
The greater the upthrust
