[[Fluids]]

# Summary
|
|
* Fluid particles obey Newton laws.
|
|
* Buoyant force is a net upwards force on an object in a fluid, caused by pressure and increases with depth.
|
|
* Buoyant force equals weight of fluid displaced: $F_b=pVg$ where p is fluid density and V is displaced volume.
|
|
* For a floating object, buoyant force equals the object's weight: $V_{submerged}/V=p_{object}/P_{fluid}$
|
|
* Object floats when density is less than fluids and sinks when it's greater. |
