Editing Archimedes' principle (section)

==Explanation==

In ''[[On Floating Bodies]]'', Archimedes suggested that (c. 246 BC):
{{Quotation|Any object, totally  or partially immersed in a fluid or liquid, is buoyed up by a force equal to the weight of the fluid displaced by the object.}}
Archimedes' principle allows the buoyancy of any floating object partially or fully immersed in a fluid to be calculated. The downward force on the object is simply its weight. The upward, or buoyant, force on the object is that stated by Archimedes' principle above. Thus, the net force on the object is the difference between the magnitudes of the buoyant force and its weight. If this net force is positive, the object rises; if negative, the object sinks; and if zero, the object is neutrally buoyant—that is, it remains in place without either rising or sinking. In simple words, Archimedes' principle states that, when a body is partially or completely immersed in a fluid, it experiences an apparent loss in weight that is equal to the weight of the fluid displaced by the immersed part of the body(s).
