I have the same kind of trouble sometimes. Good luck with working this issue out. I so know what you mean...
Archimedes, indeed it's law of buoyancy.
The word pertaining to floatation is spelled buoyance(also buoyancy).
The principle of buoyancy.
floataiton is really just bouyancy. the gravity pushes down and the buoyancy pushes up! at least i think it works that way.
In an egg floatation project, the constant factor used is the density of the liquid in which the egg is placed. By changing the density of the liquid (e.g., by adding salt to water), you can observe how it affects the buoyancy of the egg and whether it sinks or floats.
Ships, boats etc.
The law of floatation states that a floating object displaces its weight of fluid equal to the weight of the object itself. If the weight of the object is less than the weight of the fluid it displaces, it will float; if it is greater, it will sink. This principle is why ships and other objects can float on water.
I have no idea
some applications are floatings of ships, submarines, icebergs,man,fish and rising of balloons
For one, buoyancy has to do with how dense something is, that's why ships are hollow.
Model ships are made to test buoyancy and to scale out the ship. If the model doesn't work, the ship might not work.
Buoyancy: The ability to displace water and remain afloat. Emergency (or reserve) Buoyancy in small boats is provided by chambers filled with foam or just sealed so water cant get in. Thus the boat can't sink preventing disaster For larger ships the same effect is achieved by separating the sections of the vessel into water tight chambers. Normally the goal is to divide large ships so that damage that allows water into two or even three chambers does not result in the loss of the ship.
