Buoyancy: Archimedes Principle ... There are two types of flying machines that allow for lift to overcome gravity. The first type, called the aerodynamic machines such as helicopters ... Archimedes Principle states that the buoyant force on a submerged object is equal to the weight of the fluid that is displaced by the object.

Archimedes' principle is the law of buoyancy. It states that "any body partially or completely submerged in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the body." The weight of an object acts down...

Archimedes' principle, principle that states that a body immersed in a fluid is buoyed up by a force equal to the weight of the displaced fluid. The principle applies to both floating and submerged bodies and to all fluids, i.e., liquids and gases.

An object is buoyed up with a force equal to the weight of the liquid it displaces. ... This is known as Archimedes' Principle. As an example, suppose you pushed an empty (and sealed) one-liter milk carton under the water in your bath tub.

Buoyancy - Wikipedia, the free encyclopedia
In physics, buoyancy (pronounced /ˈbɔɪ.ənsi/ ) is the upward force that keeps things afloat. The net upward buoyancy force is equal to the magnitude of the weight of fluid displaced by the bod...

Archimedes' Principle is that an object totally or partially immersed in a fluid (liquid or gas) is buoyed (lifted) up by a force equal to the weight of the fluid that is displaced.

In the first century BC the Roman architect Vitruvius related a story of how Archimedes uncovered a fraud in the manufacture of a golden crown commissioned by Hiero II, the king of Syracuse.

Since the "water ball" at left is exactly supported by the difference in pressure and the solid object at right experiences exactly the same pressure environment, it follows that the buoyant force on the solid object is equal to the weight of the water displaced (Archimedes' principle).
