buoyancyeffekt

The buoyancy effect, also known as Archimedes' principle, describes the upward force exerted by a fluid that opposes the weight of an immersed object. This principle states that the buoyant force on an object submerged in a fluid is equal to the weight of the fluid displaced by the object. When an object is placed in a fluid, it pushes aside a certain volume of that fluid. The weight of this displaced fluid creates an upward pressure that counteracts gravity's downward pull. If the buoyant force is greater than the object's weight, the object will float. If the buoyant force is less than the object's weight, the object will sink. If the buoyant force equals the object's weight, the object will remain suspended at its current depth. The density of the object relative to the density of the fluid is the key factor determining whether it floats or sinks. Denser objects tend to sink, while less dense objects tend to float. This effect is fundamental to understanding why ships float, why balloons rise, and many other phenomena involving objects in liquids and gases.
