Buoyancy tersely: Buoyancy = weight of displaced fluid. Archimedes' principle does not consider the surface tension (capillarity) acting on the body, but this additional force modifies only the amount of fluid displaced and the spatial distribution of the displacement, so the principle that "Buoyancy = weight of displaced fluid" remains valid. The weight of the displaced fluid is directly proportional to the volume of the displaced fluid (if the surrounding fluid is of uniform density). In simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or
Buoyancy aid recyclable materials. Older designs used vertically aligned ribs of foam all around the body, but more modern designs typically feature front and rear slabs of foam buoyancy, with the sides left clear to allow unrestricted rotation and arm movement. Most buoyancy aids are one of three basic designs: All buoyancy aids include some form of strap for tightening the buoyancy aid, preventing it from coming off in the water. Many white water designs feature multiple straps on the shoulders and waist to ensure the buoyancy aid can not be swept off in fast water. They may also include pockets for
