A
Apparent weightmeasured weight of an object when buoyant force acts on it | |
Archimedes' Principlebuoyant force equals the weight of displaced fluid | |
Average densitytotal mass divided by total volume of an object or system | |
B
Ballastmaterial or water used to control mass, stability, or buoyancy | |
Ballast tanktank used to adjust the mass and buoyancy of a submarine | |
Buoyancy control device(BCD) – adjustable flotation equipment commonly used by scuba divers | |
Buoyant forceupward force exerted by a fluid on an immersed object | |
D
Displaced fluidfluid pushed aside by an immersed object | |
Displacementmovement of fluid caused when an object occupies space within it | |
Draftvertical distance between the waterline and the lowest part of a vessel's hull | |
