Key Concepts

Buoyancy

The upward force exerted by a fluid that opposes the weight of an object submerged in it.

Metacentric Height

A measure of the initial stability of a floating body. It is defined as the distance between the center of gravity and the metacenter.

Archimedes' Principle

A principle stating that a body immersed in a fluid experiences an upward buoyant force equal to the weight of the fluid displaced by that body.

Pressure Gradient

The rate of change of pressure in a fluid with respect to distance, often causing movement within the fluid.
