• KeysToMaths: Density, Buoyancy and Apparent Weight
The ratio, (density of a floating object) : (density of liquid) equals the fraction of the floating object by volume that is immersed in the liquid. Newton's Second and Third laws are used to explain how a spring balance works. The (true) weight W of an object is the force of gravity on the object and thus is constant. The apparent weight (reading on balance) of an object immersed in a liquid is W - B where B is the buoyancy of the object.

• KeysToMaths: Law of Flotation
The Law of Flotation says that for a floating object, the weight of the object equals the weight of the liquid displaced by the object. We prove this by using Archimedes' Principle with Newton's Second law applied to an object in equilibrium (floating).
