Density and Archimedes' Principle. Density plays a crucial role in Archimedes' principle. This is because the fluid, having a higher density, contains more mass and hence more weight in the same volume. The buoyant force, which equals the weight of the fluid displaced, is thus greater than the weight of the object.
The buoyant force on a submerged object is equal to the weight of the fluid displaced. This principle is useful for determining the volume and therefore the density of an irregularly shaped object by measuring its mass in air and its effective mass when submerged in water (density = 1 gram per cubic centimeter).
One may also ask, what are the principles of density? A materials density is defined as its mass per unit volume. Put another way, density is the ratio between mass and volume or mass per unit volume. The principle of density was discovered by the Greek scientist Archimedes, but it is easy to calculate if you know the formula and understand its related units.
In this manner, how does Archimedes Principle relate to buoyancy?
Archimedes Principle states that the buoyant force on a submerged object is equal to the weight of the fluid that is displaced by the object. Hot air balloons rise into the air because the density of the air (warmer air) inside the balloon is less dense than the air outside the balloon (cooler air).
How is density related to buoyancy?
Density is the ratio of mass to volume. Higher is the volume of the object, more is the amount of the liquid it displaces and higher will be the buoyancy force. Hence density reduces with increase in volume whereas buoyancy increases with volume, so they both are inversely proportional to each othere.
