Physic lab Archimedes’ Principle
Archimedes' Principle says that in the case of an object completely submerged in a fluid, solely due to its own weight, the buoyant force is:
The buoyant force is equal to the weight of the fluid displaced
For a floating object how does its density relate to the density of the fluid?
pfluid > pobject
Any liquid or gas can be considered a fluid.
Archimedes principle does not apply to partially submerged objects
When an object is being submerged into a fluid the buoyant force acting on it does what?
The buoyant force increases with depth
Do the densities of the objects effect the value of buoyant?
Buoyancy is a function of the density of the FLUID and the WEIGHT of the object
Direct measurement is the
difference between the actual weight of the object (Wo) and its apparent weight (Wa) when fully submerged.
the fact that the volume of fluid displaced (Vf) is equal to the volume of the object (Vo) that is submerged. Recall that density (ρ) = m/V, such that:
