##### 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.

True

Archimedes principle does not apply to partially submerged objects

False

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?

NO

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.

Displacement measures

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:
