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

2

For a floating object how does its density relate to the density of the fluid?

pfluid > pobject

3

Any liquid or gas can be considered a fluid.

True

4

Archimedes principle does not apply to partially submerged objects

False

5

When an object is being submerged into a fluid the buoyant force acting on it does what?

The buoyant force increases with depth

6

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

7

Direct measurement is the

difference between the actual weight of the object (Wo) and its apparent weight (Wa) when fully submerged.

8

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:
