1.1. Objectives
The purpose of this lab was to understand the Archimedes’ Principle and to calculate the
density of unknown substances using both the Archimedes’ Principle and density definition.
1.2. Theoretical Background
When an object is submerged in fluid, it experiences both upward and downward forces
which are called gravitational force (or gravity) and buoyant force (or buoyancy). According to
the Archimedes’ Principle, the buoyant force on an object submerged in a fluid is equal to the
weight of the fluid displaced by the object. The following equation is used to determine the force
of buoyancy:
B = W L = m L g = ρ L V 0 g
Where B is the force of buoyancy, W L and m L are the weight and mass of displaced fluid,
ρ L is the density of the fluid, and V 0 is the volume of the fluid displaced by the submerged
object.
