Archimedes’ principle states that a body fully or partially submerged in a fluid experiences a buoyancy force equal in
magnitude to the weight of the fluid displaced. This can be written as
| where FB is the buoyancy force, ρfl is the density of the fluid g is the acceleration due to gravity and Vs is the volume submerged in the fluid |
 Balance with Metal attached |
 Balance with Wood and Sinker attached |
This experiment demonstrats the boyancy forces on a piece of metal, and a block of wood with a sinker attached
Experimental Apparatus: to measure the weight of your object,
click an add mass button to balance the scale to determine the apparent weight of the object.
| Object | Apparent Mass | Mass in Air | Calculation | Result | |
| Metal | 0.603 N |  | kg m3 | ||
Sinker Sinker + Wood | 0.619 N |  | kg m3 |
