The first method is by the measurement of force | Compare the values obtained for buoyant force |
---|---|
If the dirigible displaces exactly its weight, it hovers at a constant altitude | An object which tends to float requires a restraint force T in order to remain fully submerged |
It is the buoyant force that keeps ships afloat in water and hot air balloons floating in air.
13Compare this buoyant force to the weight of the wood cylinder | In this experiment, the buoyant force will be measured three ways and the results compared |
---|---|
This analogy is valid for variations in the size of the cube | Label this weight in air FA |
An object of any shape can be approximated as a group of cubes in contact with each other, and as the size of the cube is decreased, the precision of the approximation increases.
