مبدأ ارخميدس. أرخميدس

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

ما هو مبدأ أرخميدس ؟ وما هي قصة اكتشافه ؟

It is the buoyant force that keeps ships afloat in water and hot air balloons floating in air.

Please note that for the third method, the volumes of interest are different for objects that float and objects that sink

Calculate the density of the wood
Compare 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

قوانين الطفو لأرخميدس

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.

The second method is the displaced volume method

Thus, only in the special case of floating does the buoyant force acting on an object equal the objects weight
