Objective:
To measure the buoyant force of different objects using experiment on Archimedes principle.
Hypothesis:
If the weight of the water displaced is less than the weight of the object, the objects will sink. Otherwise the object will float, with the weight of the water-displaced equal to the weight of the object. The buoyancy force on the submerged object is equal to the weight of the liquid displaced by the object.

Archimedes' principle indicates that the upward …show more content…
Decant the strong (saturated) salty water and store for further use. A spring balance is hanged in an iron stand using a clamp the least count is noted. One of the solid blocks is taken and weighed by hanging it on the hook of the spring balance using a thread; the weight of solid in air is found and noted. Two beakers, which measure 250ml each are taken and marked as A, and B. They are weighed separately and the mass is noted, then an overflow can filled with water till the brim is placed below beaker A to the displaced water, then a metallic block attached to a spring balance is lowered into a overflow can filled with water, the loss of weight of the metallic block is noted after it is completely immersed in water and the beaker which contains the displaced water is weighed to find the mass of water displaced and then subtracted from the initial …show more content…
Sources of Error:
The possible sources for error in the this experiment include, inaccurate senor readings, remaining water residue on the metal blocks, an added volume of displaced water due to the hook on the blocks and swing on hooks after they are in place. The calculated densities are significantly larger than water (1 g/cm3). This is expected because metals are typically denser than water and therefore, are obviously not able to float. The apparent weight indicated by the scale will be smaller because there is still a small buoyant force pushing up on the metal cylinder.
Applications:
Applications of Archimedes principle in everyday life
Ships
Ships would sink to a certain level until its weight is equal to the buoyant force.
Submarines
Submarines can submerge to a depth where its buoyant force is equal to its
