Archimedes' principle is named after Archimedes of Syracusethe first to discover this law.

Buoyancy is a force exerted by a liquid or gas that opposes an object's weight. Buoyancy can also be stated as the weight of displaced fluid. Pressure in a fluid increases with depth as a result of the weight of the overlying fluid see hydrostatic pressure.

Thus an object submerged in a fluid, experiences greater pressure at the bottom of the fluid than at the top. This difference in pressure results in a net force that tends to accelerate an object upwards. The magnitude of that force is proportional to the difference in the pressure between the top and the bottom of the column, and is also equivalent to the weight of the fluid that would otherwise occupy the column, i.

It is for that reason that an object whose density is greater than that of the fluid that it is submerged in will sink. Archimedes' principle allows Archimedes principle the experimental determination of density by providing an easy and accurate method for determining the volume of an irregularly shaped object.

Archimedes' principle is named after Archimedes of Syracuse, who first discovered this law in B. Archimedes' principle may be stated thus in terms of forces: Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object.

He had traveled to Alexandria, Egypt, a place of great learning, where he studied the works of some other mathematicians, like Euclid and Conon. Archimedes helped his friend King Hiero II by creating machines for the king's army.

The pulley was one of these inventions, but Archimedes thought the study of mathematics was the most important thing he could do. Archimedes wrote some books about Mathematics, including On Floating Bodies.

Archimedes died during the Siege of Syracuse when he was killed by a Roman soldier despite orders that he should not be harmed For objects, floating and sunken, and in gases as well as liquids, Archimedes' principle may be stated in terms of forces: Archimedes' principle indicates that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces.

Notice that the acting forces increase with the depth of the fluid. The resultant of all forces upward is called buoyancy and is equal to the weight of the displaced fluid. Archimedes principle allows the buoyancy of an object partially or wholly immersed in a liquid to be calculated.

The downward force on the object is simply its weight. The upward, or buoyant, force on the object is that stated by Archimedes' principle, above. Thus the net upward force on the object is the difference between the buoyant force and its weight.To connect the words of Archimedesâ€™ Principle to the actual behavior of submerged objects.

To examine the cause of buoyancy, that is the variation of pressure with depth in a fluid. To use Archimedesâ€™ Principle to determine the density of an unknown material.

Archimedesâ€™ Principle (which is derivable from mechanics) states that a body immersed in a fluid is buoyed up by a force equal to the weight of the displaced fluid.

Consider now a . Archimedes. Archimedes of Syracuse (c BC - c. BC) was an ancient Greek mathematician, physicist and engineer.

Although little is known about his life, he is regarded as one of the most important scientists in classical antiquity. Archimedes principle can be stated as (i) a body immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced and (ii) a floating body displaces its .

Archimedes's principle indicates that the upward buoyant force that is exertit on a bouk immersed in a fluid, whether fully or pairtially submerged, is equal tae the wicht o the fluid that the body displaces an it acts in the upward direction at the centre o mass o the displaced fluid.

Archimedes is considered by manyas the greatest scientist of the ancient world. Born in Syracuse, Greece, in BC, Archimedes was equally adept at Mathematics, Physics and Astronomy, besides being a prolific inventor and engineer.
