This process is experimental and the keywords may be updated as the learning algorithm improves. These keywords were added by machine and not by the authors. According to that, buoyancy is depending on the density of the body itself and on the density of the liquid in which the body is in (◘ Fig. This phenomenon can as well be described with the downforce F G and the lifting force F A. If it is higher in comparison to the fluid, it sinks. If the density of the object ( ρO) is lower than that of the fluid ( ρFl), it has buoyancy and floats. This property is determined by density ( ρ) of an object. An object placed in the water begins either to swim or to sink. Archimedes found out that the buoyancy, or the reduction of the downforce in a liquid, equals the weight of the displaced fluid. Since the lump of gold in the water was heavier than the crown despite having the same weight above water, he realised that the crown may not consist of pure gold. He compared the crown and an equally heavy lump of gold on a scale immersed in the water. A body is experiencing a reduction in the downforce (G) in fluid. While he did not use Archimedes principle in the widespread tale and used displaced water only for measuring the volume of the crown, there is an alternative approach using the principle: Balance the crown and pure gold on a scale. calculated pi to the most precise value known. invented one of the most fundamental concepts of physics the center of gravity. discovered the laws of levers and pulleys, which allow us to move heavy objects using small forces. He previously noticed how his body extruded water out of a tub and simultaneously seemed to become “lighter”. Archimedes reportedly exclaimed 'Eureka' after he realized how to detect whether a crown is made of impure gold. In the 3rd Century BC, Archimedes: invented the sciences of mechanics and hydrostatics. Archimedes looked for a solution on how he could test the crown of King Hiero of Syracuse on its content of gold.
