This principle underpins lactometers and hydrometers, which are used to determine the density of liquids and measure the purity of a sample of milk. In the previous classes, you have studied gravitation multiple times. Common Hydrometer Because the liquid or water exerts an upward force on the items immersed in it, they appear to be lighter in water or any other liquid. The universal law of gravitation is a mathematical relationship that Sir Isaac Newton proposed to measure the gravitational force. During a free fall, both go downhill with the same acceleration, which is equal to gravity's acceleration. Meta-centre and Equilibrium of Floating Bodies This theorem is an important limiting result regarding the power of formal axiomatics, but has also been of immense importance in other areas, such as the theory of computability.
