L’esperimento di Cavendish. ~ credit to Thegeocentricgnostic.com The Cavendish Experiment — Pseudoscience Nonsense Don’t be surprised if at some point an indoctrinated globehead pulls out the Cavendish experiment as proof of gravity and tries to shove it in your face. L' esperimento di Cavendish, eseguito negli anni 1797 - 1798 dallo scienziato britannico Henry Cavendish, è stato il primo esperimento volto a misurare la forza di gravità tra masse in laboratorio, ed il primo a consentire di ottenere valori accurati per la costante gravitazionale. There are plenty of hard numbers and lovely equations there, of a sort to satisfy and shock all but the most jaded. Although the balance has feet that can be adjusted to make it level, for best results the platform should be reasonably level as well. 0000069540 00000 n La formula per il calcolo della forza di gravità la dobbiamo a Newton, il quale affermo che tra due corpi tale forza è data dal rapporto tra il prodotto delle masse ed il quadrato della distanza delle stesse.La prima stima della costante gravitazionale invece la dobbiamo a Henry Cavendish, il quale ideò un esperimento che prende proprio il suo nome. The Cavendish experiment, performed in 1797–1798 by English scientist Henry Cavendish, was the first experiment to measure the force of gravity between masses in the laboratory and the first to yield accurate values for the gravitational constant.

Moreover, the first experiment to produce definitive values for the gravitational constant and the mass density of the Earth. Because of the unit conventions then in use, the gravitational constant does not appear explicitly in Cavendish's work.
