The PASCO scientific AP-8215 Gravitational Torsion Balance reprises one of the great experiments in the history of physics— the measurement of the gravitational constant, as performed by Henry Cavendish … The PASCO scientific AP-8215A Gravitational Torsion Balance ... Cavendish's experiment was so well constructed that it was a hun-dred years before more accurate measurements were made. Although the balance has feet that can be adjusted to make it level, for best results the platform should be reasonably level as well.

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.
