When was the Cavendish experiment first performed?
Quick Answer
Henry Cavendish performed it in 1797–1798, making one of the first measurements of Earth's density.
The Full Story
Henry Cavendish carried out his famous torsion-balance experiment in 1797 and 1798. It is often described as the first precise measurement of the gravitational constant, although Cavendish himself framed it as a way to determine Earth's density. By measuring the tiny attraction between lead spheres, he showed that gravity could be measured in a laboratory. The experiment was a landmark in experimental physics.
