What it is
Instrument for measuring very small forces through the twist of a calibrated elastic fibre; developed by Charles-Augustin de Coulomb to measure the electric force between charges.
What it led to
- Coulomb's law of electric force (1785)
- Cavendish's measurement of the gravitational constant (1798)
- Methods for measuring weak forces in experimental physics
