# Coulomb Sentence Examples

**Coulomb**is distinguished in the history alike of mechanics and of electricity and magnetism.- The practical unit of quantity of electricity, the
**coulomb**, is named after him. **Coulomb**, who by using very long and thin magnets, so arranged that the action of their distant poles was negligible, succeeded in establishing the law, which has since been confirmed by more accurate methods, that the force of attraction or repulsion exerted between two magnetic poles varies inversely as the square of the distance between them.- No material advance upon the knowledge recorded in Gilbert's book was made until the establishment by
**Coulomb**in 1785 of the law of magnetic action. **Coulomb**, 2 however, by using long and thin steel rods, symmetrically magnetized, and so arranged that disturbing influences became negligibly small, was enabled to deduce from his experiments with reasonable certainty the law that the force of attraction or repulsion between two poles varies inversely as the square of the distance between them.- The accuracy of this law was in 1832 confirmed by Gauss, 3 who employed an indirect but more perfect method than that of
**Coulomb**, and also, as Maxwell remarks, 1 The quotations are from the translation published by the Gilbert Club, London, 1900. - The friction of water, investigated for slow speeds by
**Coulomb**, was measured for higher speeds by William Froude (1810-1879), whose work is of great value in the theory of ship resistance (Brit. - CHARLES AUGUSTIN
**COULOMB**(1736-1806), French natural philosopher, was born at Angouleme on the 14th of June 1736. **Coulomb**proved that this mechanical force varies inversely as the square of the distance between the centres of the spheres.**Coulomb**proved experimentally that the electric force just outside a conductor at any point is proportional to the electric density at that point.- Meters intended to measure electric quantity are called
**coulomb**meters and also ampere-hour meters; they are employed for the measurement of public electric supply on the assumption that the electromotive force or pressure is constant. - Experiments on friction have been made by
**Coulomb**, Samuel Vince, John Rennie, James Wood, D. - The following empirical formulae for the stiffness of hempen ropes have been deduced by Mono from the experiments of
**Coulomb**: Let F be the stiffness in pounds avoirdupois; d the diameter of the rope In inches, fl = 48d2 for white ropes and 35d2 for tarred ropes; r the effectire radius of the pulley in inches; T the tension in pounds. **Coulomb**(1736-1806), who in France addressed himself to the same kind of exact quantitative work as Cavendish in England.**Coulomb**has made his name for ever famous by his invention and application of his torsion balance to the experimental verification of the fundamental law of electric attraction, in which, however, he was anticipated by Cavendish, namely, that the force of attraction between two small electrified spherical bodies varies as the product of their charges and inversely as the square of the distance of their centres.- Adopting the hypothesis of two fluids,
**Coulomb**investigated experimentally and theoretically the distribution of electricity on the surface of bodies by means of his proof plane. **Coulomb**experimentally proved that the law of attraction and repulsion of simple electrified bodies was that the force between them varied inversely as the square of the distance and thus gave mathematical definiteness to the two-fluid hypothesis.**Coulomb**(1781), and afterwards confirmed by A.**Coulomb**pointed out long ago that the resistance of a body to be set in motion was in many cases much greater than the resistance which it offered to continued motion; and since his time writers have always distinguished the "friction of rest," or static friction, from the "friction of motion," or kinetic friction.**Coulomb**, Mem.
