- How did mankind first determine the mass of the Earth? | Science Guys . . .
The first person credited with "weighing" the Earth was Henry Cavendish (1731-1810 ) But we must first mention one of the greatest physicists who ever lived - Isaac Newton (1642-1727) Newton’s Law of Universal Gravitation states that any two masses are attracted to one another
- Cavendish experiment - Wikipedia
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 [1] and the first to yield accurate values for the gravitational constant
- June 1798: Cavendish weighs the world - American Physical Society
Among his many experiments, he is most famous for what is now called the Cavendish experiment, which he used to determine the density of Earth Newton had published his law of gravitation in 1687, but he hadn’t made any attempt to determine the constant G or the mass of Earth
- By whom and how was the mass of the earth discovered?
In 1798 Henry Cavendish was the first person to measure the mass of earth and for this purpose he calculated the value of constant G (gravitational constant) because the value of g and the
