Cavendish

Cavendish refers to an experiment conducted by scientist Henry Cavendish in the late 18th century, designed to measure the Earth's density and observe the force between masses. He used a torsion balance, a device with a rod and small lead spheres, suspended so it could rotate slightly. By placing larger spheres nearby, he observed tiny twists in the wire caused by gravitational attraction. Analyzing these twists allowed him to calculate the Earth's mass and density. This experiment was fundamental in confirming Newton’s law of universal gravitation and deepened our understanding of gravitational forces.
