The Cavendish Experiment was conducted by scientist Henry Cavendish in 1798 to measure the force of gravitational attraction between masses. Using a simple apparatus, he suspended a horizontal bar with two small lead spheres at each end. When larger lead spheres were placed nearby, the bar twisted slightly, allowing Cavendish to calculate the gravitational force between the objects. This groundbreaking experiment not only provided the first accurate measurement of the gravitational constant but also helped determine the mass of the Earth. The results laid the foundation for modern physics and our understanding of gravity, influencing future research in the field of astrophysics.
