Description from the creator

This video demonstrates how to determine the mass of the earth using some very simple equipment and a powerful mathematical expression. A century wide collaboration between Newton and Cavendish makes this possible. The video includes a discussion of Newton's universal law of gravitation and Cavendish's famous experiment that led to the determination of "G" the universal gravitational constant.
