Universal GravitationNewton was confident that the same force of attraction would act between any two objects, anywhere in the universe. He proposed his law of universal gravitation, which states that objects attract other objects with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them.

Cavendish’s ExperimentIn 1798, Englishman Henry Cavendish used equipment similar to the apparatus shown below to measure the gravitational force between two objects.

Gravitational AttractionA 50 kg person and a 70 kg person are sitting on a bench close to each other.  Estimate the magnitude of the gravitational force each exerts on the other. PRACTICE
