As a foundational concept in physics, the force of gravity has been the subject of much study and debate over the centuries. This book, first published in 1785, offers a detailed analysis of the nature of centripetal and centrifugal forces, and their relationship to gravity. The author, a bishop and scholar of physics, provides a clear and compelling argument in favor of a precise mathematical formulation of these concepts. This is an important work for historians of science and anyone interested in the history of physics.
