What is the Gravitational Force ? <br /> <br />Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. <br /> <br />It is by far the weakest known force in nature and thus plays no role in determining the internal properties of everyday matter. <br /> <br />The works of Isaac Newton and Albert Einstein dominate the development of gravitational theory. <br /> <br />Isaac Newton’s classical theory of gravitational force held sway from his Principia , published in 1687, until Einstein’s work in the early 20th century. <br /> <br />Newton’s theory is sufficient even today for all but the most precise applications. Einstein’s theory of general relativity predicts only minute quantitative differences from the Newtonian theory except in a few special cases. <br /> <br />The major significance of Einstein’s theory is its radical conceptual departure from classical theory and its implications for further growth in physical thought. <br /> <br />Quantum mechanics - QM - also known as quantum physics or quantum theory), including quantum field theory, is a branch of physics which is the fundamental theory of nature at the smallest scales of energy levels of atoms and subatomic particles <br /> <br />Knowledge today
