In physics, gravity (from Latin gravitas 'weight'[1]), also known as gravitation or a gravitational interaction, [2] is a fundamental interaction, which may be described as the force that draws material objects towards each other.
The theory of gravity proposed by Newton stood for more than 200 years. Newton’s law of gravitation was one of the most successful theories ever produced. We still teach it in school, and most of us intuitively think of gravity as a force.
By his dynamical and gravitational theories, he explained Kepler’s laws and established the modern quantitative science of gravitation. Newton assumed the existence of an attractive force between all massive bodies, one that does not require bodily contact and that acts at a distance.
Newton’s law of universal gravitation describes gravity as a force between two masses, decreasing with distance. Einstein’s general theory of relativity redefines gravity as the curvature of spacetime caused by mass.
13.2: Newton's Law of Universal Gravitation All masses attract one another with a gravitational force proportional to their masses and inversely proportional to the square of the distance between them.
Gravity or gravitation is a natural phenomenon by which all things with energy are brought toward (or gravitate toward) one another, including stars, planets, galaxies, and even light and sub-atomic particles.
