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.
Here’s what you’ll learn when you read this story: Einstein’s Theory of General Relativity, an immensely important update to Newton's Law of Universal Gravitation, is currently our best approximation ...
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.
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.
