Classical mechanics. Newton's law of universal gravitation says that every particle attracts every other particle in the universe with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Jan 6, 2022 · What is gravity? Gravity is a pulling force (always a force of attraction) between every object in the universe (every bit of matter, everything that has some mass) and every other object. It's a bit like an invisible magnetic pull, but there's no magnetism involved.
Gravity is just geometry, the result of the curvature by massive objects of the space and time around them. The strength of the gravitational “ field ” at any point in space or time is just the...
