Force newtonienne
For points inside a spherically symmetric distribution of matter, Newton's shell theorem can be used to find the gravitational force. The theorem tells us how different parts of the mass distribution affect the gravitational force measured at a point located a distance r 0 from the center of the mass distribution: See more Newton's law of universal gravitation is usually stated as 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 … See more In modern language, the law states the following: Assuming SI units, F is measured in newtons (N), m1 and m2 in kilograms (kg), r in meters (m), and … See more Newton's law of universal gravitation can be written as a vector equation to account for the direction of the gravitational force as well as its … See more Newton's description of gravity is sufficiently accurate for many practical purposes and is therefore widely used. Deviations from it are small when the dimensionless … See more Early history In 1604, Galileo Galilei correctly hypothesized that the distance of a falling object is … See more If the bodies in question have spatial extent (as opposed to being point masses), then the gravitational force between them is calculated by summing the contributions of the notional point masses that constitute the bodies. In the limit, as the … See more The gravitational field is a vector field that describes the gravitational force that would be applied on an object in any given point in space, per unit mass. It is actually equal to the See more WebOct 23, 2007 · Considering a small test body and an obstacle, a shield in the spherically symmetric electromagnetic radiation field of an absolute black-body enclosure, the radiation having a continuous spectrum, 0≤ν≤∞, the author demonstrates that between the two bodies a Newtonian force has to appear, as an effect of damping a symmetric, homogeneous, …
