  1. Newton's law of universal gravitation - Wikipedia

    • Newton's law of universal gravitation states 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. Separated objects attract and are attracted as if all their mass were concentrated at their centers. The publication of the la… 展开

    History

    Before Newton’s law of gravity, there were many theories explaining gravity. Philoshophers made observations about t… 展开

    Modern form

    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 the constant G is 6.67430(15)×10 … 展开

    Bodies with spatial extent

    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 th… 展开

    Vector form

    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 magnitude. In this formula, quantities in bold represent vectors.

    Gravity field

    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 gravitational acceleration at that point.
    It is a generalisat… 展开

    Limitations

    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 quantities and are both much less than one, w… 展开

    Extensions

    In recent years, quests for non-inverse square terms in the law of gravity have been carried out by neutron interferometry. 展开

     
  1. Newton’s law of gravitation is the magnitude of the attractive force F is equal to G multiplied by the product of the masses (m1 and m2) and divided by the square of the distance R : F = G(m1m2) R2.

    Newton’s theory says gravity affects everything in the universe. His law of universal gravitation shows how. It’s F = GmM/r², where F is the force, m and M are masses, and r is the distance.
