Learn about the concept and properties of gravitational field, a vector field that describes the influence of a body on its surroundings. Compare the classical and general relativistic approaches to gravitational field and their applications.
Learn about Newton's law of gravitation, gravitational field, gravitational potential and related concepts. Explore interactive visualizations and examples of gravitational fields and forces.
Learn about the concept of gravitational field and how to calculate its magnitude and direction using Newton's law of gravitation. Explore the effects of relativity, flux, and multiple masses on the gravitational field.
In this section, we study the nature of the gravitational force for objects as small as ourselves and for systems as massive as entire galaxies. We show how the gravitational force affects objects on Earth and the motion of the Universe itself.
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.
14 mar 2021 · Newton’s Law of Gravitation states that each mass particle attracts every other particle in the universe with a force that varies directly as the product of the mass and inversely as the square of the distance between them. That is, the force on a gravitational point mass mG produced by a mass MG. Fm = − GmGMG r2 ˆr.
According to the general theory of relativity, a gravitational field bends light. What does this have to do with time and space? Gravity has no effect on the space-time continuum, and gravity only affects the motion of light.
