A gravitational field is used to explain gravitational phenomena, such as the gravitational force field exerted on another massive body. It has dimension of acceleration (L/T 2 ) and it is measured in units of newtons per kilogram (N/kg) or, equivalently, in meters per second squared (m/s 2 ).
The gravitational field is the gravitational force per unit mass that would be exerted on a small mass at that point. It is a vector field , and points in the direction of the force that the mass would feel.
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.
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.
10 maj 2021 · Revision notes on 13.1.1 Gravitational Fields for the CIE A Level Physics syllabus, written by the Physics experts at Save My Exams.
Gravitation is a great starting point for the subject of fields, introducing and developing concepts that are found in all field physics (such as field strength and potential), and it also gives an opportunity for revising Circular Motion and Energy.
In this post, we’re going to explore the characteristics of gravitational fields and properties such as gravitational force, gravitational field strength and gravitational potential energy. Let’s begin!
