what are the basic principles behind gravitational forces?

Answer 1

The energy per unit volume of a gravitational mass is the pressure holding the mass together. so if you multipy the gravitational pressure that hold the mass together by the area enveloping the gravitational mass you obtain the total force surounding the mass.
As Sherlock Holmes would say = "elementary...
Therefore from this analysis we see that The gravitational force is proportional to the curvature of the gravitational mass which in turns causes a curvature of the space gravity field.
And that is the whole principle of gravity.
It took me years to figure that one out.

Answer 2

Classically (which is the best place to start), the basic principle is the universal law of gravitation which states that all point particles are attracted to each other with a force proportional to the product of their masses, and inversely proportional to the square of the distance between them. The proportionality constant is determined empirically by measuring it for a special case (aka the Cavendish experiment).

General relativity provides a more general framework to describe gravity, but if you're going to be asking about such things as "forces" (a classical concept), you'd better focus on classical gravity for now.

Answer 3

Comparisons in Three Theories of Gravitation:
Newton, Nordström, Einstein...

Basic Principles Of Gravitational Forces:
Acceleration of static test particle
Extra-Coulomb tidal force
Radius of circular orbit
Gravitational red shift factor
Angle of light bending
Rate of precession of periastria
Time delay

Answer 4

Gravitational force is when an object is thrown into an orbital force it has inertia that pushes it forward and gravity to keep it from flying away in the end it results in a ring push a toy car off the table it falls right but when theres a greater force(inertia) it goes out further now pretend theres a string attached and the car would make a ring. so ya thats it.

Answer 5

The gravitainal force is the interaction between any two isolated bodies with mass. Any two objects with mass interact gravitationally. You and the computer screen, your mouse and the moon, ect.
In the General Theory of Relativity, gravity is the distortion of space and time caused by massive objects (objects with mass). Gravitational forces are a result of the reaction of objects with the distortion caused by a massive object. Even massless photons are affected with this distortion.
In Quantum Mechanics, it is postulated that gravitational interactions are an exchange of gravitons much the same way electromagnetic interactions are an exchange of photons.

Answer 6

utilizing the 0 regulation of thermodynamics: Qwater=-Qpan meaning that the water beneficial factors warmth capability, mutually as the pan loses it. That warmth isn't sufficient to evaporate the water (you prefer quite some warmth to evaporate water), so it basically motives flow contained in the water (with the aid of fact capability motives flow). once you shook the pan, you have been including added capability to the equipment; which became into sufficient to reason the droplets to evaporate. The water became into no longer sufficient to relax the pan with the aid of fact the capability the pan loses is very small in comparison with the preliminary finished capability of it, after heating it over the alcohol lamp.

Answer 7

The attraction between two bodies, M1 and M2is inversely proportional to the square of the distance between them

is proportional to M1.M2/r^2

Where r is the distance between them.

M1 and M2 are normally written with the little 1 and 2 as subscripts (at the bottom of the Ms) . The Ms are usually written m, but I wrote them big to try to balance the enormous subscripts.

Answer 8

Curvation of space, said Einstein, whatever that means.

Th

Answer 9

Centrifugal or centripetal forces.

Answer 10

I'm glad you asked me that question.

It's very simple: "Puh puh puh Push it... push it REAL good!"

I hope this helps.
