How is gravitational force formed ?

Answer 1

Gravitational force is formed due to Earth rotation and revolution and some part moon to act best role in earths gravity.

Best eg : If you fill one bottle of water dont close the lid just tie one thread to it and just rotate in a best to best speed ... u can find that water will not spill down... though the bottle lid is open...that mean some sort of power is generated.... u can use the same example for our earth.... but in Macro level...

Answer 2

Gravitational force if formed when gravitation forces converge on the epicenter of masses that exist in a space filled with other masses. The confluence of the masses causes a force between the two masses that is gravity. The gravitational force is proportional to the two masses and is affected by all the other masses. The sum of the masses adjusted for their individual mass and distance affect the force proportionally.

Answer 3

Everyone except sunil n (who is as wrong as anyone can be) have given some part of the correct answer.

The truth is, in physics we never 'know' anything, we can only theorize. Depending on your philosophical viewpoint, the Absolute Truth does not exist, is unreachable or at the very least is far from being reached in the near future. A physicist proposes a theory, which is a toolkit for translating physical situations into the language of mathematics, manipulating the mathematics to arrive at some result, and then translating the mathematical result back into physical predictions that can be verified by observations. From this viewpoint, theories are only more or less accurate at the predictions they make, but never Right or Wrong.

The most accurate theory of gravitation known to date is Albert Einsteine's General Theory of Relativity. In this theory, Einsteine says that there is in fact no gravitational force as such. The presence of mass and motion in space (modeled mathematically by the second-rank Stress-Energy tensor) causes space (and time) to 'curve'.

As Newton said, bodies travel along a straight line but since the background this straight line is drawn on is now bent, the body appears to bend also. This deviation from the flat spacetime straight line (called an inertial world line) creates the impression of a force. The body is still travelling undisturbed on a straight line, it's our viewpoint that has been bent. As the boy in Matrix said to Neo, "You can't bend the spoon, it's you yourself who bends."

All this is actually very mathematical can be very difficult to imagine, the rubber sheet experiment is only a crude approximation. Ultimatly there is only one way to understand physics, and that is through the mathematics. Like Euclid said, there is no royal road into physics. Popular physics books may be popular, but thye are not physics. If you are really interested in physics then read textbooks. A true understanding of gravitation would require that you have a working knowledge of manifold topology, differential geometry and tensor analysis.

It must be mentioned that GTR is not consistent with Quantum Mechanics and therefore must be revised. However no one has yet found a way to formulate a complete quantum mechanical theory of gravitation (gravitons are pure speculation). The one who suceeds is guaranteed eternal glory.

PS:- By the way perldude69, you are confusing the Cassimir effect with gravitation. The Cassimir effect is nowhere near as strong as gravitation.

Answer 4

A simple example would be to think about a thin sheet of rubber with a bowling ball sitting on it. Where the bowling ball (..mass) rests the sheet (..space) is distorted. That distortion represents the force of gravity caused by the presence of mass. In other words, gravity is actually a distortion in the "fabric" of space caused by the presence of mass. The greater the mass the stronger will be the gravitational force.

Einstein theorized all this long ago, and since then he's been proven absolutely correct by countless scientific experiments.

Answer 5

Gravity versus gravitation

In scientific terminlogy gravitation and gravity are distinct. Gravitation is the attractive influence that all objects exert on each other, while "gravity" specifically refers to a force which all massive objects are theorized to exert on each other to cause gravitation. Although these terms are used interchangeably in everyday use, in theories other than Newton's, gravitation is caused by factors other than gravity. For example, in general relativity, gravitation is due to spacetime curvatures which causes inertially moving object to tend to accelerate towards each other. Another (but discredited) example is Le Sage's theory of gravitation, in which massive objects are effectively pushed towards each other.

Answer 6

My theory, because no one knows.

Gravity is the result of zero point energy bombarding mass.

Picture a coke bottle sitting on a table. now throw a ping pong ball at the bottle. If you hit it, the bottle will shake, mostly in the direction opposite from where the ball came from.
Now throw 10,000 ping pong balls at the bottle from all directions. The bottle will shake in all directions, appearing to vibrate.
Now place two bottles on the same table. Repeat bombardment with 10,000 ping pong balls. The bottles vibrate, but also move towards each other.

The bottles shield each other from ping pong balls only in the direction facing each other.
Now imagine ping pong balls are really zero point energy waves, and the bottles are massive planets.

I hope this makes sense to you. Sometimes I have a hard time explaining my thoughts to others. I think my theory is better than most, for two reasons.
1. It explains gravity and gravitation using known phenomenon.
2. It is fun to imagine the ping pong ball fest!

Answer 7

gravitational force is formed when Mass comes into existance. It expands when Mass that has come into existance has started to collapse on itself. EM fields are created when Mass beings to expand and contract at the same time. Aka single mass generator or SMG theory.

Answer 8

There is no official answer to this question but I believe there may be an incredibly slight positive charge on the waves of space that can explain how the force of gravity works.

Answer 9

gravitational force is formed by earth's mass acting on our masses

Answer 10

seriously, no one knows. One may talk of gravitons and so on, but its just a different way of looking it... lets say its just there. mysterious.
