hey.. what do mean mean by gravity..?

Question

i was told that that is a force which attracts everythin... but can somone tell me where does thsi force originate.. what is the power of this force.. n why do we experience it.. there r more q's attached to thsi but lets conquer these first.. cheers

Answer 1

Physicists are still wondering about that one! All we know is, gravity exists, and its power acts as if it is in the form of a field rather than in the form of particles or waves. If you've ever heard of Unified Field Theory, it's an as yet unknown theory that explains both the particle/wave mechanics of light and the field mechanics of gravity. For now, suffice to say that gravity most certainly works.

Answer 2

let's start at the beginning. The force of gravity performs work. In order for work to be performed there needs to be an energy source. It is impossible to perform work if there is no energy and, conversely, if there is energy, work is being performed in some manner. So, we need to find out what the energy source is that performs the origination of these waves.

There is a physics trilogy that explains this

E = mc2, m = E/c2, and c2 = E/m. The last is that of a field of physical time "c", or a field of gravity. The c2 value is a product of mass/energy. The values of energy and mass are not constant, but change according to relationship. c2 does not change. The reason for this is found in a short writing "What is a Graviton" at http://360.yahoo.com/noddarc.

The origin of this force lies with the heat energy within our planet. This is the "E" factor in c2 = E/m. Were our planet to be without any heat energy, then our planet would have no gravitational field. Were the heat energy contained within our planet to be increased, the gravitational field would also increase.

Another short writing at the above address is found at the end of "The Problem and Repair of Relativity". It is entitled "An Experiment You Can Help With". It is a short two page thesis on how to prove the existence of gravity by forming and collapsing a gravitational field.

Answer 3

This force originates from the distortion taking place in the space-time continuum due to the presence of the earth as it is explained in the General theory of Relativity of Einstein. As regarding the power of this force, it is the weakest among the four, viz., the gravity, the electromagnetic force, the weak nuclear force and the strong nuclear force. If strong nuclear force is taken to be of strength level 1 the gravity would be of strength level 10^(-40)!

Answer 4

The force of attraction between all masses in the universe; especially the attraction of the earth's mass for bodies near its surface; "the more remote the body the less the gravity"; "the gravitation between two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them"; "gravitation cannot be held responsible for people falling in love"--Albert Einstein

There are lot of forces which hold the Universe in its place. Gravitational force is one of them. In simple Terms :" A force of attraction between two bodies is Gravity"

Answer 5

In physics, gravitation or gravity is the tendency of objects with mass to accelerate toward each other. Gravitation is one of the four fundamental interactions in nature, the other three being the electromagnetic force, the weak nuclear force, and the strong nuclear force. Gravitation is the weakest of these interactions, but acts over great distances and is always attractive. In classical mechanics, gravitation arises out of the force of gravity (which is often used as a synonym for gravitation). In general relativity, gravitation arises out of spacetime being curved by the presence of mass, and is not a force. In quantum gravity theories, either the graviton is the postulated carrier of the gravitational force[1], or time-space itself is envisioned as discrete in nature, or both.

The gravitational attraction of the earth endows objects with weight and causes them to fall to the ground when dropped (the earth also moves toward the object, but only by an infinitesimal amount). Moreover, gravitation is the reason for the very existence of the earth, the sun, and other celestial bodies; without it matter would not have coalesced into these bodies and life as we know it would not exist. Gravitation is also responsible for keeping the earth and the other planets in their orbits around the sun, the moon in its orbit around the earth, for the formation of tides, and for various other natural phenomena that we observe.

Answer 6

Yes, it can be explained. Don't be fooled. The gravitational attraction of the earth endows objects with weight and causes them to fall to the ground when dropped. Every planetary body, including the Earth, is surrounded by its own gravitational field, which exerts an attractive force on any object that comes under its influence. This field is proportional to the body's mass and varies inversely with the square of distance from the body. The gravitational field is numerically equal to the acceleration of objects under its influence, and its value at the Earth's surface.
Newton’s law of gravitation states that: every particle in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
I'd suggest to research Newton and Einstein and get your own findings.

Answer 7

a really heavy body in a four dimensional space time wraps the space time around it...this wrapping results in gravity......thus the effect is proportional to the distance and the speed at which the body moves.........if the body is moving really fast or is really far away the effect is lesser as compared to if the body moves slowly and is nearer.......certain very heavy bodies wrap the curvature so much that even light gets bent around it.....this phenomenon can be observed during an eclipse,,,,,,for more refer relativity

Answer 8

1. Learn how to spell.
2. Study physics.

Answer 9

We can calculate the force of gravity but we have yet to discover what exactly causes it.

Answer 10

Get a good book (even a mediocre book) on undergraduate physics and read it.

Gravity is an 'intrinsic characteristic' of mass.
