Gravity

Gravity is a field that is emitted from any object with a mass. Like all fields, in theory it will extend to infinity. However, also like all fields, its potency decreases at a rate of (1/r^2), that is if the field width increases by 2, it will be a quarter as effective as it was at the original distance. This is the inverse square law. So, in theory, we should be under the effect of the moons gravity, or even jupiter's! However, the force is so minuscule because of the vast distances, that we cannot feel it! So in answer to your question, yes, gravity does act from a distance. But it acts inversely square to the distance!

As we all know light is an electromagnetic wave, which is a wave composed of both a magnetic wave and an electric wave. It is also viewed as a particle called a photon. As a light beam approaches the sun it is attracted and repelled by the protons and electrons in the sun. The sum total effect of this, "Gravity" attracts and repels the sun at the same time. Coupled with the speed at which the photon is traveling the beam of light bends around the sun. As the light approaches, the photon is both repelled and attracted at the same time. Its velocity wants to carry it straight on, but as it gets closer to the sun the repulsion begins to effect the photons trajectory. Since the attractive force is greater this will lead to a shorter and sharper bend on the approaching side of the sun and a more gradual slope on the backside of the sun as the particle moves away from the sun. In reality, a constant stream of particles of photons are affected creating an unbroken beam of light that bends around the sun and reaches earth. This is how we are able to view light from a distant star that is hidden by the sun. The influence of matter in the sun on a beam of light as it approaches is what causes the electromagnetic wave to bend around the sun and reach earth.

at the farthest point from the center of gravity. On planet earth that would be the top of mt. Everest.

However there are anomalies in the gravitational field that lead to there being less gravity in certain places of the world. NASA and the German Aerospace Center have launched the Gravity Recovery and Climate Experiment(GRACE) to measure the anomalies around the world. Results can be seen here

"Surface gravity" is simply the strength of the gravitational field of a planet (or other object) at its surface. Often it is measured as the "acceleration due to gravity".

On Earth this is about 9.8 meters per second per second.

Gravity is not a form of energy itself, but it is a force that is responsible for attracting objects with mass towards each other. Energy can be associated with the movement or position of objects influenced by gravity, such as potential energy when an object is lifted against gravity or kinetic energy when it falls due to gravity.

Gravity is the force that pulls objects towards each other. In water, gravity affects the mass of the water and any objects in it, causing them to be pulled towards the center of the Earth. The force of gravity in water is the same as on land, approximately 9.81 m/s^2.

The force of gravity on one object due to another object depends on the mass of each object and their separation distance.

First of all, it depends on the escape velocity and the power measure of gravitational force. Second, isn't it pretty obvious to tell? Well, since you're asking, think of a ball of mass, supposedly earth or any other planet you know of, lets go with earth. If you were to jump, you fall back towards the ground, that's an effect of it, you falling back down is because the gravity is pushing you to standable landscape. if earth was bigger, with the same amount of gravitational force, the escape velocity would be less, meaning the power of how hard the gravitational force acted when you were on a smaller mass, would act less upon you, so that's how people can bounce around like movies on the moon.

The sun is much much more massive than Earth. Everything has gravity, even you (although very little). Everything pulls everything towards everything else by its own gravity. Planets and other celestial bodies are extremely massive, and the more massive something is the more it pulls on other objects with its gravity.

We measure it as a constant force pulling the plane toward the center of mass of the Earth, which usually coincides with the perpendicular to the ground. For simplicity, we call it "straight down".

Earth has a uniform gravitational field, which means that the force of gravity acting on an object near the Earth's surface is consistent throughout. This field attracts all objects towards the center of the Earth with an acceleration of approximately 9.81 m/s^2.

Gravity is the force behind precipitation in the water cycle. Rain, snow and other forms of falling water are carried to earth by gravity. There, the liquid water can wash materials away. Snow can accumulate and melt and do the same thing. Snow can also accumulate, freeze, and then become moving ice (a glacier). We know glaciers can move massive amounts of rock and other materials, and can shear off or grind materials because of their weight and/or the force of the moving ice mass.

We also know that gravity directly acts to "pull down" weakened geologic structures, like cliffs or even mountain sides. Loose rock or earth is dragged down from higher points all the time, and it might be one or two chunks of material, or a landslide. Even the great spires in places like Monument Valley will eventually succumb to gravity's pull.

It is expressed in m/s2.

The predicted gravity force carrier particle is called the "graviton." It is a hypothetical elementary particle that is expected to mediate the force of gravity in the framework of quantum field theory.

Velocity is defined as the rate at which an object changes its position in a specific direction. It is a vector quantity, meaning it has both magnitude (speed) and direction. Velocity is often measured in units such as meters per second (m/s) or kilometers per hour (km/h).

Gravity is related to mass, the more mass you have clumped together the stronger the gravity field of that clump of mass.

Thus if the clump loses some of its mass, the gravity field of that mass will decrease, and because it is possible to lose mass in this way (stellar explosions) it follows that it is indeed possible to lose mass and gravity.

it is blue lol=D

No... it's yellow of course

Contrary to popular misconception, and as much as we might wish that it were

otherwise, gravity is a queasy shade of brown, and when we see that and admit

it, we see the fruits of procrastination.

It didn't need to be so. But gravity, fancying itself the most important of all

forces even though nearly the weakest, put no effort into claiming its own color

when they were being handed out. It just sat back and let all the others queue

up and patiently wait their turn.

And finally, only then ... after magnetism, wavelength, density, acceleration,

amplitude, quantum number, reflection coefficient, buoyancy, conductivity,

linear momentum, luminosity, and abstinence had all been awarded their first

or second choices of color ... gravity ambled along, and was forced to accept

whatever was left.

There is no other way to describe it. It's a queasy shade of light brown.

I don't know.Do you know fat boy

The center of gravity plumbline method involves suspending an object to find its center of gravity by allowing it to hang freely and marking the line of plumb underneath it. The intersection of the plumb lines from two or more positions will determine the center of gravity. This method is commonly used in physics and engineering to locate the balance point of irregularly shaped objects.

Yes. The sun is attracted by the gravity of the planets just as the planets are attracted by the sun. Since the sun is more massive it does not move as much, bu the gravity of the orbiting planets does cause it to "wobble."

Th force would depend on the mass of the body it is interacting with

F=GMm/R2

G=gravitational constant

M-mass of sun

m=mass of object

R=radius of sun

An object that weighs 100 pounds on Earth would weigh about

2,790 pounds on the sun just before it melted and vaporized.

Commonly, there really is not a difference. However, if you are referring to Newtonian Law of Universal Gravitation and Einsteinian Relativity, then there is a difference. Both theories describe gravity. Universal Gravitation predicts an instantaneous force which attract objects together. Mass and distance of the objects are the two main components of Universal Gravitation. Einstein's Relativity explains Gravity as a distortion on the space-time fabric as a result of the presence of mass. These distortions cause what we experience as Gravity. Einstein's Gravity is not an instantaneous force because it travels at the speed of light.

The specific gravity of coal typically ranges from 1.1 to 1.5, depending on the type of coal and its composition. Specific gravity is a measure of density, comparing the weight of a substance to an equal volume of water.
