How long from the surface of earth does the gravitation force work?

There's no limit. The simple formula for the gravitational force doesn't say "This formula
only works for distances less than (---)". If you know the mass of each object, you can
calculate the gravitational force between them when they're any distance apart, even
in different galaxies. Of course, the force continues to get smaller and smaller as the
distance increases, but it's still there and it never shuts off, no matter how big the
distance gets.

Which of the four fundamental forces of nature is responsible for keeping the earth in orbit about the sun?
electromagnetic - long range, either attractive or repulsive, moderateweak nuclear - short range, either attractive or repulsive, weakstrong nuclear - very short range, either attractive or repulsive, very stronggravity - long range, always attractive, very weak
Do force exist to object at rest?
There CAN be, as long as the force is being counterd by an equal and opposite force.
How long was the surface of the earth molten?
The earth was in molten state for approximately 0.8-1 billion years.
Does earth have rilles?
Yes, both the earth and moon have rilles. A rille can be defined as a small brook (as on Earth) and as a long narrow straight valley on the moon's surface.
The period of time in which a long term reduction of temperature in the earth's surface occured?
Ice Age.
What is the gravitational force between 1 kg of marshmallow and Earth?
9.8 newtons (2.204 pounds), as long as they're reasonably near the earth's surface

How long has the surface on earth been changing?
for as long as it has had continents
Would the moon orbit around the earth regardless of whether the sun is present?
Yes. As long as no other gravitational bodies are close enough to pull it out of Earth's gravitation.
Why don't falling objects have constant velocity?
By now, we should all be comfortable with the fact that as long as there's a force acting on an object, the object continues to accelerate, that is, to move, in the direction of the force, with increasing speed. Any two objects have a pair of equal forces acting on them ... the forces of universal gravitation, which attracts every object to every other object. So every two objects that are free to move must accelerate toward each other. When I'm up in the air above the earth's surface, I'm attracted toward the earth with a force of 185 pounds, and the earth is attracted toward me with a force of 185 pounds. Both I and the earth are accelerated by the forces on us. My acceleration toward the earth ... the rate at which my speed increases ... is 9.8 meters per second (32.2 feet per second) faster every second. Since the earth's mass is somewhat greater than my mass but the force on it is the same as the force on me, the earth accelerates toward me at a somewhat lower rate.
If a person is attracted to the center of the earth by N gravitational force the force of attraction of the earth toward a person is?
9.8 or 10 Newtons to be exact. The gravitational force stays the same as long as you are on earth.
How long does it take to get to the center of the earth from the surface?
Depends on your speed.
How long energy sun take to get to earth?
Energy, in the form of radiation, takes about 8 minutes to reach from the surface of Sun to the surface of Earth.
What is the magnitude of the gravitational force between the earth and a 1-kg body?
The earth's gravity varies a bit from the equator to the poles and also from sea level to altitude. Fortunately we have a definition for "standard gravity" on earth, and it's 9.80665 m/s² (32.1740 ft/s²). We'll need that, and we'll need to figure out and define force so we can measure it. Force due to gravity is the "pull" of gravity, and it is the attraction of the mass of the earth for this other mass that weighs 1 kilogram. There is a simple equation used to measure force: Force (F) = mass (m) times acceleration (a) For force supplied by gravity, we use the gravitational constant (g) for the acceleration. F = m times g We know the gravitational constant, so we'll just plug it in. And we'll simply plug in the mass you asked about, which is 1 kilogram, to come up with this: F = 1 kg times 9.8 m/s2 That means you've got 9.8 kilogram meters per second2 for your force. Force is measured in Newtons, and a Newton is 1 kilogram meter per second 2 so if you have 9.8 kg meters / second2 then you have 9.8 Newtons acting on your 1 kg mass.
Can gravity on earth change?
Yes, definitely. If a substantial piece of the Earth were to break off and sail away,then the force of gravity on the surface of the remaining piece would be substantiallyless than it is now.As long as the Earth's mass doesn't change substantially, however, the accelerationof gravity on or near its surface, and therefore the weight of things located in thatneighborhood, doesn't change.
Which planet has a great storm happening on its surface the size of earth and how long has it been goin on for?
Earth
How is something plumb if the earth is rotating?
Inertia; the string and weight are moving with the earth (otherwise they wouldn't be in the same place on the surface for very long). The only force available to act is gravity, which pulls directly downward and makes the bob plumb.
