How does gravitational force change if distance decreased by half?
The gravitational force then increases by a factor of 4 .
How far does your sun gravity extend?
Gravitational fields do not come to an end, they just get weaker, the farther you go from the mass which creates them. Since our sun (also known as Sol) has existed for about four and a half billion years, its gravitational field extends for about four and a half billion light years. Of course, the field is very weak at that distance, too weak even to detect. In practical terms, the gravitational field of the sun is strong enough to hold some objects in orbit, at distances of several billion miles. Comets orbit at those distances.
If the moon were twice as far from the earth as it is now the gravitational force it exert on the earth would be?
half its present value
How much of the entire moon's surface is illuminated by the sun at first quarter?
At any time, half of the entire Moon's surface is illuminated.
When is the moon gravition pull the strongest?
The mutual gravitational forces between the Moon and the Earth are strongest when the distance between the two bodies is smallest. Just like the mutual gravitational forces between any other two bodies.
What is the value of gravitational field strength on a planet with half Earth's mass and half its radius?
i guess it 's 39.2n.kg
What happen when a supernova collapses suddenly?
A supernova occurs AFTER a star collapses suddenly. See related question
How does gravitational force change if distance decreased by half?
The gravitational force then increases by a factor of 4 .
Half of the earth's surface?
Half of the Earth's surface is called a hemisphere.
Why isn't the surface of a hemisphere not half the surface area of a sphere?
The surface area of a semicircle has the round surface which is half a sphere and also has the flat surface which is a circle.
Why half of the earth's air is concentrated in the lower five and half kilometres of the atmosphere?
because of gravitational pull
What is the half life of the earth's magnetic field?
Magnetic field doesnot have a half life. Elements have half life.
What would be its relative strength at the new surface if Earth shrank to half its size?
Assuming that by "it" you mean the gravitational force, the amount gravitational force of an object with spherical symmetry (Earth basically has that) on an outside object is the same as if the entire mass (of Earth, in this case) were concentrated in the center.Thus, and assuming you mean you shrank Earth WITHOUT changing its mass, you would get half the distance, and therefore four times the force.
What is half of Earth's surface?
A hemisphere is one half of the sphere that makes up Earth's surface.
What Half of earths surface is called?
There is no such thing as half of the Earth. If you are referring to half of the spherical shape of the Earth then it will be a hemisphere.
Is the moon splitting in half?
No, why should it? There is a powerful gravitational force holding it together.
What is the source of gravitational pull on all planets?
since the sun is so hot i creates such a strange atmosphere that it turns a half of it into a gravitational pull. By Alice
