-- If your mass is 'm', then your mass is 'm', regardless of whether you're on the earth,
2 earth radii out in space, or on the moon. Mass doesn't change.
-- On the surface, your distance from the center of the earth is 1 earth radius. Weight is
inversely proportional to the square of the distance from the center of the earth, so at a
distance of 3 earth radii from the center, your weight is 1/32 = 1/9th of your weight on the
surface. If your mass is 'm' then your weight on the surface is mg = 9.8m newtons, and at
3 earth radii from the center it's 1.089m newtons (rounded).

How much weaker does gravity get when you get farther away from the earth?
The force of gravity between two objects is inversely proportional to square of the distance between their centers. For example: -- If the distance between two objects doubles, the gravitational force between them drops to 1/4 of what it was. That's 1/22 . -- If the distance between two objects gets multiplied by 5, the gravitational force between them drops to 1/25 of what it was. That's 1/52 . -- If the distance between two objects gets multiplied by 10, the gravitational force between them drops to 1/100 or 1% of what it was. That's 1/102 . Right now, the center of you is about 4,000 miles from the center of the Earth. If you doubled that ... went 4,000 miles straight up ... the gravitational force between you and the Earth would drop to 1/4 of what it is when you're here on the surface.
What is the distace of the earth in the sun?
The distance from Sun to Earth is about 150 million kilometers. Whether you take the surface or the core of the Earth (or the Sun) doesn't make much difference, since the radii of Sun and Earth are quite small, compared to the distances. In any case, I believe that the distances are usually specified from center to center.
What is the communication delay between earth and mars?
Given the following approximate radii for Earth and mars orbits: Earth = 149,598,261 km Mars = 227,939,150 km The shortest distance between the two is the difference between the two, which yields 4minutes 21seconds for radio to go that distance. The longest distance between the two is the sum, which yields 21minutes.
What exoplanet is five times the radius of earth and five times the earths mass?
No planets have been found that are 5 Earth-masses and 5 Earth-radii.
Is Uranus Bigger than Neptune?
The Radius from the Center of Neptune is 24,622 km, (15,299 mi) while it is 25,362 km, (15,759 mi) for Uranus. So Uranus is bigger than Neptune, but Neptune has a greater mass. In other words Neptune is smaller but denser. Neptune has a radius of 3.88 Earth radii while Neptune has a radius of 4.01 Earth radii. In terms of mass, Neptune is 17.15 Earth masses while Uranus has 14.536 Earth masses.
How much weaker is gravity at 30 Earth radii?
Gravitation is inversely proportional to the square of the distance. On the Earth's surface we are at 1 Earth radius from the center. 1 / 302 = 1/900.
A man whose mass is 80 kg on the earth's surface is in a spacecraft at a height of 2 earth radii above the earth's surface His weight there is?
20kg=====================================Another contributor jumped in:The man's mass doesn't change. He carries 50 kg with him wherever he goes.But his weight changes, depending on the acceleration of gravity where he is.Weight = (mass) times (acceleration of gravity).So we need to find the acceleration of gravity at 2 radii above the surface.The acceleration of gravity is proportional to the square of the distance from theplace to the center of the earth, and on the surface, it's 9.8 m/s2 .On the surface, you're 1 radius from the center. At 2 radii from the surface, you're2 more radii from the center, or 3 radii all together. So your distance from the centerhas tripled.The acceleration of gravity is 1/32 of its original value, or 1/9th of 9.8 .9.8/9 = 1.089 m/s2 at that position in space.The man's weight is (mass) times (acceleration of gravity).On the surface, he weighs (50 x 9.8) = 490 newtons (110.2 pounds).Out there at 3 radii from the center, he weighs (50 x 1.089) = 54.4 newtons (12.25 pounds).
All radii of a circle are?
All the radii of a circle are of equal length. The radius is the distance from the center of the circle to the out edge. Having equal radii is what defines a circle.
What is radii in chemistry?
The distance from the center of the nucleus to the outer "edge" of the electron cloud.
How does acceleration due to gravity changes with altitude?
The acceleration of gravity ... on or near the Earth, for example ... is inversely proportional to the square of the distance from the center of the Earth. So it diminishes as you rise from the surface. When you have ascended to an altitude of one Earth radius ... about 4,000 miles ... your distance from the center is then two Earth radii, so the acceleration of gravity has shrunk to 1/4 of its value on the surface.
What is the difintion for radius?
A radius is the distance from the center of a circle, to the border. In a circle, all radii have the same length.
Why is the distance between the earth and moon given as an average?
the earth moves in a slight elipse around the sun so the distance is an average of the different radii of the elipse
What force of gravity exists at two times the Earth's radius?
Assuming you mean from the center of the Earth: 1/22 = 1/4, that is, 1/4 the gravity at the Earth's surface. If you mean two Earth radii from the surface, then the distance from the Earth's center would be 3 times as much, and the force would be 1/9, compared to the Earth's surface. _______________________________ The force of gravity changes with the reciprocal of the square of the distance. So if the distance is increased by a factor of 2, the force will DECREASE by a factor of two squared, or 4. So, double the distance = one-quarter the force.
What is the acceleration due to gravity at distance of 2 earth radii above earth's surface?
The force of gravity between two masses is inversely proportional to the square of the distance between them. So when you move from (1 earth radius away from the center) out to (10 of them), the force between you and the earth becomes 1/102 = 1/100 = 1 percent of what it was originally. Notice that gravity doesn't "become weaker" out there. It still follows exactly the same physical laws. And in precise accordance with those laws, the mutual gravitational force between you and the earth becomes 99% less than it is at the earth's surface.
About how far away is the Moon in terms of Earth radii?
About 60 Earth radii.
What is the difference between a radii and radius?
'Radii' is the plural word of the 'Radius'. Because radius is the distance between neucleous to electron cloud. But radii is the distance from ions distances.
Did all radii of a given circle are equal in length is this correct explain?
Yes, all radii of a given circle have the same length. A circle is defined as all the points on a plane that have a specified distance from a given point, called the center. Any segment from the center to the circle is called a radius (plural radii). Thus, by definition, all such segments (all radii) have the same length.
