Weight depends on measuring the attraction between two objects, such as a person
and the Earth. It is actually a mutual attraction between their masses. The mass of
the Earth, however, can be calculated from its gravity.Mass of the EarthNewton showed that, for spherical objects, you can make the simplifying assumption
that all of the object's mass is concentrated at the center of the sphere. The following
equation expresses the gravitational attraction that two spherical objects have on one another:
F = G * M1 * M2 / R2
R is the distance separating the two objects.
G is a constant that is 6.67259x10-11m3/s2 kg.
M1 and M2 are the two masses that are attracting each other.
F is the force of attraction between them.
Assume that Earth is one of the masses (M1) and a 1-kg sphere is the other (M2).
The force between them is 9.8 kg*m/s2 -- we can calculate this force by dropping
the 1-kg sphere and measuring the acceleration that the Earth's gravitational field
applies to it (9.8 m/s2).
The radius of the Earth is 6,400,000 meters (6,999,125 yards). If you plug all of these
values in and solve for M1, you find that the mass of the Earth is 6,000,000,000,000,000,000,000,000 kilograms (6 x 1024 kilograms), or
6 quintillion metric tons (6 x 1021 tonnes).
As odd as it sounds, the weight of Earth is exactly zero, because the Earth is in
orbit around the sun, and as such, the Earth is free falling in space around the
sun.1 Any object in free fall in space, including an object in orbit, is weightless.
That is why astronauts are weightless when in orbit around the Earth.
Weight is a characteristic of an object as it relates to the gravitational field it is
resting in. You would have to take the earth to a much more massive world, like
Jupiter, and ignoring the difficulties caused by the gaseous make up of the
planet, put the Earth on a rather large scale to see what the Earth "weighs"
there. Of course, its weight would change based on its distance from the center
of gravity of the attracting object. On Earth, weight changes negligibly at any
altitude within the atmosphere.
The mass of the earth is another matter. The mass of the earth is 5.9736Ã—1024 kg,
or about 5,973,600,000,000,000,000,000,000 Kg.
1 An orbit is a special case of a free fall condition. As the orbiting object falls downwards, it
also travels transversely (sideways) at such a rate that its falling trajectory projects a curve
that always remains the same distance from the planet's surface.
From a different perspective:
The following experient was performed. Gravitational forces always occur in pairs,
between the centers of two masses, and the two forces are equal, so that the
force between me and the earth is what I call my "weight". If this is generally
correct, then the weight of any object depends on the other object to which
it is gravitationally attracted at the moment, and if that's true, then I can weigh
the earth on me.
In my laboratory, I placed a tiny mirror on the floor. I then took a bathroom scale
out of a cabinet, inverted it, and placed it top-down on the floor, with its digital
display visible in the tiny mirror. I then alighted upon the scale, placing my full
body upon the surface that is normally the bottom of the scale ... the surface
with the label, the rubber feet, and the battery door on it. In this way, I was
able to weigh the earth in my gravitational field, and (just as Sir Isaac might
have predicted) it was precisely equal to myweight when measured in the
earth's gravitational field.
It would seem that in order to accurately quote the earth's weight, the question
must specify the other object to which the earth is being gravitationally attracted,
and must also specify the other object's mass, and the distance between the
centers of mass of the earth and the other object. As any of these details
changes, so too does the earth's 'weight' change!
Your weight on earth is about 6.13 times as much as your weight on the moon. Your weight on the moon is about 0.16 of your weight on earth.
The weight on the Moon is about 1/6 of the weight on Earth.The weight on the Moon is about 1/6 of the weight on Earth.The weight on the Moon is about 1/6 of the weight on Earth.The weight on the Moon is about 1/6 of the weight on Earth.
No Your weight on the Moon is 1/6 of your weight on Earth
Multiply Earth weight by 0.379 .
AS WE KNOW, that there is the force of gravity at the center of Earth, if every part or portion of earth has its weight then net weight of the earth will be zero........
Your weight on Pluto will be your weight on earth multiplied by 1/166
Relative to what? On the Earth - 1kg.
your weight is one sixth on the moon than how your weight is on earth
your weight is 1.13x your earth weight :)
The weight of a person is not constant at all places on the Earth. The weight becomes zero at the center of the earth or far away from the Earth.
In theory, at the center of the Earth you would have no weight.
it is your weight on earth divided by 10
On the Earth, your weight will be about 6 times the weight on the Moon.
Multiply weight on Earth by 1.064. So if you weighed 100lb on Earth you'd weigh 106.4lb on Saturn.
The force of gravity on the moon is approximately one sixth that of the earth. The direct variation formula for weight on the earth compared to weight on the moon would be weight on earth divided by 6 is equals to weight on the moon.
As you get farther from the center of Earth, your weight willDECREASE
Weight is greater on earth than in space due to gravity.
Mass of an object is 10kg what is its weight on the earth?
On the Earth, the object weighs 6.04 times as much as its weight on the moon.
weight on earth=x weight on moon=z formula=x divided by 6 = z i think i splaind it right EXAMPLE: weight on moon=weight earth divided by gravity weight on moon=250N divided by 6 weight on moon=41.66. an object that weight 250N on earth, weight 41.66N on moon. A+=6
Weight is what we call the amount of the gravitational force between the Earth and an object on the surface of the Earth. It works both ways. Your weight on the Earth is also the Earth's weight on you.
Determine the weight of a person on the Moon whose weight on the Earth is 183 lb.
You weight on the moon is 16.5% of what your weight is on Earth.
