How much does the earth weigh not based on gravitational attraction?

This may be a trick question. We often use the terms "weight" and "mass" interchangeably, but we use the term "weight" to refer to mass that is in a gravitational field (and generally the gravitational field of earth).
.
If a person weighs 150 pounds, it means that we have used "pound" as a reference, and that involves (or invokes) the effect of the pull of the earth on that person. But that person has mass that is independent of gravitational attraction. A person who has a mass of 150 pounds has that mass no matter where he may be. That person is weightless in deep space where there isn't anything of substance around to exert a gravimetric pull on the person. Mass is present, but there is no weight.
.
The earth is not said to have weight. Instead, it has mass, and that mass is a bit short of 1024 kilograms.

Why do you weigh more on Jupiter than on Earth?
because Jupiter has a bigger mass than earth and the more mass means the more gravitational attraction
What is the measure of the earth's gravitational attraction?
A single object doesn't have a gravitational attraction. The gravitational force between two objects is proportional to the product of both of their masses. So the force between the earth and any other object ... like a person ... depends on the mass of the person, just as much as it depends on the earth's mass. You can't tell the strength of the earth's attraction of an object until you know the object's mass. (In other words, you don't know how much a person on earth will weigh until you know something about the person.)
Why does a person weigh lesser on the moon?

Gravity is the pull toward the center of an object; let's say, of a planet or a moon. When you weigh yourself, you are measuring the amount of gravitational attraction exerted on you by Earth. The Moon has a weaker gravitational attraction than Earth. In fact, the Moon's gravity is only 1/6 of Earth's gravity. So, you would weigh less on the Moon.
The force that holds things on the ground and determines how much they weigh?
That is called gravity.
Does the gravitational attraction on an object increase or decrease with and increase in altitude?
it makes no difference you will still weigh the same
Explain why the weight of an object is not the same on different points on the earth?
Weight is a measurement of the gravitational attraction of the earth to the mass of a body. Since the mass stays the same wherever the body is, the gravitational attraction must change from location to location. A body weighing 120 grams at sea level, would weigh slightly less as it was moved away from the center of gravity of the earth, for example, up a mountain. It would weigh slightly more the further below sea level it was moved. Suspending (or immersing) a body in water would also change its apparent weight, though this would be a reaction to the bodies buoyancy rather than a change in gravitational attraction. - wjs1632 -
Why do you weigh more on earth then on Pluto?
You weigh more on Earth than on Pluto because Earth has a higher gravitational pull than Pluto does.
If the mass of the earth stayed the same but it had a radius of 1000 miles. you would weigh more or less?
You would weigh more, because if the earth had a smaller radius, the gravitational force of attraction would be stronger on the surface. Isaac Newton proved that the gravitational force due to a solid sphere (like earth) of mass M is the same as the force due to a point mass M at the center of the sphere. If you have mass m, and are standing on the earth at a radius R from the center, Newton's law of gravitation gives us the force of attraction (or weight) between you and the earth: F = G*m*M/R^2 (G is the gravitational constant) Now, if the earth's radius is decreased from its current radius of approximately 4000 miles to 1000 miles, everything stays constant except for R, which is decreased by a factor of 4. However, because we divide by R^2, the gravitational force would be 4*4=16 times greater! If you weigh 150lbs on earth, now you would weigh 2400lbs!!!
How much does Earth weigh in newtons?
"Weight" is the two-way gravitational attraction between two objects. A single objectin space all by itself has no weight. In order to measure its weight, you need to haveanother object around to set up a mutual gravitational attraction, and then the weightwill depend on the mass of the other object, and also on the distance between thecenters of both of them.If I am the other object and I am located one earth-radius from the center of the earth,then the earth weighs 185 pounds, or about 822 newtons.
How does the gravitational force exerted by earth on the sun compare with the gravitational force exerted by the sun on the earth?
The gravitational forces on two objects are equal. You attract the earth with a force equal to your weight. Whatever you weigh on earth, that's exactly how much the earth weighs on you.

What is the gravity on Alnilam?
Alnilam is a blue supergiant in the constellation Orion.It has about 40 times the mass of our Sun so it's gravitational attraction is about 1,117.6g or 1,120 times that of Earth.If you weighed 100lb on Earth, you would weigh 108,288lb on Alnilam.
