The mass of the Earth is determined by measuring the gravitational pull it exerts on objects. Scientists use the laws of physics and observations of the Earth's orbit to calculate its mass.

How to find out weight of the person in the moon if we know the mass in the earth?

weight= mass x gravitational acceleration. thus if you know the mass and knew that the gravitational acceleration of the moon is 1/6 of that of the earth it is an easy calculation to get the objects lunar weight.


Will earth be different if the earth was half its mass?

It the earth was half its mass, then it might only be able to hold half the atmosphere. In this case, it may not be able to maintain many species of life as we know it.


What is the moon's mass compared to the earth's mass?

1 earth mass = 81.78 moon mass (rounded)1 moon mass = 0.01223 earth mass = 1.223% of earth mass (rounded)The mass of the moon is only 1.2 percent of the mass of Earth.


Is the mass of the moon greater than the mass of the earth?

No. The mass of the moon is a fraction of the earth's mass.

How can we end the gravity of the earth?

As far as we know presently, it is utterly impossible to "end" gravity; it is a fundamental property of mass. Anything that has mass has gravity.


What is earth's mass as a percent of Jupiter's mass?

Jupiter has a mass that is 317.8x greater than that of Earth. In other words, Earth's mass is equal to about 0.3% the mass of Jupiter.


How do you change an object's mass on earth to its mass on the moon?

The object's mass is the same wherever it is. Mass doesn't change. What changes is the object's weight.The weight depends on what other mass happens to be nearby.When you know the object's weight on earth, multiply that by 0.1633 to find its weight on the moon.If you don't need it that close, it might be easier to just divide the earth weight by 6.

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.)
