Why would a person weigh more on earth than on the moon?

Answer 1

actually you would weigh less on the moon than you would on Earth. The conversion is that on the moon you weigh 1/6 of what you do on Earth. This is because the magnetic field on the moon is less than that on Earth. Therefore, there is less of a force holding you to the surface of the moon than the surface of Earth.

Answer 2

On the Moon you weigh about one sixth what you weigh on Earth.

Mass:

To understand why, we start with mass. Mass, as it appears in Newton's laws of motion is the same "mass" that enters his law of gravitational attraction and this mass is the same on Earth as it is on the Moon or anywhere else in the universe. (If you eventually learn about the theory of relativity, there this is called the rest mass.)

Your mass is always the same and it always takes the same amount of force to accelerate that mass at a fix rate. If you step on a scale on the surface of the moon, you measure the gravitational pull of the moon on you and that is one sixth the gravitational pull measured on the surface of Earth. The same scale will show different weights on the Earth and the Moon.

There is a reason that the moon has less gravity than earth does.

Gravity:

We know how gravity works because we know Newton's law of gravitational attraction which says there is a force in nature galled gravity and the force acts between all pairs of objects in the universe, being proportional to the mass of each object and inversely proportional to the square of the distance between the objects. When one speaks of the "distance between to objects" in this case one takes that to be the distance between the centers of the objects. (This idea of a "center" means center of mass really, and it is what one thinks of intuitively.)

The Answer:

The direct answer to the question takes the two variables of mass and distance from Newton's law of gravitation and sees how they balance out. (a) As a person on the surface of the moon, the force of the moon on you is lessened because the mass of the moon is less than the mass of the Earth. (Earth has 81 times the mass of the moon.) (b) The Moon force is increased, however, because you are closer to moon's center since the moon is just over a quarter (.27) of the radius of the Earth.

Finally, the force goes as the inverse square of distance (13 times larger) but proportional to mass (Divide by 81.) and you get about one six the force. (Actually, it works out to .166 if you use the accurate numbers for mass and radius.)

Your moon weight about one six of your Earth weight.

Answer 3

On the moon surface, the value of acceleration due to gravity is approximately equal to 1/6 th of that value on Earth. The value of g on earth is 9.8 m s^ -2 ,that of moon is 1.6 m s^-2 .since value of g on moon is less than that on Earth, a man can jump higher on the moon than on the Earth.

Answer 4

Because the calculation of weight uses the formula W=mg, where W is wieght, m is mass and g is gravitational pull. Your mass (e.g. in kilos or pounds) does not change between places (unless you diet/eat/grow etc.) as it is a measure of inertia or matter. However gravitational pull does differ between the Earth and the Moon, and is lower on the moon, therefore your weight (measured in Newtons because it is a force) would be lower on the moon if you retained the same mass.

Answer 5

yes Because gravity is 1/6 difference on Earth than on the moon.

Answer 6

Yes. The surface gravity on the Moon is about 1/6 what it is on Earth. Therefore, things on Earth weigh 6 times what they do on the Moon.

Answer 7

On Earth there is gravity pulling you down with harder force, but on the moon there is not that much gravity so you could float and weigh less because it's not pulling you down so hard.

Answer 8

Earth has more gravity than the moon, that is the reason why you are lighter on the moon.
