How much difference is there between a astronaut's mass on earth and on the moon?

Answer 1

There is no difference in an astronaut's mass on earth and on the moon. Mass is constant regardless of where you are in space.

There is a difference in weight (Weight = mass x gravity.); since gravity at the earth's surface is about 6 times greater than the gravity at the surface of the moon, the astronaut would weigh about 6 times more on earth than he/she does on the moon.

Again, I can't stress this enough: the mass would not change. So the answer is, "no difference".

Answer 2

The moon is being pulled by the earth and that proves the there is a gravitational force between the two places. Therefore, the astronaut will never have absolutely zero weight at any point in between the earth and the moon. The weight of the person gets less and less in regard to the gravity of the earth but as he gets closer to the moon the weight increases in regard to the gravity of the moon. Using the equations for both gravities, you have to find the minimum point via calculus. Total Force (F) = GMa/R^2 + Gma/(K-R)^2, where M is the mass of the earth, a = mass of the astronaut, m=mass of the moon, K = distance between the earth and moon, and R = distance between the earth and the astronaut. You do the math and take the derivative and find the minimum. you should find the value of R, the distance between the earth and the person, where the force is at minimum.

Answer 3

There is no difference between an astronaut's mass on Earth and the moon. Mass is an intrinsic property of the object that does not change depending on location. What you're referring to is the difference in weight (which is mass times force of gravity). On the moon, the gravitational force is about 1/6 that on Earth so an astronaut's weight will be 1/6 of his/her weight on Earth. Weight and mass are generally used interchangeably because on Earth everyone is subjected to the same gravitational force, so it cancels out.

Answer 4

Hello It's great to meet Royalty. The King in person. An Astronauts mass or weight is exactly the same on earth as on the moon.The difference is gravity. The moon's gravity is considerably less than earths. The moon spins at a slower rate than earth. If by some natural misfortune earth stopped spinning; we would all be reduced to blobs, Not a pleasant thought.

Answer 5

The mass is the same. Regarding the weight the ratio is about 6:1.

Answer 6

Whether an astronaut is on earth or on the moon, his or her mass remains the same.

Answer 7

there is no difference of mass on the earth and the moon. your weight on the other hand, does differ. lets say your MASS is 100Kg(i dont know how to convert into pounds, but 100Kg is about 230lbs.) so 100Kg x 9.8(earth gravity) = 980N. that is your amss on earth. the moon's gravitational pull is 1.64. therefore 100Kg x 1.64 = 164N therefore there would be a 816N difference. you can find out how much you would weigh in Newtons on the moon by doing this.

Answer 8

the mass is the same just the gravitational pull of the moon is 1/6 that of earth.

Answer 9

There is no difference in mass but the astronaut would weigh a lot less, maybe 65 percent less.

Answer 10

Difference in weight is 6 times, but mass is the same in both places.

There is a great deal of confusion about weight and mass.

Mass is properly measured in either kilograms or slugs, but most people have never heard of slugs.

Weight is properly measured in Newtons or pounds, but most people have never heard of Newtons.

On Earth 1 slug weighs 32 pounds and 1 kilogram weighs 9.8 Newtons.

On the Moon one slug weighs 5.3 pounds and one kilogram weighs 1.6 Newtons.

The confusion is that 99.999% of the world insists on calling kilograms weight. They say 2.2 pounds equals one kilogram. But it doesn't. What they mean is that one kilogram weighs 2.2 pounds on Earth. What they don't ever say is that one kilogram weighs 9.8 Newtons on Earth.
