Would the density of a person be the same on the surface of the Earth as on the surface of the moon?

No, it is much different.
2nd Answer:
Back up a bit. Your weight on the Moon would be 1/6 of your weight on Earth, but your density is the same anywhere.
The reason is that your MASS is the same anywhere, and its amount does not depend on gravity like weight does. (Mass just happens to be the same as your weight on Earth)
Since your mass is the same amount anywhere, then so is your density is the same anywhere, too.

∙ 12y agoThe brick's weight will stay the same however the masswill differ in space. It depends on the amount of gravitational pressure the brick is placed under. The gravity on earth is approximately 10m/s2 and every planet has a different gravity. The mass of the brick will depend on the gravitational pull of the planet. So, to answer your question, the brick would weigh less because it was put under less gravitational pressure from a planet.

∙ 13y agoMass vs. Weight
To understand the differences we need to compare a few points:
1) Mass is a measurement of the amount of matter something contains, while Weight is the measurement of the pull of gravity on an object.
2) Mass is measured by using a balance comparing a known amount of matter to an unknown amount of matter. Weight is measured on a scale.
3) The Mass of an object doesn't change when an object's location changes. Weight, on the otherhand does change with location.
The weight of a 100 pound "earth" brick will be only about 17 pounds on the moon. The mass of the brick doesn't change no matter where the "matter" is.

∙ 11y agoDensity is mass/volume.
Now this could be a trick question to make you understand the difference between mass, and weight but....
Without a space suit or any other kind of external pressure, your exposed body would expand on the Moon, with messy consequences.
However, within a spacesuit, set to equal Earths atmosphere, your density will stay exactly the same, as mass is constant, and your volume will be kept constant by the spacesuit.
__________
Even at substantially lower air pressure - for example, while climbing high mountains, where the air pressure is less than half of normal surface pressure - your body expands by only a very tiny fraction.
__________
From [See related link]
In the absence of atmospheric pressure water will spontaneously convert into vapor, which would cause the moisture in a victim's mouth and eyes to quickly boil away. The same effect would cause water in the muscles and soft tissues of the body to evaporate, prompting some parts of the body to swell to twice their usual size after a few moments

∙ 13y agoMass and weight are two different things. The mass of an object is measured in kg, which remains constant regardless of the local gravity. The scientifically correct way of describing weight is by using Newtons, the weight of an object is equal to the mass x the local gravitational field strength, which on earth is 9.81. so a 10 kg mass on the earth weighs 98.1 Newtons.
The confusing thing here is that we more often refer to the weight as the mass. We dont travel away from the earths surface much - the local gravitational field remains constant for us here on the surface, so we have become used to just referring to weight what it is in kg.
On the moon there is less of a gravitational pull (because the moons overall mass is less than the earths, and gravity strength is related mass), so the weight of the 10 kg mass is now 10 x 1.62 on the moon instead of 10 x 9.81 as on earth - its 16.2 Newtons instead of 98.1 N.

∙ 13y agoMass would be constant for the same object.
Acceleration due to gravity would be only one-sixth of that on Earth, due to the lower amount of mass in the moon.

Would a smaller planet than earth with the same shape and size have more gravity?
If the planet is smaller, then it can't have the same size. If you assume that a smaller planet has the same density as Earth (and therefore less mass), its surface gravity will be smaller. If you assume that a smaller planet has the same mass as Earth (and therefore more density), its surface gravity will be greater. This is because we would be closer to the planet's center - or to the planet's matter in general.
Why would a person weigh less on top of a mountain than on Earth's surface?
Because the mountain is farther away from the gravitational centre of the Earth.
What would a 150 pound person weigh on venus?
A 150 pound person would weigh 179 pounds on Neptune. The surface gravity on Neptune is 119% of Earth's surface gravity.
If a person weighs 210 pounds on earth how much would they weigh on Venus?
Surface gravity on Venus is 90.4% than of Earth, so a 210 pund person would weigh just about 190 pounds on Venus.
What causes the most rapid change to Earth's surface?
I would expect that the most rapid changes to the Earth's surface would result from the impact of a comet striking the Earth.
Would the density of a person be the same on the surface of earth and on the surface on the moon?
yes
Can the earth have the same density in the center as it does on the surface?
No it can not. We know this because we know the mass of the whole Earth (by looking at its gravity) and if the whole Earth were made of rocks of the same density as we see at the surface, there would not be enough mass to account for the gravity. The Earth must have more dense stuff in its core.
What would a 100 pound person weigh on earth surface?
Well it depends on where this person was weighed. If they were weighed on Earth, then they would be 100 pounds.
The period of oscillation of a pendulum of constant length at the earths surface is T.its period inside a mine would be?
When you go down below the surface of the Earth, the gravity will initially INCREASE. This is because Earth's density is not uniform - there is more mass concentrated closer to the center, than in the case of a sphere of uniform density. If Earth were a sphere of uniform density, the gravity would get less, once you go below the surface - because some of Earth's material would pull you upward.In any case, if you go further down, eventually the force of gravity will become less. When the gravity increases (as it does initially), the period will become shorter.
Would a smaller planet than earth with the same shape and size have more gravity?

How many pound would you weigh on Jupiter if you weigh 50 pound on Earth?
Equatorial surface gravity on Jupiter is 2.528 time that of earth, so a 50lb person on earth would weigh 126.4 lbs
Would a human be squashed by the extreme gravity on Uranus?
No. Despite being more massive than Earth, the low density resulting large diameter of Uranus result in gravity at the nominal "surface" being slightly weaker than the gravity on Earth. That being said, the "surface" does not actually exist; it is merely the level at which atmospheric pressure is roughly equal to sea level pressure on Earth. A person placed there would fall through the gaseous outer layers of the planet and would be crushed by the extreme atmospheric pressure deep within.
Density on earth is 7.9 What would be on a spaceship?
yes
How much would a 250 lb person weigh on Mars?
A 250 pound person would weigh about 82 pounds. The gravitational force on the surface of Mars is about one third of that of earth.
