Would an object have the same density on the moon as it does on the earth?

Yes, it would have the same density. The volume of an object does not change no matter where it is. So on the moon the object would have the same mass and volume as it would on earth; therefore that object would have the same density. Density equals mass divided by volume.

∙ 11y agoIf you drop a hammer and a feather from the same height on earth, the hammer will hit the ground first as the feather is slowed down drastically by air resistance.
But on the moon, because it is a vacuum, and since the acceleration of an object is the same as the gravity i.e. a = g and the mass is not in the equation, all objects will have the same accelaration and hence the hammer should fall to the surface of moon at the same time as the feather but:
"Both will hit the moon at the same time as believed by most scientists?"
This may not be absolutely true since every object has its own gravity which is greater if its mass is greater. So the hammer has a gravity much greater than that of the feather. Therefore the combined gravity of the hammer and that of the moon (which pulls the hammer and moon towards each other) is greater than that of the feather and the moon.
As such the hammer should collide with the moon marginally earlier than that between the feather and the moon, though this difference is so minute that we assume that the collisions occur simultaneously.
However, if the hammer and feather are dropped together, then as the hammer's gravity pulls the moon towards itself, it also pull the moon towards the feather and as such the lucky feather may get a free ride and hits the moon at the same time as the hammer.
But even with this help, the feather will still take a slightly longer time to collide with the moon as the gravity from the hammer will cause the flight path of the feather to curve towards the hammer and as such takes a longer path and hence a longer time to hit the moon.
To be fair, the experiment should be done dropping the feather first, then the hammer and then see the different times taken.
All the above are valid only on the assumption that the centre of gravity is the part that hits the moon but since this is not true, we also have to take into account which part of the hammer or feather is nearest to the moon before the two objects were released !
So, the real answer is that there is not enough data for us to know which will hit the moon first !

Mass is how much "stuff" is in an object, and it never changes, but weight is gravitational pull, so it will vary
Wiki User
∙ 6y agoYes, the mass would remain the same, but the weight would change because the Moon has lower gravity subscribe to Aalivia MSP for 1,000 subscribers

How much do objets weigh on the moon than the earth?
Any object on the moon weighs 1/6th of what it weighs on Earth. For e.g., a 6kg object will weigh only 1kg on the moon.
What is the density of an object on space?
The density of space varies due to where in space you are. For example, in clouds of dust the density is much higher but in the rest of space the density is very low. It is impossible to calculate the overall average density of space as you would have to know exactly the mass of all the planets, moons, stars and dust in the entire universe and the exact area of the universe. This in itself is impossible as the universe is constantly expanding, meaning that the density of space is continuasly decreasing. Basically, even if you could measure the size of the universe and the mass of all the objects in it the answer would immediately be out of date. However, we can estimate the rough density of our solar system. I don't know the numbers but if the solar system was a room. 10m long, 3m high and 6m wide, then all the matter in the solar system would fit into a grain of sand. In short, we do not know exactly, but we know it is low.
Why does an objects gets attracted towards moon when it leaves the earth's gravitational field?
The moon orbits Earth because it is held there by Earth's gravity. The moon is going fast enough that it won't hit Earth, but at the same time is being pulled back in at the same rate it flies away. The same is true for why Earth itself doesn't fly into the sun. the sun is MUCH MUCH MUCH further away than the earth is, so it is attracted to earth because the difference in size and gravity favour the earth. If it was to be attracted to the sun, the sun would need to be bigger or closer (both of which it is doing at aconstant rate, but very gradually over a long perios of time)
Is gold non luminous object?
sun (a luminous object) emits its own light and the moon ( a non luminous object ) reflects the light from the sun to earth that's how we can see the moon. The same way gold is a non luminous object.
What would occur if the moons orbit was not tilted?
If the moon did not orbit the Earth then there would not be a day or a night. We would see the moon when it is day time.(Depending what part of the Earth your'e on.) The moon influences much on Earth. Tides, weather, even animal behavior can be affected. If the moon didn't exist, I believe that problems with a balanced gravitational pull would exist.
Would an object have the same mass density on the moon as it does on earth?
Yes.
How would the mass of an object change if it were on the moon?
The mass of an object itself does not change on the moon. However, an object's weight is less than it would be on Earth because the moon's gravity is weaker than Earth's gravity.
Why An object will weigh approximately 6 times HEAVIER on earth than it would on the moon?
Earth is a about 6 times more massive than the moon (Has more density per volume, since it's technically weightless in space) Gravity is proportional to how large a planet or moon is, so the object will be heavier on earth (a larger planet) than on the moon (a small body)
The Moon's average density is about the same as the density of which of the Earth's layers?
The moon's average density is about the same as the density of mantle of the Earth.
What is the amount of matter that an object has if the object were on the moon this would not change?
That is its mass which does not change on earth, moon, or anywhere.
What is the nearest natural object to the Earth?
That would be our "moon".
Does the earth have more mass or density than the moon?
No; the Earth has over eighty times the mass of the Moon. Our Moon is overall about three fifths the density of the Earth; which is itself a scientific curiosity since this would mean the lunar core has an unusually low density.
What would an object that is 1 newtons on earth be on the moon?
One Newton on Earth is about 0.1653 newtons on the moon.
How does the weight of an object on the earth's surface vary with its weight on the moon?
An object will weigh approximately 6 times HEAVIER on earth than it would on the moon.
If an object on the moon weighs 42 lbs how much would the same object weigh on earth?
The weight of 42 pounds on earth would weigh 7 pounds on the moon.
What object in solar system is closet to earth?
That would be Earth's Moon, 'Luna'.
An object from earth would weigh on the moon?
about a 1/6th
