But, gravity is the force acted upon an object, pulling it to the earth's core. Therefore, the weight of the object is probably equal to the force of gravity acting upon it. So, that also means that gravity is also acting as a magnet, pulling objects to the earth's core. So you are partially correct, Ama.

In a vaccuum, everything pretty much weighs the same. In theory, a hammer and a feather weigh the exact same on the moon because there is no gravity up there. But they still fall down, obviously, so this data also supports Ama's theory of molecules not able to support the falling object.

At least, I believe that's how that happens.

...I don't think that made any sense. Maybe I should study physics more.

gravity is measured in g and it is 9.8 m/s^2

but that can also be the rate of an object falling through air, because it is not the same as an object sinking

You see, what I am saying is the the earth isn't pulling objects towards it, otherwise the force of that would prevent us from jumping, or flying and such, unless you have a faster acceleration than 9.8m/s^2

it may seem that way because everything falls to the ground, but that happens because air isn't not strong enough to support the object.

actually a vacuum does not affect the mass of an object. A Hammer will be heavier than a feather but it's weight is greatly affected. So a hammer may feel like a feather, but really it's mass has not changed.


because Weight is Fg and it is equal to mg (mass times gravity)

since the gravity would equal zero or something different on the moon and other planets, the weight will change but not the mass

Then mass would have to equal zero if the gravity is zero. Therefore the feather and the hammer will both have equal masses, and equal weights. If g=gravity and if g also equals zero, that would mean that the mass and weight would be the same. Zero.

And because air can't support an object is because of the weight. And the weight is the amount of force gravity acts upon an object. Though you are correct in saying that the objects are merely falling in theory because air cannot support them due to the weight or whatnot. This could be entirely correct.

no, Fg means weight, the g in Fg isn't gravity it is like f(x) which equals y

mass x gravity = Weight

mass is 100Kg
Gravity is 0 m/s^2

thus

100 * 0 = 0N

mass is still 100, but weight is 0





this air molecules act as shown in the picture, they are not together, so they take up more area with less actual molecules, this cannot support an object, so it falls.

Although now I am questioning whether the 9.8m/s^2 is a constant or not, because obviously I need to test this out

Ah I see. That's a good question, you should test that out. So, am I right in thinking that you are saying that the falling of an object has nothing to do with its weight? It's more to do with its mass and volume?

weight is a force really.

It is the force of gravity acting on the mass
I am thinking that objects will fall at different speeds because their mass is different, i.e. the mass of a piece of paper is not as heavy as a glass cup, thus the acceleration of gravity will make the glass cup fall faster than the piece of paper

So it has everything to do with both mass and weight?

just really mass


weight is just really the force that is being applied

Ah I see. Weight is the force in this theory, therefore mass is what it's being acted upon. Correct?

yes

Ah I get it now.

okay

So I do agree with you.
