Does gravity push or pull?

Is there a such thing as Neutrinos?

Is your weight absolute 0 at the center of the earth?

Tesla said his theory of gravity applied to all things no matter how small or how big. Eisnteins and Newtons theory doesn't. Will the world ever know?

If the world exploded, where would all the ghosts go?

I thought it would be fun.

I like the discussion in the other thread, I just feel like it needs a better home.

[_iffy]

alright then, hopefully jah,dur can prove his stupids here (i am aware of the bad grammer)

most people thing gravity is mass x acceleration of gravity.
this is fine on earth but...the real formula is...

Gravitational force = (G * m1 * m2) / (d2)

Where G has the value of 6.67 x 10E-8 dyne * cm2/gm2

so any two objects that have mass have a gravitation force drawing them together.

I'm not touching these
but in the centre of the earth... you would float like vishnu, there would still be gravity but it would be from
all sides and angles so they would be in balance.

I think einstien used the above formula but i'm not sure so i can't really comment on that.

all the goshts would go to that planet all the mormons are going to. You know the one were every girl is pregnant. Always. Forever.

that formula i gave you calculates 9.98m/s^2

That formula is universal. It doesn't matter what planet your on. F=mg is a shortcut.

Gravitational force = (G * m1 * m2) / (d2)

d= distance between
G=6.67 x 10E-8
m1= mass (kg) of first object
m2 = mass (kg) of second object

You use this formula when looking at planets, stars, and orbits.
eg: Two satalites in orbit have gravity, from the earth, the sun, the moon, even mars, and each other.

You use it to find the gravitation constants. Like the force of gravity on the moon.

That formula is correct puck.

Gravitational force = (G * m1 * m2) / (d2)

that doesnt explain gravity - it just describes it

the real question is why are these objects attracted to each other in this manner . . .


I believe the ghosts would just go into the ether

its always used...not just when talking about planets

It isn't always used. It is only used most of the time. For objects extremely small or extremely large the equation does not work. Newtons was more obviously wrong that is when Einstein made a better one. It still encorporates Newton's in a normal range but Newton's is more wrong than Einstein's in extreme ranges. As damam said we don't know why.

ummm....actually your wrong iffy....
but at least you tried....
F=mg....everywhere....g just changes depending on where you are....
what you may have meant to say was that most people think g=9.8...that may be true on earth...but everywhere else
...........

You are still confusing gravitatinol field and gravitational force.....

You are the tool PUCK is the #1 thread crapper and you removed your post becuase he told you too.

^^ your an idiot

their no such thing as a gravitatinol field.
It's not like sheilds in star trek.
It's a force directed from the centres of two objects.

FYI - i removed my post because it had nothing to do with jesus being a jew, also because of Throwingstrikes
request. Seeing how it was this thread, i felt it was the polite thing to do. But for your knowlegde a nuclear reactor works by putting radioactive material into a pot of water to make it boil. The steam is used to power turbine generators. It's nothing like a particle accelerator.

puckSR are we arguing? i can't tell any more. You just agreed with me, after your earlier post where you dissagreed. **F=mg is a shorcut using a calculator**(sorry for the confusion)

one thing to add with f=mg is it doesn't incorporate distance. Like, why aren't we all sucked into black holes?
Their suppose to have near infinit mass?

F=ma is law but f=mg works.

throwingks You can use that formula anytime. It's just sometimes the result is so negligible whats the point.

[damam]

actually there is such a thing as gravitational field

I know enough about gravity to know that i really dont know or understand it at all . . .

The proposed model in my physics classes was that matter created curvetures in space making the shortest distance in 4 dimensions between the two bodies, well much shorter than they appear. . . so when you drop an object your witnessing the trajectory moving in curved space taking a geodesic path which we then interpret as an attractive force.   (its been a while since I have even thought about this but I think I got it right).

I could be wrong but i believe while I was learning this, the theory had been cast in considerable doubt

Gravitational Field
The gravitational field at any point is the gravitational force on some test mass placed at that point, divided by the mass of the test mass. The dimensions of the gravitational field are length over time squared, which is the same as acceleration. For a single mass  (other than the test mass), Newton's law of gravitation tells us that

1 of many sources with it definition and impirical equation.

ok we agree.

No....Im not....
If you think I am...then your misunderstanding my post
Wow....that is just blatantly wrong....
Ummm...
I dont even know where to start....
In this case the word "field" refers to the range of the interaction...
like an electromagnetic field...
you almost got the idea when you asked about the whole distance thing earlier.
Ok...here is what you are misunderstanding

F=ma   LAW
F(g)=mg LAW...
F(g) is gravitational force
g is acceleration due to gravity

this is always going to be true...as long as Newton's second law is true....
what you are not understanding is that g is not a constant....
if you consider g a constant...i.e. g=9.8 then yes...this is a simplification
once again...Im really just arguing semantics...

Based upon your post dont, YOU do not fully understand the concept of a gravitatinal field.

YOU are explaining how objects ACT in the presence of a gravitational field.

We do not know exactly what causes a gravitational field, LAST I read the gravitons were all the rage.

But, I am sure _iffy will be able to explain it better than I.

[_iffy]

Alright.
maybe i'm just thinking of gravity different.
I don't see fields, i see force acting linearly inbetween centres.
using the Gravitational force = (G * m1 * m2) / (d2) equation you get...

I can see how one might view a feild. An area close by where gravity would become significant.

But what damam's talking about i have no idea.
