You don't need to spend millions to know that. The gravitational force experienced by say a person is not the same at all points on the planet, for a variety of reasons, such as the fact that the earth is not a perfect sphere, that it'll depend on your altitude above sea level, whether you are next to a large mass (such as a mountain). Doesn't vary by much, but it varies.
true but as you seem to want to be pedantic g is the gravitational field strength at a point in space (in its general definition) the idea of the 'force of gravity' being the force of attraction between 2 bodies of masses m1 and m2 is only the same as g if one of the masses has a value of
1kg g=-Gm/r^2 F=-Gm1m2/r^2 so its trivial to see that F=g if m1 or m2 is 1kgIn message , "dennis@home" writes
No - It clearly uses a capital "G" if you look
Ha ha! Nearly...!

Of course it varies, while I was in Indonesia, a friend there was making a gravitational map of Java for the BGS
There seems to be data showing that G is changing over time (IIRC there are also similar claims for c) and that it has a direction in space ( somewhat like the aether)
While it may or may not be true, the jury's still out
I am not being pedantic, I am using it in the context of the thread where it is a defined constant. The post I made was a specific response to the ARW idiot post about it being different on other worlds, which it isn't. As I sated the gravitational force on Earth does actually vary unlike "g" in the context of the thread.
The other posts are just the usual idiots trying to score the mythical points they appear to be playing for. Shame they are wrong as usual.
You're not, of course?
Dennis, sweetheart, give it up sunshine, really. Everyone and his dog understands that you're an idiot. Is that not obvious to you? My god but you must have thick skin.
He falls for it everytime and then blames the spellchecker.
You can argue about something else if you want to but I am not going to.
No, I just like to point out that ARW is an idiot occasionally when he tries to claim I am wrong. If he didn't post the cr@p then I wouldn't respond as I never start these "arguments".
So you think ARW was correct, I guess that makes you as big an idiot as he is.
You started the argument. I just mentioned that g may be different on Dennisworld than on Planet Earth.
So 20x smarter than you then:-)
So why did you bring G into the thread and then suggest there is millions being spent on it when it has not a lot to do with this thread. g varies because of other things than the value of G.
Which bit don't you understand? The bit where it says g is defined as 9.80665? Or the bit where it say g is not G? Or maybe you just can read?
It is amazing what a retard can google

Which bit did you not understand?
g = 9.80665 on Planet Earth.
You calling denboi's nurse a retard?
It isn't. g subscript n might be, but that's a different thing.
You seem to be having trouble with this. It's not /defined/ as that any more that atmospheric pressure is defined as 1013.25 millibar. Both are standardised 'normal' values for quantities which vary.
g = 10 ms^-2 is quite good enough for most purposes, although we always used 9.81 when I was at school...
