### Re: Dependance of "g"

$g$ does not depend on $m$, in any theory!

Whatever $m$ is, the value of $g$ is the same, $9.8 ms^{-2}$. It is a constant independent of $m$.

We can write $2 = \frac{a}{b}$. That does not mean $2$ depends on $b$.

### Re: Dependance of "g"

Ok..according to the updated defination of function we can define function with dependent and independent variable....y=2x..here, y is depending on the value of x..so,why you want to say that in 2=ab...2 is not depending on b?

Definition of functions has nothing to do here.

Does $2$ depend on $b$? You tell me.

### Re: Dependance of "g"

If 2 = ab..you can get 2 after using the value of b in the right side of this...so....

That does not mean $2$ depends on $b$. Whatever $b$ is, $2$ is always $2$, it does not depend on anything.

as far as I know left side of a equation always depends on the right side....yes,you have used here 2 which is a constant...but we was conversing about g..this is also a constant...there are two kinds of constant....one is called wishমুলকconstant(don't konw the right english) so , it is different from 2 type constant......look if 2=ab and a=1 than the equation will be satisfy if and only if b=1 so why are you saying .............................................

### Re: Dependance of "g"

There is not such things like these.
A value $x$ is dependent on $y$ if and only if when you change the value of $y$ the value of $x$ also changes. If the value of $x$ does not change when you change the value of $y$, then $x$ is Independent of $y$.

### Re: Dependance of "g"

Ok, in the equation g=F/m we can use different value of F and m......if I take 4116 as the value of F I have to use 420 as the value of m...I can't use other value of.m..so......

A=xyz হইলে A কে x এর উপর তখনই নির্ভরশীল বলা যাবে যদি y,z অপরিবর্তিত রেখে শুধুমাত্র x এর পরিবর্তনে A এর পরিবর্তন হয়।
