Big G



This is a excerpt from The gravity formula proof tab. First study the G-less gravity equation tab.


the orbit height. ... 35786km    ( 42164000m-- o.r.) geostationary

First we'll use the centripetal force formula to find the g force per 1000kg and check that against our new equation.


F =m.r.4pi2/T2

=1000 x 41894987 x 39.4784/7464960000

=22.5915kgF     221.56N      0.22156N/kg


Nm-- Fg= ( rt mb) x ms x 4z*/d2

=9.9757e11 x39.2262/1.7551e15

check with mod factor... 1.7551e15+ rt ( 9.95162e23/1000 x 35786000)/39.2262


1.7551e15+912298412=1.7551e15 (after checking for WEP/SEP... no change)

Fg= 22.3kgF    218.64N    0.21864N/kg


Nm equation with the new 'z'* and 1000kg...

9.9757e11 x 1000 x 39.47842/1.7551e15

for 1000kg it is 22.438kgF     220.05N compared to 221.56N from the CF equation.) 0.22N/kg This is a statistical match between the Nm and CF equation results.


However--- by the big G equation...

Fg =G m1.m2/d2

=6.67384e-11 x 5.9736e24 x1000/1.7551e15

=227.1485N 0.2271/kg

(surprised?.. a much greater deviation. Big G isn't looking all that accurate compared to the new Nm equation)  

Comparison table... 

CF---           221.56N

Nm---                    220.05N

Big G---      227.15N Big G is not very accurate at this geostationary orbit altitude.

Big G is a fudge used by Newton to get the right results. Refer to the G-less gravity equation--- and the gravity formula proof tab.
