Talk:Theoretical gravity

Where does this article fit in?
The content of this article is a subset of Gravity of Earth and there is also a lot of overlap in subject matter between this article and gravity anomaly, free-air anomaly and Bouguer anomaly. Also, the title is vague. It could refer to any of the types of gravity anomaly or even General relativity. So my questions are – what purpose is this article serving, and what should it be called?

My suggestion: rename this article to something like Reference gravity formula or International gravity formula, consistent with the focus on world gravity models. Put most of the material in Gravity of Earth here, leaving a more accessible summary in that section. To make this article readable, there needs to be more detail on how the terms in the formulae are derived. RockMagnetist (talk) 05:53, 30 October 2011 (UTC)


 * Sounds good - could rename to IGF. Also useful to explain formula based on shape and centripetal force due to rotation and indicate relative size of the 2 effects ? shows effect of rotation. - Rod57 (talk) 10:20, 8 September 2014 (UTC)

Meaning of the sin2 coefficient
This sentence does not seems completely correct since ~65% of the effect is due to Earth rotation. As a physically defined form parameter it corresponds to the geometrical flattening f of the earth ellipsoid. — Preceding unsigned comment added by 2.230.128.127 (talk) 11:17, 4 April 2014 (UTC)
