翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Moment of inertia factor ： ウィキペディア英語版 Moment of inertia factor In planetary sciences, the moment of inertia factor or normalized polar moment of inertia is an important dimensionless quantity that characterizes the radial distribution of mass inside a planet or satellite. ==Definition== For a planetary body with principal moments of inertia ''A:$\backslash frac$, where ''C'' is the polar moment of inertia of the body, ''M'' is the mass of the body, and ''R'' is the mean radius of the body. For a sphere with uniform density, ''C/MR2'' = 0.4. For a differentiated planet or satellite, where there is an increase of density with depth, ''C/MR2'' < 0.4. The quantity is a useful indicator of the presence and extent of a planetary core, because a greater departure from the uniform-density value of 0.4 conveys a greater degree of concentration of dense materials towards the center. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Moment of inertia factor」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
