In SI units, it is measured in radians per second squared (rad/s), and is usually denoted by the Greek letter alpha (''α''). == Mathematical definition == The angular acceleration can be defined as either: :$=\; \backslash frac\; =\; \backslash frac$ , or :$=\; \backslash frac$ , where $$ is the angular velocity, $a\_T$ is the linear tangential acceleration, and $r$, (usually defined as the radius of the circular path of which a point moving along), is the distance from the origin of the coordinate system that defines $\backslash theta$ and $\backslash omega$ to the point of interest. 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「Angular acceleration」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.
