Expressed as an equation, rotatum Ρ is: :$\backslash vec\; P\; =\; \backslash frac$ where τ is torque and $\backslash fract\}$ is the derivative with respect to time $t$. The term ''rotatum'' is not universally recognized but is commonly used. this word derived from Latin word ''rotātus'' meaning to rotate. The units of rotatum are force times distance per time, or equivalently, mass times length squared per time cubed; in the SI unit system this is kilogram metre squared per second cubed (kg·m2/s3), or Newtons times meter per second (N·m/s). ==Relation to other physical quantities== Newton's second law for angular motion says that: :$\backslash mathbf=\backslash frac\}$ where L is angular momentum, so if we combine the above two equations: :$\backslash mathbf=\backslash frac\}=\backslash fract\}\backslash left(\backslash frac\}\backslash right)=\backslash frac\}=\backslash frac)\}$ where $I$ is moment of Inertia and $\backslash omega$ is angular velocity. If the moment of inertia isn't changing over time (i.e. it's constant), then: :$\backslash mathbf=I\backslash frac$ which can also be written as: :$\backslash mathbf=I\backslash zeta$ where ς is Angular jerk. 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「Rotatum」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.
