For a particle of constant invariant mass ''m'' > 0, $\backslash mathbf\; =\; m\backslash mathbf\; \backslash ,$ where $\backslash mathbf=\backslash gamma(c,\backslash mathbf)\; \backslash ,$ is the four-velocity, so we can relate the four-force with the four-acceleration $\backslash mathbf$as in Newton's second law: :$\backslash mathbf\; =\; m\backslash mathbf\; =\; \backslash left(\backslash gamma\; \backslash over\; c\},\backslash gamma\backslash right)$. Here :$=\; \backslash left(\backslash gamma\; m\; \backslash right)=$ and :$\}=\; \backslash left(\backslash gamma\; mc^2\; \backslash right)=$. where $\backslash mathbf$, $\backslash mathbf$ and $\backslash mathbf$ are 3-vectors describing the velocity and the momentum of the particle and the force acting on it respectively. 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「Four-force」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.
