 Figure 3.13 shows a particle of mass $m$ in motion with respect to an inertial frame $\mathcal{F}^{I}=[\mathbf{O},\mathcal{T}=(\bar{\iota}_{1},\bar{\iota}_{2},\bar{\iota}_{3})]$ . The inertial velocity vector of the particle is denoted $\underline{v}$ . The linear momentum vector of a particle is defined as the product of its mass by its inertial velocity vector  
-图 3.13 示出了质量为 $m$ 的一个粒子相对于惯性系 $\mathcal{F}^{I}=[\mathbf{O},\mathcal{T}=(\bar{\iota}_{1},\bar{\iota}_{2},\bar{\iota}_{3})]$ 的运动。该粒子的惯性速度矢量记作 $\underline{v}$。粒子的线性动量矢量定义为其质量与惯性速度矢量的乘积。
