加速度（惯性）力
由加速运动的质量（即速度正在变化的质量）所产生的力 —
\begin{align} \label{eq:13001a} F = m \, \ddot{u} \end{align}
其中 —
| \( F \) | = 力 |
| \( m \) | = 质量 |
| \( \ddot{u} \) | = 质量的加速度 |
Acceleration (inertial) force
A force that results from an accelerating mass (i.e., a mass whose velocity is changing) —
\begin{align} \label{eq:13001a} F = m \, \ddot{u} \end{align}
where —
| \( F \) | = force |
| \( m \) | = mass |
| \( \ddot{u} \) | = acceleration of the mass |
