动能
物体或系统因其运动而具有的能量。
- 非旋转物体的动能为 —
\begin{align} \label{eq:13101a} KE = \small\frac{1}{2} \normalsize \, m \, \dot{u}^2 \end{align}
式中 —
| \( KE \) | = 动能 |
| \( m \) | = 质量 |
| \( \dot{u} \) | = 速度 |
- 电感器的动能为 —
\begin{align} \label{eq:13102a} KE = \small\frac{1}{2} \normalsize \, L \, i^2 \end{align}
式中 —
| \( KE \) | = 动能 |
| \( L \) | = 电感 |
| \( i \) | = 电流 |

Kinetic energy
The energy of an object or system that is associated with its motion.
- The kinetic energy of a non-rotating object is —
\begin{align} \label{eq:13101a} KE = \small\frac{1}{2} \normalsize \, m \, \dot{u}^2 \end{align}
where —
| \( KE \) | = kinetic energy |
| \( m \) | = mass |
| \( \dot{u} \) | = velocity |
- The kinetic energy of an inductor is —
\begin{align} \label{eq:13102a} KE = \small\frac{1}{2} \normalsize \, L \, i^2 \end{align}
where —
| \( KE \) | = kinetic energy |
| \( L \) | = inductance |
| \( i \) | = current |
