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
