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
