Consider a material particle P described by its rest mass $m$ and momentum $p$. Definition: the kinetic energy of P is the number

\begin{align} K \equiv \frac{\, p^{ 2}}{2m} \end{align}

Since $m > 0$ for material particles, the kinetic energy is never negative. And in an inertial frame of reference, the momentum is directly proportional to the wavenumber $\, \kappa \,$ so that $K$ is proportional to $\kappa ^{2}$. Then recall that the wavenumber depends only on the coefficients of dynamic quarks. So overall, the kinetic energy is a description of P's dynamic quark content as compared to the mass.

Sensory interpretation: dynamic quarks and the wavenumber have already been interpreted as representations of visual perceptions. And, the mass of a heavy particle can be understood as a descriptor of thermal sensations. So in an ideal frame of reference, the kinetic energy characterizes the sensory magnitude of visual sensations in a ratio to thermal sensations.
 Next step: potential energy.
