"Effective Mass" is used in the motional equation for electrons in solid state bodies, depending on the wavenumber and corresponding to its velocity and energy level.

$m^* = \hbar^2k(\frac{d\varepsilon}{dk})$, where $\hbar$ is the reduced Planck constant, $k$ is the wavenumber, and $\varepsilon$ is the energy of the electron.
