In some media it is equal to the drift velocity over the mobility, and for a moving point particle it has velocity field and acceleration field terms.
The de Hoffman-Teller frame can be found by a transformation setting this quantity to zero upstream and downstream of a shock. In some media it is equal to the drift velocity over the mobility, and for a moving point particle it has velocity field and acceleration field terms. A generalized form of Ohm's law relates it to the conductivity tensor and the current density. Poisson related its Laplacian to the charge density, and its surface integral is related to enclosed charge in Gauss's law. For 10 points, name this quantity which is proportional when static to the source charge over the distance squared, according to Coulomb's law.
