electric displacement vector
11electric dipole — Pair of equal and opposite electric charges, the centres of which do not coincide. An atom in which the centre of the negative cloud of electrons has been shifted slightly away from the nucleus by an external electric field is an induced electric …
12Poynting vector — In physics, the Poynting vector can be thought of as representing the energy flux (in W/m2) of an electromagnetic field. It is named after its inventor John Henry Poynting. Oliver Heaviside independently co discovered the Poynting vector. In… …
13Euclidean vector — This article is about the vectors mainly used in physics and engineering to represent directed quantities. For mathematical vectors in general, see Vector (mathematics and physics). For other uses, see vector. Illustration of a vector …
14Flux — This article is about the concept of flux in science and mathematics. For other uses of the word, see Flux (disambiguation). In the various subfields of physics, there exist two common usages of the term flux, both with rigorous mathematical… …
15Index ellipsoid — In optics, an index ellipsoid is a diagram of an ellipsoid that depicts the orientation and relative magnitude of refractive indices in a crystal. The equation for the ellipsoid is constructed using the electric displacement vector D and the… …

18Ampère's circuital law — Ampère s law redirects here. For the law describing forces between current carrying wires, see Ampère s force law. Electromagnetism …
19Defining equation (physics) — For common nomenclature of base quantities used in this article, see Physical quantity. For 4 vector modifications used in relativity, see Four vector. Very often defining equations are in the form of a constitutive equation, since parameters of… …
20solids, mechanics of — ▪ physics Introduction science concerned with the stressing (stress), deformation (deformation and flow), and failure of solid materials and structures. What, then, is a solid? Any material, fluid or solid, can support normal forces.… …
