Voimakentän

Voimakentän is the genitive form of voimakenttä, Finnish for “force field.” In Finnish, voimakenttä denotes a region of space in which a force acts on matter or energy, and voimakentän is used to express possession or relation, as in voimakentän vaikutus (the effect of the force field) or voimakentän voimakkuus (the strength of the force field).

In physics, a force field is a physical quantity defined at every point in space and time that can exert forces on objects. Common examples are gravitational, electric, and magnetic fields. Fields are described by field equations: Newton’s law for gravity, Maxwell’s equations for electromagnetism; more generally, quantum field theory treats particles as excitations of underlying fields and interactions as exchanges of gauge bosons.

In Finnish usage, voimakenttä can refer to real physical fields and to conceptually modeled energy barriers or protective barriers found in science fiction and popular science. The genitive form voimakentän appears in phrases such as voimakentän tiheys, voimakentän suunnittelu, or voimakentän vaikutus.

Etymology: voimakenttä is a compound of voima “power, force” and kenttä “field”; the genitive form is voimakentän.
