force field

…an example of a central force field that is far from inverse square in character.

…electromagnetic, and other fields of force the aim of finding the most economical basis from which, in principle, theories of all other material processes may be derived. Some of these processes are simple—a single particle moving in a given field of force, for example—if the term refers to the nature…

…propagate, the possibility exists for force fields to act at large distances from the point where they originated.
