In physics, a force field is a vector field corresponding with a non-contact force acting on a particle at various positions in space. Specifically, a force field is a vector field F {\displaystyle \mathbf {F} } , where F ( r ) {\displaystyle \mathbf {F} (\mathbf {r} )} is the force that a particle would feel if it were at the position r ...
A field force in British, Indian Army and Tanzanian military parlance is a combined arms land force operating under actual or assumed combat circumstances, [1] usually for the length of a specific military campaign. It is used by other nations, but can have a different meaning.
A field has a consistent tensorial character wherever it is defined: i.e. a field cannot be a scalar field somewhere and a vector field somewhere else. For example, the Newtonian gravitational field is a vector field: specifying its value at a point in spacetime requires three numbers, the components of the gravitational field vector at that point.
In physics, a unified field theory (UFT) is a type of field theory that allows all fundamental forces and elementary particles to be written in terms of a single type of field. According to modern discoveries in physics, forces are not transmitted directly between interacting objects but instead are described and interpreted by intermediary ...
What Air Force leadership says is needed for future fights "China is doing everything it can to exploit the opportunities that emerging technologies are providing to field forces designed to ...
Army Ground Forces survived the post-war reorganization of the War Department. It became Army Field Forces in 1948, Continental Army Command (CONARC) in 1955, and was ultimately divided into United States Army Forces Command (FORSCOM) and United States Army Training and Doctrine Command (TRADOC) in 1973.
It was created on 1 July 1973 from the former Continental Army Command, which in turn supplanted Army Field Forces and Army Ground Forces. The command has formations and units located at 15 installations, including the National Training Center at Fort Irwin, California and the Joint Readiness Training Center at Fort Johnson, Louisiana (the ...
The strong interaction, or strong nuclear force, is the most complicated interaction, mainly because of the way it varies with distance. The nuclear force is powerfully attractive between nucleons at distances of about 1 femtometre (fm, or 10 −15 metres), but it rapidly decreases to insignificance at distances beyond about 2.5 fm. At ...
