Owing to its northerly position a large part of Ungava is treeless, and belongs to the barren grounds where caribou roam and feed on the socalled caribou moss, a greyish lichen. The caribou, moose, antelope, mountain sheep, beaver, otter and mink are scarce.
Espionage normally is not reconnaissance, because reconnaissance is a military force's operating ahead of its main forces; spies are non-combatants operating behind enemy lines. Often called  recce  (British and Canadian English) or  recon  (American and Australian English), the associated verb is reconnoitre.
In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. It is measured in the SI unit of newtons and represented by the symbol F. The original form of Newton's second law states that the net force acting upon an object is equal to the rate at which its momentum changes with time.
