: The two [[force]]s in a '''force pair''' may be referred to as an [[Action Force|action force]] and a [[Reaction Force|reaction force]].
: When an [[object]] "A" exerts a [[force]] ([[Action Force|action force]]) on [[object]] "B" then [[object]] "B" will exert a [[force]] ([[Reaction Force|reaction force]]) on [[object]] "A". These are a '''force pair''' which will be equal in [[magnitude]] and opposite in direction to one another.
