==Key Stage 4==
===Meaning===
'''Newton's Third Law''' states that "For every [[Action Force|action force]] there is a [[Reaction Force|reaction force]] with an equal [[magnitude]] but acting in the opposite direction.

===About Newton's Third Law===
: The two [[force]]s referred to in '''Newton's Third Law''' are on separate [[object]]s which are interacting.
: 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 two [[force]]s will be equal in [[magnitude]] and opposite in direction.
: The terms [[Action Force|"action force"]] and [[Reaction Force|"reaction force"]] may be misleading as they simply refer to which [[object]] the observer was interested in first, eg Did the ball hit the head or did the head hit the ball?
