A reaction force is a force which acts in the opposite direction to an applied force.

Newton's Third Law states that "whenever two objects interact, the forces they exert on each other are equal in magnitude and opposite in direction".

The terms 'action force' and 'reaction force' may sometimes be misleading as forces always act in pairs.

 ===Meaning===
-A '''reaction force''' is a [[force]] which acts in the opposite direction to an applied [[force]], following [[Newton's Third Law]].
+A '''reaction force''' is a [[force]] which acts in the opposite direction to an applied [[force]].
 ===About Reaction Force===
-: [[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".
+: [[Newton's Third Law]] states that "whenever two objects interact, the [[force]]s they exert on each other are equal in [[magnitude]] and opposite in direction".
 : The terms '[[Action Force|action force]]' and '[[Reaction Force|reaction force]]' may sometimes be misleading as [[force]]s always act in [[Force Pair|pairs]].
-: If [[weight]] is considered to be the [[Action Force|action force]] then the [[Normal Contact Force|normal contact force]] of an [[object]] on the ground can be considered the [[Reaction Force|reaction force]].
-: If there were no [[weight]] the [[object]] would not stay in contact with the ground so the [[Reaction Force|reaction force]] would not longer exist without the [[Action Force|action force]].
