==Key Stage 4==
===Meaning===
A '''reaction force''' is a [[force]] which acts in the opposite direction to an applied [[force]], following [[Newton's Third Law]].
===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".
: 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]].
