Newton's Third Law

January 6, 2007 4:38am CST
I'm kinda confused here. Newton's third law states that every action has a equal and opposite reaction. Wouldn't the opposite reaction meet another opposite reaction,which has a opposite reaction and so on and so forth. Wouldn't this lead to everything being in equalibarium,causing everything to be unable to move?

The law does not say that the action and reaction act on the same object. The conservation of momentum (in a non relatavistic universe) is an example of this. Momentum is conserved but can be transferred from one object to another (by an action/reaction type event). Which part is action and which reaction is purely a matter of convention ... the labels can be applied either way round.
