What is the difference between capitalism and the free market?

Google definitions:<p>Capitalism: An economic and political system in which a country's trade and industry are controlled by private owners for profit.<p>Free market: An economic system in which prices are determined by unrestricted competition between privately owned businesses.<p>Those sound like the same thing? Why do we have two separate words for them? Can free market exist without capitalism or vice versa?<p>I have yet to get an answer without circular logic on this.
