Ok, let me explain the difference.

Open source software, does not specify any freedoms by definition.   
An OSS project can have a license that restricts what you do with  
that source code.  This is *not* Free.  Open source only imposes that  
the project should have source publicly available.  Open source is a  
development model.

Free Software, specifies Freedom that comes with the source code.  It  
does not specify that the source code be *publicly* available.  You  
can choose to only distribute for a fee.  Free Software is a philosophy.

In general *most* Free Software projects are Open source, and many  
Open source projects are Free.  But this is not inherently linked.
OSS, but not Free:  Qt under the old license before QPL
