What is the difference between "section" and "part"?  

The Longman Dictionary of Contemporary English says for "section":  


  one of the parts that something such as an object or place is divided into


and says for "part":  


  a piece or feature of something such as an object, area, event, or period of time


I know that "section" is smaller than "part" in size, but I'm totally confused about their usage in sentences. For example, is "the front section of the car was damaged" correct grammatically? Or is "in sections of Canada, French is the first language"  correct?
