There are several types of sentences:
  • Simple or Declarative Sentence.
  • Command or Imperative Sentence.
  • Question or Interrogative Sentence.
  • Exclamatory Sentence.

For example, you first sentence is actually a question, so you need to put the verb DO in the beginning:
Why DO we use .... ?

On the other hand, "I want to know WHERE my son IS" is a declarative sentence, not a question, so it would be wrong to say "I want to know WHERE IS my son". You can put "IS" up front if you rewrite it as a direct speech question, for example - He said "Where IS my son?".
