Answers.Text: It's not a direct sacrifice perhaps, but since Chess is all about working a couple of steps ahead I don't see a reason why it wouldn't count as a sacrifice. Honestly I don't know where it's defined.

  The opening you are after is Damiano Defense: `1.e5 e4 2.Nf3 f6`.
  
  Note that after `3. Nxf3 fe?` is a mistake, `3...Qe7` keeps the material equal. There is no way to take the knight and save the rook as far as I know.

  The knight is not sacrificed. If black takes it then he will regret it. The best is to lose the rook and have a bad position.
  
  To answer the other half of your question: Ke7 saves the rook but leads to a terrible position.
  
  After QxP+, black has to play Kf7, then white moves Bc4+. It's all downhill from there until Black is mated.
