Using only three strings would be a power chord.

There are simplified versions of barre chords which have a barre that covers 5, 4, or 3 strings (or 2, if you want to count the simplified F). They're usually just to get people used to pressing down on more than one string. As for the "why acoustic?" inquiry, probably because strings on an acoustic are a lot harder to push down on, especially if you learned on an electric.

So there!
