Mmm, that kind of gives the wrong idea, since you can just as easily play a digital synth by pressing keys and playing it like a piano. Also, a few analog synths do have really basic sequencers, so on some of them you can just "push buttons" for playback.
A good definition of "analog" in the context of instruments might be that the sound is made by some kind of continuously variable physical force -- whether that's the electricity used in an analog synth or electric guitar + amp, or the mechanical force of striking a piano or blowing into a flute -- rather than a quantized mathematical calculation as in a digital synth.
The "acoustic" / "electric" thing is really a different axis of description, basically just referring to whether the instrument has to be "plugged in" to make the desired sound. All acoustic instruments are analog, but you can also have electric (non-acoustic) instruments that are still very much analog, like an electric guitar.

Technically you'd call them "electric" as opposed to "electronic" but really, it gets quite blurry as to categories.
