Watch the No Tears: Rhythm 1 online guitar lesson by Andy Aledort from Jam Night Vol. 2

I begin with hammer-ons into C/E played in fifth position on the inside four strings, and then slide back to a standard G major triad shape, followed by a slide up two frets for Am followed by the simple addition of an F note to the Am triad--A-C-E--to switch to A-C-F, the notes of the F major triad.
