Fsus2 is F, G and C — F with the third replaced by the second.
It sounds open, and neither major nor minor. With no third it works over either quality, which is why strummed parts lean on it.

| F | G | C |
|---|---|---|
| 1 | 2 | 5 |
Suspended — it hangs until something moves.
Also written F2 or F suspended 2nd. The same chord either way; which spelling you meet depends on who wrote the chart.
Fsus2 in 2nd in bass puts G in the bass instead of F, the 2nd of the chord. The notes are the same; what changes is what the bass line does, which is most of why you would reach for it — it lets the lowest voice move by step where the root would have jumped.
2 of Fsus2’s 8 common shapes do this: xx5568, x-10-10-10-13-13.
Start with xx3563 — no barre and low, at the 3rd fret. None of the shapes for Fsus2 uses an open string, so every one of them is movable; the lowest sits at the 1st fret. 4 of the 8 need a barre. Together they cover the neck from the 1st fret to the 13th.
