You can either launch NPC's forwards with great force, or knock them high into the air.
Here's two very short videos showing it in action:

If you want to try something related, you can try a combo using either shield bash or unrelenting force, then use something like a spell that applies force to launch them while they are mid-air ragdolls. I haven't tried it. This could possibly launch things to the damn moons.
