Get a hula hoop attach a camera to it. Drop hula hoop over something with it being in the middle. Did thing in hula hoop take off? No. Thing had no momentum. It’s velocity versus relative velocity.

You need to cut the hula hoop in half. The bottom moves and the top is stationary off to the side. The cube pops out at the same speed the bottom half is falling, but because the top half of the hula is stationary, the cube seems like it’s moving upwards.
