The floor tilted and his stomach lurched into his throat.

The floor lurched, as if the ship had accelerated.

The floors lurched and he grabbed onto the ladder.

The floor lurched gently underfoot; the old man didn't appear to notice.

The floor lurched, slamming them against each other, and air flooded in, blessedly cool.

They felt the floor lurch beneath their feet, and a little weight was granted them as the space-ship got under way.

The whole ship began to shake, and the floor lurched under their feet.

The floor lurched into his body, snatching his breath away.

The floor lurched again and she slipped, going down on both knees.
