The floor does not move so your body has to absorb the shock of having to suddenly stop.

Nothing is reliable; even the floors move up and down.

That was the moment the floor moved in a really big way.

He got to his feet and immediately fell down again as the floor moved beneath him.

The floor in my room was moving as the gusts came through.

The floor had moved slightly, she had been certain of that.

Suddenly, the floor moved out from under him and he was thrown backward.

At this point, both the floor and the room are slowly moving in unison.
