When astronauts sleep in space, they sleep in small cabins or in sleeping bags that are attached to the wall of the station.Which condition requires them to attach their sleeping bags to the wall?

In orbit, the station and its astronauts are in free fall around Earth, so objects inside float rather than resting on a floor. Attaching a sleeping bag to the wall keeps it and the astronaut from drifting around while they sleep. The correct choice is free fall.
