        Mass vs. Weight: Stretching Mass

        In this video, an astronaut on board the International Space Station demonstrates weightlessness by comparing two water bags tethered to a line by stretchable bands. Despite the fact that the two bags have very different masses (one is full; one is empty) neither experiences a gravitational force, as evidenced by the lack of "stretch" in the connecting tethers.

        This media asset is from the Mass vs. Weight series produced by the Teaching From Space Office at NASA's Johnson Space Center.
