Zero-G: "Movement in Microgravity: Skylab to Space Shuttle" 1988 NASA Weightlessness Footage
more at scitech.quickfound.net "This video takes a serious and humorous look at life in the low gravity environment of space flight. The video also includes onboard activities from Skylab to Space Shuttle missions. " Public domain film from NASA, slightly cropped to remove uneven edges, with the aspect ratio corrected, and mild video noise reduction applied. en.wikipedia.org Weightlessness (or zero-g) is the condition that exists for an object or person when they experience little or no acceleration except the acceleration that defines their inertial trajectory, or the trajectory of pure free-fall. The physical path of an inertial trajectory depends only on the direction and strength of the sum of the gravitational attractions outside of the inertial reference frame. Accelerations that are not due to gravity are called "proper accelerations" and it is only these forces (such as a push from a floor or seat) that cause g-forces. Weight is the product of mass and the g-force acceleration. Weightlessness is therefore always produced by the absence of g-forces. Accelerometers, which can measure only accelerations that produce g-force and weight, cannot detect acceleration in weightless conditions, including free fall. The definition and use of #39;weightlessness #39; is difficult unless it is understood that the sensation of "weight" is only indirectly produced by gravity, and results not from gravitation acting alone (which is not felt), but instead by the mechanical forces that ...From:webdev17Views:58 6ratingsTime:08:41More inScience Technology
