Weightlessness

</dt>
1. A condition in which no acceleration, whether of gravity or other force, can be detected by an observer within the system in question. </dd>
Any object failing freely in a vacuum is weightless, thus an unaccelerated satellite orbiting the earth is weightless although gravity affects its orbit. Weightlessness can be produced within the atmosphere in aircraft flying a parabolic flightpath. </dd>
2. A condition in which gravitational and other external forces acting on a body produce no stress, either internal or external, in the body. </dd>
