I have always sworn that the only way I will ever get married is if I can do it in microgravity..
Any object in
freefall experiences microgravity conditions, which occur when the object falls toward the
Earth with an acceleration equal to that due to
gravity alone (approximately 9.8 meters per second squared
m/s2, or 1 g at Earth's surface). Brief periods of microgravity, or µg, can be achieved on
Earth by dropping objects from tall structures. Longer periods are created through the use of
aeroplanes,
rockets, and
spacecraft. The microgravity environment associated with the
space shuttle is a result of being in
orbit, which is a state of continuous freefall around the Earth. A circular orbit results when the
centripetal acceleration of uniform circular motion (v2/r; v = velocity of the object, r= distance from the centre of the object to the center of the Earth) is the same as that due to gravity alone.
thankyou, NASA
