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 aeroplane
s, 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.
