 |  |  |  |  The condition of microgravity comes about whenever an object is in "free fall": that is, it falls faster and faster, accelerating with exactly the acceleration due to gravity (1g). If an object is traveling fast enough, it can be in a continuous free-fall which we call "orbit." Objects in a state of free-fall or orbit are said to be "weightless" because their mass would register "0" on a scale.
