Artificial Gravity ```Name: Tatenda Status: student Age: 20s Location: N/A Country: N/A Date: 1999 ``` Question: I need a full response to what exactly is "artificial gravity?" Replies: The term, at least as far as I am concerned, is due to centripal forces. If a pilot turns his get quickly into a turn, then the acceleration is the velocity (squared) divided by the radius of the turn. The smaller the radius the larger the acceleration of g forces, correspondingly the larger the velocity then the larger the g forces. That's it in a nutshell. H. Myron To get gravity, you need a mass to generate it, like the Earth. Suppose you could generate it some other way, with a big machine sporting zapping coils, ozone, a hunchbacked lab assistant and a half-dressed nubile mad scientist's daughter. That would be artificial gravity in the most usual sense of the world. Is this possible? Sure. Gravity is simply the distortion in space-time produced by a local concentration of energy. Any energy focussed in one spot will produce gravity. Of course, the amount of energy human beings are practically capable of focussing in one spot is trivial compared to the amount of energy represented by even a small piece of matter (via E = mc^2). As in the case of artificial intelligence, it remains so far much easier to generate the natural version. A less sweeping meaning of the phrase would be any mechanism that produces a feeling of downward force without visible downward motion. In this interpretation, it is easier to make artificial gravity. A closed elevator or airplane, or a roller coaster ridden with the eyes shut, when accelerating up will give the occupant a sense of artificial gravity, briefly. Riding in a spinning carnival ride or space station will give one the sensation of artificial gravity indefinitely. Grayce If it feels like gravity, then nobody can tell the difference. If you are on a merry-go-round, spinning around, it seems like "something" is pulling you out, away fromthe center of the wheel. This is the same effect as if there were more gravity pulling you out. So any force that pulls you down to the floor, just like gravity, can be called artificial gravity. Ross Click here to return to the Physics Archives
