Guest onstage Posted April 23, 2004 Share Posted April 23, 2004 is it possable to make the gravity on a person more than it is normaly to simulate gravity on another world Free For All Link to comment Share on other sites More sharing options...
jordan Posted April 23, 2004 Share Posted April 23, 2004 Certainly. Gravity and acceleration are indistinguishable for us. Elvevators (fast ones) are a good example. As the floor gets pulled up under us, we feel like we are slightly heavier. For astronauts, simulation of take-off sized acceleration can be produced in a centrifuge. This is a chamber in which a human sits as it spins around faster and faster. Just like the elevator (only a much greater scale) the person finds increased difficulty in moving. This effect is measured in g's or number of times the gravity is greater than that of the earth. Space is considered to be esentialy a "zero-g" environment. Earth is 1 g and so on. Hope this helps.

AntiMagicMan Posted April 23, 2004 Share Posted April 23, 2004 It is also possible to make it less than normal by going into free fall. Nasa trains astronauts by making a specially modified 747 go into a nose dive for a short period of time, normally about a minute. Link to comment Share on other sites More sharing options...

swansont Posted April 23, 2004 Share Posted April 23, 2004 Space is considered to be esentialy a "zero-g" environment. Earth is 1 g and so on. Deep space is zero-g. Near earth orbit is microgravity only because you are in orbit - there is still significant gravity present. You just feel weightless because you are in perpetual freefall. If you weren't in orbit, but in space near a planet, you'd feel gravity's pull. Link to comment Share on other sites More sharing options...
Guest onstage Posted April 24, 2004 Share Posted April 24, 2004 well true, but i was wondering if they could make that enviroment where someone could stay in it for a long period 30 days at something like 1.5 -g Link to comment Share on other sites More sharing options...
Crash Posted April 24, 2004 Share Posted April 24, 2004 One extremely long elevator, Is that a minus in front of teh "g", cant have negative gravity, you mean 1.5g? send them to saturn for a month to live Link to comment Share on other sites More sharing options...

jordan Posted April 24, 2004 Share Posted April 24, 2004 Although a valid answer, I don't know of anyone who would want to live in a centrifuge for 30 days. You'd be quite dizzy. Link to comment Share on other sites More sharing options...
admiral_ju00 Posted April 24, 2004 Share Posted April 24, 2004 a nice new shiny coaster will have a similar effect plus it'll be a lot more fun than an elevator. well, most elevators. damn do i miss those high-speed elevators the WTC had Link to comment Share on other sites More sharing options...
