how does artificial gravity work?

Question

thanks

ok dont say google it, any1 and every1 really could google every single one of their questions and get answers.

Answer 1

Actual gravity generators don't work according to all the physics we know.

The suggested way of getting the illusion of gravity on board a spaceship or space station is to spin it. The momentum of objects on the inside of the outer edge will try to keep them going in a tangent to their circle of rotation, but they are constantly being stopped by the normal (passive) force of the hull of the ship, so the result is that to the people inside the outer edge of the ship feel what seems to be gravity. However, this gravity would work in some slightly unusual ways, for example you would be able to look along the hull of the ship and see the angle at which people are standing leaning more towards you the farther away they are, and if you went closer to the axis of rotation the effective gravity would drop quite quickly until it hit zero at the axis of rotation.

Answer 2

If you saw "Space Odyssey 2001" the film, you may have noticed the space station from which the shot towards Jupiter was launched was little more than a giant rotating wheel.

That wheel's rotation created the gravitational effect through centripetal/centrifugal force. This force is equal to C = mv^2/R [See source.]; where m is the mass of each space person, v is the tangential velocity of that person on the rim of the station some R radius away from the center of the spin.

The spinning space station wants to throw the space farers outward, away from the center of the spin. It want to do this because things in motion want to travel in a straight line. That tendency to fly outward is called centrifugal force even though many physicists do not recognize it as a true force.

The rim of the station's wheel pushes back against the soles of the inhabitants to keep them from flying out. That's centripetal force.

Centrifugal and centripetal forces are equal in magnitude and opposite in direction...always. As a consequence, the space people have a net force of zero acting on them as they walk around the rim. Therefore, they do not accelerate outward or inward. Any way, the force on the soles of their shoes (or bare feet) and pushing them in the direction of the center of the spin is the so-called artificial gravity.

To have an artificial weight equal to weight on Earth, but due to that artificial gravity, we'd solve a = g = v^2/R = 9.81 m/sec^2, which is called 1 gee. You know the radius of the station; so you can solve for v to find out how fast the station needs to spin for that 1 gee = 9.81 m/sec^2 acceleration due to the artificial gravity.

At 1 gee = g = 9.81 m/sec^2 on the space station, the girl's weight will be the same on the station as on the Earth. This results because her weight is W = mg on Earth and in the space station no matter what the source of g = 9.81 m/sec^2 might be.

I should mention the so-called graviton. This is a speculated messenger particle that flies out from mass, grabs another mass, and hauls it in. We see that result as the force of gravity.

But gravitons are no more than scifi at this point. Some very way out models (like string/M theory) posit their existance, but no one has ever seen or masured one.

However, if there is a graviton, highly speculative, there might also be an antigraviton. If there were, and we could harness it, we could neutralize the gravitons and, therefore, end up with zero gravity. Imagine how easy it would be to launch a space ship in zero gravity conditions. The ship would have no weight because W = mg = m0 = 0.

Answer 3

Albert Einstein confirmed that gravity and acceleration are the same stress. The result's the same while you're status on the outdoors of the Earth, or are in a spaceship continuously accelerating at 1g. considering which you may improve up continuously with out reaching the fee of sunshine, you may generate gravity for as long as you elect it, provided you may holiday in a immediately line and have sufficient means to maintain accelerating. you additionally can simulate gravity via centripetal stress, spinning a craft some proper axis, yet this introduces Coriolis outcomes, and make shifting products holiday in curved paths. you may atone for those outcomes, in spite of the undeniable fact that, and spinning could be a pragmatic replace for acceleration. Anti-gravity will probably exist basically interior the technology fiction realm. considering that gravity is an important stress, like the electrical powered, vulnerable and robust forces, it probably has a stress provider, like the photon, w or z particle. The latter 3 have not have been given any anti particle, so this is logical to think of gravity does not the two. as an occasion, there's no anti-photon. To have anti-gravity, we'd choose an "anti-graviton." certainly one of those element is rather probably to no longer exist.

Answer 4

1) force on organs. Our organs are used to the feeling of gravity acting on them. Artificial gravity basically simulates the effect by rotating someone in a large cylinder; their body tends to go outward, following their bodies' inertial path, which is what feels like gravity. The organs experience this force outward as well, so they feel the effect of artificial gravity.
2) objects thrown travel same path. For example, if you throw a ball up into the air, once the ball leaves your hand, it will follow a tangential inertial path, and will basically land at your feet b/c you will have rotated to where the ball lands. In other words, when you throw a ball "up" (as you see it in the cylinder) it comes down at you rfeet, but what's really happening here is that objects follow natural inertial paths outward and tangentially.
To summarize:
-organs feel as though they're acted on by gravity
-object (ball) thrown upward will land at feet.

Answer 6

the earths force of gravity is simulated to cause a gravitional pull, eg in space , if a space stn wanted gravity, they would have to rotate it at a specific speed to cause centrifugal force (pulling force) which would cause artificial gravity for the objects within.

Answer 7

Two words: Centripital force.
