Artificial gravity Definition and 68 Threads

Movement isn't required to achieve gravity, even the artificial kind. Standing on a rotating body requires you to be actually physically standing on it. How is this achieved? Well, by gravity of course. Unless you are tied/stuck to the rotating body, but in that case there is no gravity pushing...

For all the attention we‘ve paid to ring habitats, we haven’t talked that much about the interior design of the central trunk yet, around which the rings rotate. Just having one big hollow ship trunk, about 100 metre in diameter, would be a lot of wasted space. It would also be too easy for...

The world building thread about a derelict spaceship got me wondering. An object can rotate on two axes simultaneously, yes? Is that stable in flat space? If so, what would occupants experience as gravity? Would it change over time?

I had a bit of a brainwave regarding artificial gravity (outside of rotation or linear acceleration). As we know "gravity plating" is just a plot device to allow sci-fi films and shows to escape the pain of having to accurately recreate a zero-g environment. But then I thought: gravity is a...

It's one of those staples of sci-fi. Unless you're going for a hard sci-fi that uses rotation or linear acceleration to achieve simulated gravity, your starship will likely use "gravity plating". As we all know, gravity plating is just a plot device, usually for shows with more limited budgets...

Space exploration plays an important role in expanding our human civilisation beyond earth. But the major challenge is our difficulty of working in zero gravity. So the only possible explanation I could think of is creating artificial gravity. How can this be done ?

Hi! I'm curious what your take on this is. I'm taking an introduction to U.S. Government course and my professor was discussing the inefficiencies of the public sector; the discussion on politics isn't relevant here but he did make an interesting point about space travel. He argued that the...

On the AG vein, had a thought/question re the work that it is doing, by work I mean joules. So, AG generator is on the ship, as are the occupants. So relative to the AG generator (assume for the time being no one is moving on the ship) the things the generator is acting on are not moving...

We get this type of question now and then, even in the main physics forums. One such question in the Sci Fi forum is from this one: https://www.physicsforums.com/threads/what-is-the-largest-possible-rotating-wheel-space-station.950770/ So I don't know of people have seen this video from a few...

It is often proposed that gravity could be simulated on a space station by rotating around an axis, such that the astronaut experiences the centripetal force of the space station wall, analogously to gravity. It is usually mentioned that the radius of rotation must be very large to avoid...

Consider a hollow sphere roughly the size of the moon, spun up to produce 1g of centripetal acceleration along a band at its equator (about 15000 kph) Big stuff, I know. I have a few questions about the implication of such a system, and I hope someone can help me find some answers! - How tall...

I know that rotation can cause there to be artificial gravity. But I was thinking of making a floor plan that is all horizontal with the generation ship having a rocket shape and with it being longer than it is wide and wider than it is tall. So I was thinking of giant centrifuges on every...

Homework Statement 1. Do research to find out what artificial gravity is and how it is related to centripetal motion. Explain how artificial gravity could be created in a weightless environment and give a reason why we would want to do this.Homework Equations None. The Attempt at a Solution...

I'd be extremely grateful if anyone could help me with this ... its mainly part iv) that I'm stuck on but the other parts build up to it! Thanks very much! 1. Homework Statement I have a wheel shaped space station of radius 100m rotating about its symmetry axis (defined to be the z axis) at...

Hey all, *this is my first post on this forum* I've read a lot about the different ways of artificial gravity on this forum, and we've discussed everything from realistic ideas that can be accomplished with today's tech, all the way to fictitious situations in sci fi books. BASICALLY, I would...

If a space station has artificial gravity created by spinning, how can it best be spun up to speed? Little attitude rockets could do it, but they would use up fuel, and limit your ability to change the spin rate in future. What if you had an external wheel that you spin up very fast in the...

When International Space Station is at rest, it revolves around it's axis once per orbital revolution (92.65 minutes). In other words, is tidally locked. Does the spinning around it's axis do create non-zero artificial gravity? Does it have non zero angular momentum?

How fluids would act around the circumference of a space centrifugal, where the habitable zones are. Given that we have a radial gradient of Artificial Gravity , plus Coriolis, inertia, frictions etc. Id expect some change. Will add a list of questions but this more like an open discussion...

Would a spinning space station as depicted below that use centrifugal force to create artificial gravity actually work? I'm thinking that it would not, this is because the centrifugal force would not affect an astronaut inside unless he was actually fastened mechanically to the hub. The fact...

Hello everyone, i m working on a full circle space centrifuge concept. I try to support it with some maths but i don't want to dive into crazy details. I used alrdy lot of countermeasures to dangerous effects.I have problems similar to bridge mechanics. The design is not solid so i need to be...

Homework Statement What must be the period of rotation of a spatial station so that artificial gravity in a cabin that is 45 m of radius from the axis of ration corresponds to gravitational field at the surface of Earth ? Homework Equations T=(2(pi)r)/v Sum of forces r prime = (mv^2)/r The...

Dear Experts, I believe that we use the concept of Pseudo Forces, to analyze mechanics within an accelerating frame of reference. Pseudo force seems to be a 'correction' in acceleration provided to all the points that are not riveted to the accelerating frame of reference. And centrifugal force...

Homework Statement One way to simulate gravity is to shape a spaceship like a cylindrical shell that rotates, with the astronauts walking on the inside surface. Explain how this simulates gravity. Homework Equations ## F = m/v^2 ## The Attempt at a Solution My textbook's solution guide...

Hi everyone, here's the situation: Everyone knows that you can simulate artificial gravity by rotating a space ship. Usually these scenarios include an atmosphere with regular air inside. I know that the inclusion of air has an influence on the effects inside by way of friction. How different...

How is this possible? The reason spinning a bucket of water upside down keeps the water inside the bucket is because you're applying force and accelerating the bucket. But in space, there is nothing 'accelerating' the rotation of a spacecraft , it is merely in continuous Newtonian motion...

I've been throwing around designs for a space station with artificial gravity for a while now and here is where its at in my head, the drawing is EXTREMELY crude but hopefully someone can understand the idea. the 2d drawing is meant to show a basic side view of it, the blue arrows indicating the...

The other day, I was learning about creating "artificial" gravity by building a gigantic circularly shaped ship which would revolve at a frequency such that the centripetal acceleration coincided with the acceleration due to gravity g (analogous to the shape and movement of earth). I can...

Hi As I'm sure we're all aware, there are many planned missions to Mars. Given its distance (some 3 years away given today's tech) by the time any humans make it there, their muscles would be completely useless on account of wastage as a result of no gravity. Therefore, artificial gravity is...

I hope this is the right place for this question. How would spinning a ship in space create artificial gravity? I've long wondered if it actually would, or if you'd just have people floating in a spinning ship. I did a minimum of searching and found that there have been actual proposals...

Every time I see a SF pic which has some simulated gravity by spinning I can't imagine this actually working. The latest SF I watched (mission to mars) had a wide rotating cillinder somewhere in the middle of a much longer cillinder which formed the main ship. Now imagine yourself moving from...

Considering artificial gravity can be created in a large enough tube orbiting an axis at a fast enough speed, consider the following: If a spaceship is in a fixed orbit around the earth, wouldn't it be bound to Earth's axis by its gravitational pull? And if so, since the Earth rotates at...

In lecture 5 of MIT's OCW 8.01 , Prof. Lewin says that when you're in in uniform circular motion, the perceived gravity is always in the opposite direction as the push or pull (so if you're holding onto the end of a rope that's being spun around horziontally, the rope is pulling on you and you...

Hi all. I posted a question here once before for a sci-fi writing project, and I'm back again to pick the brains of some people more left-brained than myself. Here's the scenario: Imagine you're in a spacecraft with a rotating centrifuge, to create artificial gravity for the astronauts...

Homework Statement Figure 5.18 shows a space station rotating about an axis. Because of the rotational motion, any object located at a point P on the interior surface of the station experiences a centripetal force directed toward the axis. The surface of the station provides this force by...

Homework Statement Spinning Space Ship One way to provide artificial gravity (i.e., a feeling of weight) on long space voyages is to separate a spacecraft into two parts at the ends of a long cable, and set them rotating around each other. A craft has been separated into two parts with a...

I wrote a brief technical paper on the research and concepts for creating artificial gravity in space using centrifuges for my Mechanical Engineering class. I would just like to share it with the Physics world...

When an object is present in a rotating satellite it is pressed towards the rim of satellite.What in the world makes it press?

I was recently reading about artificial gravity and generating it in space, especially by centripetal force using Stanford Tori and Bernal sphere (only Wikipedia and these to articles, but if anyone has any more resources, I would be glad to read them, I couldn't find anything else in my...

This is a spoiler for all Artificial gravity space crafts. If somebody thinks that he can do whatever he can on earth, on the Space Craft, then here is bad news: No football, no soccer, no cricket, no birds can exist on the craft without confusion. :confused: Here is why: A projectile...

reading about circular motion has become very confusing for me thanks to the "centrifugal force". I have tried reading a lot of concepts presented on the internet but they haven't cleared away my doubts. In a rotating wheel, If there is no outward force acting on an object why does it remain in...

A little puzzle that's been in my mind for a while and I figured I would ask, in case someone a little more knowledgeable could shed some light on it. Assuming one had a spaceship formed by two "hoops," one inside the other. If one of the hoops rotated at a velocity high enough to provide a...

What are some of the obstacles scientist face with the idea of creating artificial gravity for a space station?

im struggeling with the notion of experiencing angular momentum in a spinning space station. to me it would seem that you wouldn't "stick" to the wall/floor simply because it was spining. for example, if you were floating in a vaccume in the center center of a tube like structure and it it...

Gravity in space is best simulated by rotation. If I were inside a rotating cylinder facing the direction of rotation (i.e. a window at my feet would show objects coming into view from the top of the window) and jumped straight into the air, would I land ahead of where I started or behind where...

can someone explain to me how can it be proof that the spinning-room-artificial-gravity, actually works? i mean, that if you take a huge wheel-like room, and spin it in the right velocity, the people inside will experience something that feels like gravity. well, I've mange to understand...

Homework Statement To create artificial gravity, the space station shown in the drawing is rotating at a rate of 1.10 rpm. The radii of the cylindrically shaped chambers have the ratio rA/rB = 3.85. Each chamber A simulates an acceleration due to gravity of 10.0 m/s2. (a) Find rA. (b)...
