Artifical Gravity Final

Artificial gravity aims to replicate the effects of gravity in space through centrifugal force. One method is to rotate a large ring-shaped space station, which would create an outward force and "gravity" on the outer rim. However, building such a large structure is challenging. Another option is centrifuges aboard spacecraft, where spinning would create an inward force experienced as gravity towards the "floor." While this could address health issues in microgravity, simulated gravity wouldn't be identical to natural gravity on Earth due to coriolis effects.

Artificial gravity

Introduction
Science fiction has explored the idea of artificial gravity for a long time, and
numerous depictions of the concept have been explored in the works science fiction.
Essentially all sci-fi spaceships have some form of artificial gravity. For example In the
Star Trek u​ niverse, artificial gravity is achieved by the use of "gravity plating" embedded
in a starship's deck,​ but the technology behind this is never quite explained.

What is Artificial Gravity?


Artificial gravity is a collection of systems that replicate gravity, which is used to
make people in space feel more comfortable and to make working in space easier.
When artificial gravity is used, people experience conditions similar to those on the
surface of the Earth. The use of artificial gravity also reduces the problems associated
with prolonged periods of weightlessness, if you spend too long in Zero Gravity you
experience loss of muscle tone and can develop serious musculoskeletal problems.
Artificial gravity is essential for long-term flights, the need for artificial gravity is one of
the major barriers of space travel.
Research
When it comes to generating gravity the most efficient way, using current
technology, is to create a centrifuge. ​Centrifugal force (or "center-fleeing") is an outward
force apparent in a rotating reference frame, for example it might also be used to
describe why we tend to slide to the outer side of a car going around a curve. So
applying this method aboard a spaceship would produce a pulling sensation toward the
"floor" that would mimic the effects of gravity​, thus producing ​artificial gravity​. One of
the most straightforward ways to simulate gravity is to create a rotating a spaceship or
structure. Many space station concepts during the 20th century frequently used a
ring-shaped station, in which the outer rim continually spun to generate artificial gravity.
Astronauts would be able to enter the ring, and would feel the centrifugal force created
by its rotation, the movie ​Space Odyssey m ​ ade the concept popular. The problem with
this method is that this necessitates building a very large structure, and places
limitations on the design, which illustrates how challenging it is to create gravity which
will work effectively.

Conclusion
-Though simulating gravity is possible it wouldn't be exactly the same as it is on earth. A
large Coriolis force would be present, and things would fall in curves instead of straight
lines. In a spaceship designed to produce artificial gravity, the wall would become the
floor, and the floor would become the inner wall of the ship,​ so ​you'd walk around
perpendicular to the "wall" you were stuck to.
