is there any g-force in space?

Question

say for example i was in a space ship doing about mach five and i wished to accelerate to mach 6 would there be any g-force? (hypothetically speaking)

Answer 1

What do you mean by g-force?

Do you mean a gravitational force? The answer is yes, there are gravitational forces in space.

Do you mean the centripetal force you feel in a tight curve, like on a roller coaster? The answer here is yes as well. Any time you move in a circle or arc you must accelerate. This acceleration is accomplished by centripetal force. The "g-force" you feel is nothing more than your body being accelerated toward the center of your arc or circle. You can most definitely travel in a circular path in space.

Answer 2

G Force In Space

Answer 3

If you are in a rocket and are accelerating then, yes, there is g force. If you are at the same altitude that the satellites orbit at then there still is a g force there as well--although a bit less compared to the surface. If you are really deep in space, far away from any other massive objects, the the only g force you would experience would be of a non gravitational origin.

Answer 4

There is gravity everywhere in space but it decreases by the inverse square law the further you get from the source (the sun, the planet, the galaxy). Far from bodies you have very little gravity and are practically weightless.

I believe you are asking if you would feel the "Gs" if you accelerated in space. Probably not, you feel those forces because you are in Earth's gravitational feild, this is why when free falling you feel negative, or zero "Gs"- you feel weightless.

Answer 6

Newton's first law of motion:
"Objects in motion tend to stay in motion, and objects at rest tend to stay at rest unless an outside force acts upon them."

This is where the concept of inertia originated.

Basically, if you have a change in speed (an acceleration) you are going to experience g-forces. (G-forces are simply the relation of your acceleration to the acceleration of gravity on Earth. So if you go from 0 meters per second to 100 m/s in 2 seconds, you will have accelerated at a rate of 50 meters per second squared, which is 5 times the acceleration of Earth's gravity, so you would have experienced 5g's.)

Answer 7

Of course! Gravitanoal force is everywhere in Space. Thats why the Earth orbits the Sun. Gravity causes two objects with large masses to attract. Thats why Satelitles orbit the earth, because their masses are attracted.

It is the force of gravity that holds our moon in orbit around the Earthy, our planet Earth in orbit around the sun - a star - and holds our sun in orbit around the center of the Milky Way galaxy. It is what spacecraft must overcome to go into orbit, to leave the Earth to go to the moon, and to leave our solar system to travel into outer space. The forces felt when a manned spacecraft accelerates, decelerates, or changes direction are not examples of gravity, but of inertia. They are called "G-forces" because they increase or decrease a person's apparent weight. If a person is in an orbiting spacecraft, such as the Space Shuttle (after it reaches orbit) or International Space Station (which is in a fixed orbit around the Earth), the force of gravity pulling him/her - and the spacecraft itself - toward the Earth is exactly equaled by the opposite force of inertia caused by the constant direction change of the spacecraft in its circular path. He/she will feel "weightless" because of this balance. If a person is in a spacecraft which is "coasting" unpowered toward the Moon or Mars, he/she will feel a slight pull of gravity from Earth, but this pull will decrease as the spacecraft moves farther away from Earth. When the spacecraft crosses the "boundary" where the pull of gravity of Earth is matched by the pull of gravity of the destination (the Moon or Mars), weightlessness will occur.

Answer 9

The only way to completely rid oneself of gravitational forces would be leaving the universe, a topic which I will leave to the theoretical physicists and science fiction writers. The gravitational force exerted between two objects is described by the equation

F=(GMm)/(r^2)

where:
"F" is the gravitational force
"G" is the gravitational constant, 6.67x10^-11
"M" and "m" are the masses of the objects
"r" is the distance between them

The weightlessness of objects in orbit is due to the fact that they are effectively in constant freefall around the object they are orbiting–Earth, in most cases. According to the weak equivalence principle, this freefall is indistinguishable from weightlessness.

Answer 10

all changes in speed create a g-force to the human body... even in space
