why when u release things in the space(w/o gravity)they orbits round themselves?

Question

like a bolt

Answer 1

if the objects not close to any celestial body, it just 'floats'. like a bottle in the ocean.

Answer 2

in space, there are gravitational forces. cause the distance between an object and another object, say the sun or other obects with a lot of mass (and thus, non negligible) objects. with this, the object in space would seem weightless, but they actually have very very little force that is acting on them, but they are small, so the layman would think that it is stationary.

But when the object is infinitely far away from other objects, then it doesn't matter about the magnitude of the mass, but the object would not have any gravitational forces whatsoever. It will remain still.

In order for objects to orbit and move in a circular motion, it must have what is called a centrepetal force, a force that attracts the object to the centre of the orbit.

So without gravity (so says the question), assuming there are no other forces. An orbit can not be formed. Due to the lack of a centrepetal force.

Answer 3

everything in the universe that has mass has gravitational pull. So even while the earth roates around the sun, the earth is also pulling on the sun, our orbit is the happy medium between the two forces. That is why even though the moon rotates around the earth it is still large enough to have an effect on our tides. So even when it seems like something has been released in space all by itself there is actually something pulling on it.

Answer 4

All objects have a small amount of gravity, however on earth the gravity of the large mass of earth cancells out the gravity of other objects, in space the gravity of earth does not exist, making smaller objects revolve around larger ones.

Answer 5

Well, they don't orbit around themselves, they spin on one or more axes (multiple axis). The reason is that when they are released, they probably are not released with the same amount of pressure on all parts. The pressure that releases them is stronger on one part which causes the item to tumble and spin. Also, gravitational pulls from other object (stars, planets, moons, space stations etc) will pull on the object even if it is not spinning and cause it to spin.

Answer 6

I think that when things are elease into space, they orbit other boddies because of the gravity that the bigger object is exerting on the smaller one.

Answer 7

Because theres no gravity in space

Answer 8

if you throw something into space it wont orbit around it self but it would start travelling at the constant velocity in to the space for ever and ever.

Answer 9

the law of gravity states that there is no place in the universe that is free altogether from gravity

Answer 10

I say because all matter has it's own gravitational pull.

The larger the mass the stronger the pull.

not sure though.
