Can people create an object having gravity?

All objects have gravity regardless of whether they are moving or not.\n\n  Moving and object faster has no effect on the strength of its gravitational field. You must be thinking along the lines of magnetism or something.\n\n  Gravity depends only on the mass of an object. a piece of paper sitting on a desk has a gravity field. But becuz the paper's mass is soo small, its gravity field is too weak to be noticed (even by a nearby ant).\n\n   To calculate the strength of an objects gravity field the equation is (M1*M2)/(d^(2))  where M1 = the mass of the object ur finding the gravity stregth for, M2= the mass of any reference object you are using to determine the relative strentgh and d^(2) is the distance between the 2 ojects squared.\n\nlooking at that equation you can see that speed and velocity and rotation does not matter.\n\ntherefore any object a person creates will have gravity, just not gravity thats as strong as a planet's. to do that you would have to make an object as massive as a planet!\n\nCelestial bodies rotate because of gravitational forces exerted on them, but the rotations have nothing to do with the strength of the gravity fields itself.

If you were able to create a device that created a strong enough gravity field to suck in light, it would have the power to suck you in as well.\n\nSo, THEORETICALLY, it could be possible to construct such a device, but turning it on would be fatal.

Gravity is created by objects. "Down" is towards the center of the earth, where gravity is strongest. All planets, stars, asteroids, etc. have gravity.

There is one, that if you were to do it and found a way to publish the results, a lot of common people would be very interested.  It is the formation and collapse of a gravitational field.\n\nWere you to go to http://timebones.blogspot.com   and then to the November Archive, toward the bottom of that month you shall find "How to Form and Collapse a Gravitational Field".  What I have suggested has been done by myself, but I have never found anyone interested in the results.

Yes, anything with mass generates gravity.  Gravity will only effect things which have mass, so the fact that you are stuck down means you have mass, and thus gravity.

gravity and air resistance.

We know of no science that would permit Star Trek like gravity, which appears to be some kind of machine that can be turned off and on to make gravity. But I suppose some new discovery could make it possible. We just can't count on that.

NO!  If there was NO gravity then you wouldn't be able to do anything.  Everyone's hair would be all over the place.  Sports would be over forever.  Sex would be next to impossible.  This is just stupid.  \nBy the way, it's breathe (not breath).\n\nRev. Jank

It's possible to float something on an air current.  Of course you'll need a fairly strong current to float a physical body.  Then many who study metaphysics learn how to suspend physical objects in an energy field.  I've seen this done with examples like a tissue suspending between the hands or a pencil or similar objects.  I have not seen a person suspended yet but have spoken to a few people who claim to be able to levitate.  Who knows.  I'll keep an open mind and hope to actually observe something of that nature one day soon.

You could make a model of the solar system.  Use different sized Styrofoam balls for the planets.

The gravitational force holds it into a spherical shape.

No, because you might have other forces acting on the object such as magnetic force and gravity.

Yes, it could be done, but you would need a very large field. Even so, scientists have allready created super electromagnets to levitate stuff.

Mass interacting with gravity

We did something like this in my physics lab with an Atwood machine.  It was a pully with weights hanging from it.  I can't exactly remember how it worked, but maybe this will inspire you.  We also did something with an air track and these two masses colliding and we'd see which one would go in which diretcion.  You need a nearly frictionless surface, like an air hockey table or ice slab.

gravity and inertia\n\nread more below. It is really fascinating.

No. As a simple example, imagine a snake curled into a perfect circle. Its center of gravity is in the center of the cirlcle the snake forms, which is within the empty hole in the middle.\n\nCenter of gravity is the average location of an object's weight.
