Can people create an object having gravity?

All objects have gravity regardless of whether they are moving or not.

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.

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).

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.

looking at that equation you can see that speed and velocity and rotation does not matter.

therefore 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!

Celestial bodies rotate because of gravitational forces exerted on them, but the rotations have nothing to do with the strength of the gravity fields itself.

Gravity is the force which acts on the object with mass.

any object with mass has gravity, the force of gravity of a steel ball is very small.

All matter has gravity, regardless of whether it is moving or not. As velocity increases, so does mass and therefore gravity, but this is something different. Stationary objects have mass, and therefore gravity.
