only the mass will change, the mass is the force applied by an object.
gravity :)
An orbit. In fact, orbits are not usually exactly circular. They are "elliptical".
No. The mass of any object is considered to be an intrinsic constant property, i.e. it's a characteristic of the object and it doesn't change, no matter where the object goes or what happens to it. The weight of the object may change, because that's just the force of gravity caused by whatever large body the object happens to be near, like the earth or moon.
it is lighter or heavier
If the object is gravitationally bound to the sun, it is part of the solar system. If not, not.

Depends on the charge (and conductivity) of the "other" object.

Speed describes the distance traveled by an object divided by the time in which the distance was traveled, if the direction is not specified.
No. Mass is an intrinsic property of an object and doesn't change, regardless of the environment into which the object is placed. The weight of an object, however will change depending on the gravity acting upon it.
NO
No, you cannot.
physical change, because you are changing the physical property of the object. you are causing the change by hammering it. If you were to put some kind of chemical on it and it changed the physical property of the object that would be a chemical change.
distance
Size independent property is physical properties that do not change when an object changes. Size dependent is physical properties that change when the size of an object changes.
An object's size is a physical property of the object.
