Gravity is the force that keeps things from flying off into space.
Friction is a force that opposes the motion of any object moving on it.
A energy/power that pulls a special type of metal together and and also push anothr type away...?
Only if the object is homogeneous, i.e. the mass is uniformly distributed. If the object is lumpy, or has thick spots and thin spots, then the center of gravity isn't related to the geometric shape. Consider a see-saw with a light kid on one end and a heavy kid on the other end. The geometric center is the mid-point of the board, but the center of gravity is closer to the heavy kid.
Physical state means solid, liquid, or gas. A gas is something like air. A liquid is something like water that you can pour. A solid is something like the floor or your chair.
