If the object is not moving, then the only thing you can be sure of is that
since it's not accelerating, all of the forces acting on it add up to zero.
Just the fact that it's not moving is not enough information to tell you that
there are no forces on it.
The total of all the forces acting on an object is called either the metabolism respiration enzymes or photosynthesis
Please redefine question. All objects have all forces acting on them to some degree or another, with strong and weak nuclear forces, gravitational, electromagnetic being the fundamental forces. Or do you mean something like uniform compression forces, say of a submersible underwater being "crushed from all sides".
Say you are moving an object against the carpet flooring, you are the force and you are causing the object to move as well as you are creating friction between the carpet and the object. The force would be called the netforce, which is all the forces that are acting on an object.
Two forces acting in the same direction cause the body to speed up (accelerate) if the forces are acting in opposite directions, subtract one from the other. The difference is the net force on the body and will be the direction in which it accelerates. Obviously, if they're the same size and opposite in direction, providing the body is rigid (it doesn't deform, in other words), the stat of motion of the body will stay the same (either at rest or moving at a steady speed in a straight line).
If the forces are balanced they will have no action or the object, if not they will accelerate the object in the resultant direction of the two forces..
The forces acting on a stationary object are balanced. If you were to add up all the forces (taking the directions into account, you would get a total of 0. There are always forces acting on a object, such as gravity, so you cannot say that there are no forces acting on it. You can say that the forces are balanced.
Not much, really. If the object's direction is changing, then the velocity changes, and there are forces acting on it. The only thing we can say is that the net force acting on the object is either zero, or it is perpendicular to the movement.If the VELOCITY doesn't change, then the net force (the sum of the forces) is zero.

If the net force on an object is zero, we can say that the forces are balanced, or that they are in equilibrium(which really means the same thing). There may be forces acting on the object, but there is an equal and opposite force pushing or pulling in the opposite direction, and all the forces balance out. Alternatively, there may be no forces acting on the object at all.
That's the definition of "net force", so you might say "always". This refers to forces acting on the same object. If there are time-varying forces, the answer might be never!

That's usually called the object's "weight". Like say if you're talking about the forces of gravity between you and the Earth, the force of gravity acting on you is your weight on the Earth, and the force of gravity acting on the Earth is the Earth's weight on you, and they're equal.

It means the same as the sum of all the forces acting on an object. Note that since forces are vectors, they have to be added as such. For example, an book resting on a table has gravity pulling it down; on the other hand, the table is pushing the book upwards (by Newton's Third Law; since the book pushes down on the table). Adding all the forces together, you get a zero force - which must be so, for the object to remain at rest.
If an object is in static equilibrium (or "stable"), there is no net force acting on the object.
Two forces acting in the same direction cause the body to speed up (accelerate) if the forces are acting in opposite directions, subtract one from the other. The difference is the net force on the body and will be the direction in which it accelerates.
