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).
You can either (1) measure what force is required to balance the other two forces, or (2) measure the object's acceleration.
You add them together, then from that you can say that this is the total force acting upon the object.
Two forces acting in the same direction add together. If those two forces are acting on an object, the object will accelerate faster than if there was only one force acting on the object.
The two forces are gravity and normal force.
If there is acceleration, there must be an unbalanced force. That is, the vector sum of all the forces acting on the object is not zero. It may be a single force, or several forces that don't add up to zero.
An object at rest, or an object with a constant velocity are the two possible states of an object with zero net force. An object with zero acceleration has zero net force. There many be several forces acting on the object, such as the force of gravity and the normal force of the ground. Even though an object sitting on the ground has two forces acting on it (gravity, and the normal force) the object does not accelerate because these forces are equal and opposite. An object with zero net force has all forces acting on it equally balanced and cancelling out
Air pressure.

Net force is a combination of all the foces acting on an object.If two forces are acting in the same direction you add the forces to calculate the net force
If there are two or more unequal forces acting on an object then the object will be acting on the 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.

You find the vector sum of all the forces. That is the resultant, or net, force.
Tension forces are two forces acting on one object, moving in opposite directions (away from one another) to stretch the object. Compression forces are two forces acting on one object, moving in opposite directions (towards one another) to compress or deform the object.
Then the object will not accelerate (if it is stationary, then it will remain stationary, if it is already moving it will continue to move at the same velocity until a force begins to act on it).
