Forces act by means of exchange particles. There are four basic forces (which operate in numerous different ways) each having its own exchange particle. The force of gravity is conveyed by the graviton. The electromagnetic force is conveyed by the photon. The two nuclear forces are conveyed by mesons.
A particle that is exerting a force will emit an exchange particle, and a particle which is experiencing a force will absorb that exchange particle. That is essentially how it works, on a subatomic level. There are also mathematical equations which describe the forces, for example, the electromagnetic force is described by Coulomb's Law.
If the sum of all forces acting upon an object is not zero, then the object will accelerate. (Newton's first law)
Equilibrium
Objects move according to their net force, or the total amount of force acting on them. Balanced forces are just that, balanced. An object with balanced forces will not move because the opposing forces will cancel each other out. However, if there are unbalanced forces, the object will move in accordance with the force that is greater. When moving though, there is always friction. Whether you be underwater, on the ground, or in the air there is always friction on the Earth. (Besides vacuums, of course.) Force is equal to mass x acceleration. With that you can find the forces of the object if you know its mass and acceleration.
Two forces equal in size and opposite in direction are balanced, not unbalanced, because they cancel each other out. Any set of forces which has a resultant of zero is said to be balanced.
There is no such thing as "an unbalanced force". There are only forces. When two or more separate forces act on the same object, the GROUP of forces may be balanced or unbalanced. If the sizes and directions of all the individual forces add up to zero, then the GROUP of forces is balanced. If one of them changes or goes away, then the GROUP of forces is unbalanced.
Forces that cancel each other out are coplanar, all reside in the same plane.
The action and reaction forces are the forces that cancel each other. They do not change an object motion or cause the object to accelerate.
When forces cancel each other out and do not change an object's motion, it is in a state of equilibrium. This means that the net forces acting on the object are balanced, resulting in no acceleration or change in velocity.
When the forces on an object cancel each other out, the forces are said to be balanced. This means that there is no resultant force acting on the object, and as a result, the object will either remain stationary or continue to move at a constant velocity.
If the net force on an object is zero, the forces are said to be balanced. This means that the individual forces acting on the object cancel each other out, resulting in no overall change in the object's motion.
Forces that don't cancel each other out are called unbalanced forces. When two or more forces act in opposite directions and do not cancel each other completely, they create a net force that results in an acceleration of the object.
When forces cancel each other out and do not cause changes in motion, it is known as a state of equilibrium. This means the net force on an object is zero, resulting in no acceleration.
When all the forces on an object cancel each other out, the object is said to be in a state of equilibrium. This means that the object will either remain stationary or continue moving at a constant velocity.

Forces that cancel each other out are called balanced forces.
The forces are said to be in equilibrium in that case.
The force's don't cancel out each other, they act on different objects. Forces can cancel only if they act on the same object.
