I'm assuming your question is in reference to Newton's laws of motion which are:
1) For every action a equal opposite action--1N=-1N.
2) Force equals mass times acceleration-- F=ma. Gravitational force dictates that any and all objects of mass (m) accelerate to earth at the same rate (a) which is 9.8 meters/second squared (F=m(9.8)^2).
3) An object in motion tends to stay in motion while an object at rest stays at rest.

NET force
accelerating force
The Net external forces is the result force of two objects acting upon it. So if like two forces act on a book. One force exerts downward on the book and the other force pushes the table back on the book with the same amount of push and pull. Since both forces are pushing on each other with the same amount of energy the resultant force or net external force will be in equilibrium or zero.
An unbalance force means that the total force acting on an object, also known as the net force, is not equal to zero.
The basic equation is: force equals mass times acceleration.
The result of the combined forces on an object is called the net force. This net force determines the object's acceleration according to Newton's second law of motion, F = ma, where F is the net force, m is the object's mass, and a is its acceleration.
The result of unbalanced forces is a net force that can accelerate a body.
NET force
When mass is constant, the net force acting on an object is directly proportional to its acceleration. This is described by Newton's Second Law of Motion, which states that the acceleration of an object is equal to the net force acting on it divided by its mass. A larger net force will result in a greater acceleration, while a smaller net force will result in a smaller acceleration.
The result of an unbalanced force is an acceleration. Newton's Second Law (as it is usually stated nowadays) gives the relationship; it states that: F = ma (net force = mass x acceleration)
When unbalanced forces act on an object, it will experience acceleration in the direction of the net force. This can result in the object moving in the direction of the greater force or changing its speed or direction. The magnitude of the acceleration is directly proportional to the net force applied to the object.
There's no such thing as "a net force". "Net" means what you have at the end when all is said and done, usually the result of adding up all the pieces. The 'net' force on an object is the combination of the strengths and directions of all of the separate individual forces acting on it.
Mass and Net force
in the same direction as the net force, directly proportional to it, and inversely proportional to the object's mass.
If you double the net force on an object, the acceleration of the object will also double. This is in accordance with Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it.
In neutrons, the net force is typically zero because they are electrically neutral particles. This means that the attractive nuclear force holding the neutrons together is balanced by the repulsive electromagnetic force between the neutrons. As a result, neutrons do not experience a net force in most situations.
The net force on the crate sliding at a constant speed is zero. This is because the applied force of 75 N is balanced by the frictional force opposing the motion. As a result, the crate does not accelerate, and the net force is zero.
