Any kind of pull or push is a force. In order to illustrate a force, one must be familiar with two things. One must be familiar with the direction of the force and the size of the force. The forces, which are equivalent in size but in opposite direction are known as the balanced forces.
The balanced forces do not result in a change in motion. When the balanced forces function on an object at rest, the object will not move. The forces, which results in a change in the motion of an object are known as the unbalanced forces. The unbalanced forces are not opposite and equal.
