When two opposite forces of different magnitudes pull the wooden block, the block begins to move in the direction of the greater force. These forces are unbalanced forces.

Balanced forces are forces that are equal in magnitude and opposite in direction, acting on an object such that they do not change the state of rest or motion of the object.
If equal forces are applied by pulling both strings X and Y simultaneously, the block will not move. These forces are balanced forces.
When a force is applied by pulling string X, the wooden block begins to move to the right.
The common actions that illustrate the application of force to bring objects into motion are pushing, hitting, and pulling.
No, a force cannot be seen, tasted, or felt directly. However, we can always see or feel the effects of a force.
We typically describe the effort needed to change an object’s state of motion by saying that we must push, hit, or pull the object.
Some effort is required to put a stationary object into motion or to stop a moving object, which we ordinarily experience as a muscular effort.
Such observations suggested that rest is the natural state of an object because the ball would come to a stop after a short distance, implying that objects naturally tend to be at rest unless acted upon by a force.
Galileo Galilei and Isaac Newton developed a new approach to understanding motion that differed from the earlier belief that rest is the natural state of an object.
