Difference between balanced and unbalanced forces

The balanced force

implies the force that does not change the state of movement of the object. On the contrary, the unbalanced forces they are those that determine the change in the state of movement of the object.

Have you ever observed that every time you want to move an object, it is pushed or pulled? In physics, the movement exercised (push or pull) on the object is defined as force, which arises due to the interaction of the object with another. able to change the size of the object's speed, the direction of movement and even the shape and size of the object. Strength takes place in pairs; they can be balanced or unbalanced.

As we look around, there are many cases where we can find the occurrences of these two forces. This excerpt attempts to clarify the basic differences between balanced and unbalanced forces.

Comparative graph

Basis for comparison Balanced forces Unbalanced forces
Sense When the forces exerted on the object are of equal size but in the opposite direction, the forces are known as balanced forces. When the forces applied to the object are of unequal size, the forces are known as unbalanced forces.
Size equal Not the same
Direction In front of Equal or opposite
Stationery object Stays at rest It moves in the direction of greater strength.
Moving object Keep moving at the same speed. Change its speed and direction.
Net strength Zero Not null

Definition of balanced forces

Balanced forces, as the name suggests, are the forces that balance each other, when they act on an object, causing the object to maintain its balance and not accelerate. If the forces applied to the object are of equal amplitude but opposite in direction, the forces are said to be balanced.

When balanced forces are applied to a stationary object, it remains immobile, but when applied to a moving object, it continues to move with a constant speed and the same direction. The net force (ie the total or resulting force exerted on the object) will be zero because the forces act in the opposite direction, which cancels each other.

Definition of unbalanced forces

The force that is not counterbalanced by a force of equal width and diametrically opposite direction, which causes an imbalance of the object and eventually accelerates, known as unbalanced forces. The magnitude of the applied forces is not the same, just as the direction in which the force is applied can be the same or different.

In unbalanced forces, the net force will be different from zero and the object will move in the direction of the greater force. Therefore, it causes the acceleration of the object, that is, the stationary objects move, the moving objects accelerate, slow down, stop or change their direction of movement.

Key differences between balanced and unbalanced forces

The points presented below are substantial as regards the difference between balanced and unbalanced forces:

  1. When the individual forces applied to an object are of the same entity and in the opposite direction, the forces are known as balanced forces. On the other hand, when the forces acting on the object are of different sizes, then the forces are known as unbalanced forces.
  2. In balanced forces, the magnitude of the two forces equals, while, in the case of unbalanced forces, the magnitude of the two forces is not equal.
  3. In balanced forces, the two individual forces act in the opposite direction. Conversely, in unbalanced forces, the individual forces act in the same direction or in the opposite direction.
  4. Balanced forces cause a stationary object to remain at rest. In contrast, unbalanced forces move a stationary object in the direction of the greater force.
  5. If the object is moving and balanced forces are applied, the object will continue to move with the same speed. On the contrary, if unbalanced forces are exerted on a moving object, slow down, accelerate, stop, or its direction will be changed.
  6. If the forces exerted on the object are balanced, the net force will be zero, since the two individual forces cancel each other and will not determine the change in its state of rest / movement.
  7. Otherwise, if the force applied to an unbalanced object, the net force will be different from zero, which will result in the change of its state.

Conclusion

To sum up, we always need an unbalanced rather than balanced force, to change the size or direction of the object's movement, which will continue to exist until the force is applied to the object. Although when this force is removed, the object will remain in motion, with the speed acquired by it, until then.

If you want to determine, what balanced or unbalanced force, first of all you have to identify which forces work on the object and also in which direction. If the forces counterbalance each other, then the forces are balanced, but when they do not, then the case of unbalanced forces.
