Balanced Force

One might hear the term Balanced and Unbalanced Forces a lot while dealing with physics. Have you ever wondered what these forces are? To understand Balanced and Unbalanced forces, we need to first understand what Force is. Force can be defined as the pull or push applied on an object. We apply force, or force is applied to us in almost every aspect of our daily life. It is the driving factor in almost every phenomenon in the universe. From the gravitational pull of the sun, which binds the solar system together to the lifting up of a pencil by a child, everything is an example of force.

Force can be of two types:

  • Balanced force
  • Unbalanced force

According to Newton’s First Law,

A body at rest or in motion will continue to remain in the unchanged position unless an external force is applied to it.

Given this context, let us look into what each of these forces means.

What is a Balanced Force?

A force where two forces of equal size, act on a body, in opposing directions is known as a Balanced Force. In Balanced Force, a body continues to be in its position i.e. it may be continuously moving with the same speed and in the same direction or it may be still in its position.

What are the examples of Balanced Force?

Suppose you are pushing a wall and as expected, the wall does not move and neither do you. It means that you and the wall are exerting a balanced force on each other.

Balanced Force
An illustration of a man pushing against the wall. Here, the forces at play balance each other as a result of which the wall doesn’t move.

Let us look at the following illustration for better understanding.

Balanced Force
A game of tug of war with equally matched opponents is an example of balanced force

The image displayed above is a game of tug-of-war between two equally matched teams. Neither of the teams is able to pull the opposing team towards itself. This is an example of two balanced forces.

What is an Unbalanced Force?

A force where two forces acting in opposing directions on a body, are not equal in magnitude and in size, is known as an unbalanced force. In an unbalanced force, a body changes its position i.e. we can observe a moving object changing its direction, either increasing the speed or decreasing the speed and a body at rest starts to move and vice versa.

What are the examples of Unbalanced Force?

Practically anything that moves is a result of the exertion of unbalanced forces on it. If you kick a football and it moves from one place to another, it means that unbalanced forces are acting upon it.

Unbalanced Force
Ball moves from one place to another after kicking it. This is an example of unbalanced force.

Let us look at the following illustration for better understanding.

Unbalanced Force
One person significantly heavier than the other creates a condition of unbalanced force in a seesaw

The above image shows two people on a seesaw. The person on the right is significantly heavier than the person on the left and the seesaw is effectively tilted towards him. This is an example of two unbalanced force.

Now that we know what each of these forces are, let us look at their differences.

The difference between balanced and unbalanced force

Balanced forces
Unbalanced forces
Equal in magnitude. Unequal in magnitude.
Opposite in direction. Can be in any direction but opposite.
Does not cause any change in the state of motion of the object. Causes change in the state of motion of the object.
