Balanced Force - Definition, Examples, Characteristics, FAQs

Balanced and unbalanced forces are both fundamental concepts that hold the key to all movements or stillness of objects. Balanced forces are equal forces that apply simultaneously and oppositely on the object, maintaining a rest or consistent movement. Unbalanced forces change the object's motion, meaning either direction, acceleration or deceleration. Understanding these different forces enables an understanding of everyday motion dynamics.

What is Force?

Force is defined as a push or pull that modifies the rest or normal movement of an object or changes its direction or shape. This results in the object accelerating or increasing its overall pressure. The force unit is known as the Newton. A force metre can be used to measure its strength. N represents the unit of force. The force changes the condition of the object's momentum. Therefore force acts upon each object anytime an interaction between two objects occurs.

Two kinds of force can be:

1. Balanced force

2. Unbalanced force

What are Balanced Force and Unbalanced Force?

In physics, you could hear the words balanced and unbalanced forces a lot. Did you ever ask what these forces are? We first need to grasp what strength is to understand balanced and unbalanced forces. The pull or push on an item may be defined by force. In virtually every element of our daily existence, we utilise strength or power. In practically every phenomenon in the cosmos, it is the driving component. Everything is evidence of strength, from the gravitational pull of the sun, which connects the solar system to a child's elevation of a pencil.

Balanced Force Definition

If two forces on the body are equal, but opposed, then the forces are called balanced forces. If the force is balanced, a stationary body is motionless and the moving object moves at the same pace and in the same direction.

Balanced forces are those two forces that are equally large and act in the opposite direction on an object. Whenever an object is equilibrated, the object will remain steady or continue to move at the same speed and is called a balanced force in the same direction.

Balanced Force Formula

Assume that two forces acting on an object in opposition to one another have magnitudes $F_1$ and $F_2$. The net force applied on the item is thus zero because balanced force is defined as such.

Balance force $=F_1-F_2=0$
Consider a book on a table that has a mass of and a weight of mg, wherein g is the acceleration caused by gravity. According to Newton's law of motion , the table will generate an opposing force, called the normal force $F_N$. The two forces will balance each other out. The item won't move since the force's line of action and its action are parallel.

Therefore, the equation of balance force is
balanced force $=F_N-m g$

Balanced Forces Examples

A tug-of-war game with teams matched on both sides is an example of balanced strength. The team does not shift as the same force is exerted from each side.

In the book, the strength of gravity and the usual strength of the table, two vertical forces act. The gravity force is balanced with the natural strength of the table. The strength of gravity is not matched by the upwards force of the table when the table is removed and, consequently, the book is accelerated down.

Characteristics of Balanced Force

1. The condition of rest or movement of an item does not change with balanced forces.

2. Balanced forces do not permit a moving item to shift direction or speed.

3. The net forces acting are zero with balanced forces.

Unbalanced Forces

Unbalanced forces refer to forces that result in a net force acting on an object, causing a change in its state of motion. When unbalanced forces act on an object, they cause the object to accelerate, decelerate, or change direction.

Unbalanced Forces Examples

Some common examples include:
Rowing a Boat: When rowing a boat, the oars exert a force on the water that propels the boat forward. This force is greater than any opposing forces, like water resistance, leading to the boat's acceleration.
Bouncing a Basketball: Bouncing a basketball on the ground involves applying a force greater than the force of gravity pulling it down. This unbalanced force causes the ball to bounce back up.
Sliding on Ice: If you slide an object on ice, a small push can set it in motion due to the minimal friction. The applied force is greater than the tiny amount of friction, leading to the object's movement.

Difference between Balanced and Unbalanced Force

Let's look at the difference between balanced and unbalanced forces.

Similarities between Balanced and Unbalanced Forces

Balanced and unbalanced forces both involve the interaction of forces on an object, affecting its motion. However, they differ in their outcomes. Balanced forces result in no net motion, as equal forces cancel each other out. Unbalanced forces lead to a change in motion, accelerating or decelerating the object. Both concepts stem from Newton's laws of motion and highlight the dynamic interplay between forces and an object's behaviour.
