Differentiate between balanced and unbalanced forces?

Question

Answer

When there is equal amount of force to on both sides then it is known as balanced force and when there is no equal amount of force then it is known as unbalanced force

Answer

# Balanced Force:

1) They don’t bring any change to the object.
2) They are equal in magnitude.
3) The result is always zero.
4) The object remains stationary.
5) They do not need any external force to balance, because it is already balanced.
6) Example: book kept on a table

# Unbalanced Force:

1) They change the position of the object.
2) They are not equal in magnitude.
3) The result is always greater than zero.
4) The object doesn’t remain stationary.
5) They need an external force to balance.
6) Example: book pushed from the table

Answer

**Differentiating Between Balanced and Unbalanced Forces**

**Introduction:**
In the field of physics, forces are central to the study of motion and how objects interact with each other. Forces can be categorized as either balanced or unbalanced. Understanding the difference between these two types of forces is crucial in comprehending the behavior and movement of objects.

**Balanced Forces:**
Balanced forces refer to a situation where the net force acting on an object is equal to zero. In other words, the forces are in equilibrium, resulting in a state of rest or constant velocity.

**Characteristics of Balanced Forces:**
1. **Equal Magnitude:** Balanced forces exerted on an object have the same magnitude. This implies that the forces are pulling or pushing with equal strength in opposite directions.
2. **Opposite Directions:** The forces act in opposite directions, cancelling each other out. This allows the object to remain in a state of balance without any acceleration.

**Examples of Balanced Forces:**
1. A book resting on a table: The downward force of gravity acting on the book is balanced by an equal and opposite force exerted by the table, resulting in a state of equilibrium.
2. A person standing on the ground: The force of gravity pulling the person downward is balanced by the normal force exerted by the ground, allowing the person to remain stationary.

**Unbalanced Forces:**
Unbalanced forces occur when the net force acting on an object is not equal to zero. In such cases, the object experiences acceleration or a change in velocity.

**Characteristics of Unbalanced Forces:**
1. **Unequal Magnitude:** Unbalanced forces have different magnitudes. The forces are not balanced, and one force is stronger than the other.
2. **Same Direction or Opposite Directions:** Unbalanced forces can act in the same direction, causing the object to accelerate in that direction. Alternatively, they can act in opposite directions, resulting in a change in velocity or rotational motion.

**Examples of Unbalanced Forces:**
1. A car accelerating forward: The force exerted by the car's engine is greater than the forces opposing motion, such as friction and air resistance. As a result, the car accelerates in the forward direction.
2. A person kicking a soccer ball: The force applied to the ball by the person's foot is greater than any opposing forces, causing the ball to accelerate and move in the direction of the kick.

In conclusion, balanced forces result in a state of equilibrium, where the net force is zero and there is no acceleration. On the other hand, unbalanced forces lead to acceleration or changes in velocity, as the net force is not equal to zero. Understanding the distinction between these two types of forces is essential in analyzing and predicting the motion and behavior of objects.
