Definition of Balanced and Unbalanced Forces
When two or more forces acting on a body are equal in magnitude and opposite in direction, the body is said to be under balanced forces. On the other hand, when two or more forces acting on a body are unequal in magnitude and/or not opposite in direction, the body is said to be under unbalanced forces.

Characteristics of Balanced and Unbalanced Forces
Balanced Forces:
- The net force acting on the body is zero.
- The body remains at rest or moves with a constant velocity.
- The acceleration of the body is zero.
- The forces acting on the body are equal and opposite.

Unbalanced Forces:
- The net force acting on the body is not zero.
- The body either accelerates or changes its direction of motion or both.
- The forces acting on the body are not equal and opposite.

Examples of Balanced and Unbalanced Forces
Balanced Forces:
- A book lying on a table.
- A car moving with a constant velocity on a straight road.
- A person standing still on the ground.

Unbalanced Forces:
- A ball thrown upwards into the air.
- A car accelerating from rest.
- A person pushing a heavy box.

Conclusion
In conclusion, the state of an object being under balanced or unbalanced forces depends on the net force acting on the body. If the net force is zero, the body is under balanced forces, and if it is not zero, the body is under unbalanced forces. Understanding balanced and unbalanced forces is essential in comprehending the motion of objects.

If two individual forces are of equal magnitude and opposite direction, then the forces are said to be balanced. An object is said to be acted upon by an unbalanced force only when there is an individual force that is not being balanced by a force of equal magnitude and in the opposite direction.
