What is force and explain balanced and unbalanced force?

Question

Answer

Force is a push or pull on an object that produces acceleration in the body on which it acts...
Balance force is the force in which object does not change its motion to and its net force is equal to zero is called balanced force........

Unbalance force is the force in which net force is not equal to zero and object change its motion.

Answer

Force is a push or pull which either changes or tries to change the state of rest or state of motion or direction of motion of an object.
Balanced force_ Pair of forces that are equal in magnitude but opposite in direction, their resultant force is zero
Unbalanced force_ Unequal forces acting on a given object, their resultant force is non-zero

Answer

Force:
Force is a physical quantity that can change the state of motion or shape of an object. It is a vector quantity, which means it has both magnitude and direction. Force is measured in newtons (N).

Balanced Force:
Balanced forces are two or more forces acting on an object that cancel each other out and do not cause any change in the object's motion. When the net force on an object is zero, the forces are said to be balanced.

Key Points about Balanced Force:
- Balanced forces do not cause any change in the object's motion.
- The object may be at rest or moving with a constant velocity.
- The forces acting in opposite directions on the object are equal in magnitude.
- The net force on the object is zero.

Unbalanced Force:
Unbalanced forces are two or more forces acting on an object that do not cancel each other out and cause a change in the object's motion. When the net force on an object is not zero, the forces are said to be unbalanced.

Key Points about Unbalanced Force:
- Unbalanced forces cause a change in the object's motion.
- The object may start moving, stop moving, or change its direction.
- The forces acting on the object are not equal in magnitude.
- The net force on the object is not zero.

Examples of Balanced and Unbalanced Forces:
- If you push a stationary box with a force of 10 N to the right, and your friend pushes it with a force of 10 N to the left, the box will remain at rest. The forces are balanced.
- If you push a stationary box with a force of 10 N to the right, and your friend pushes it with a force of 5 N to the right, the box will start moving to the right. The forces are unbalanced.
- If you kick a soccer ball with a force of 20 N to the right, and the goalkeeper applies a force of 20 N to the left, the ball will continue moving in its original direction. The forces are balanced.
- If you kick a soccer ball with a force of 20 N to the right, and there is no opposing force, the ball will continue moving to the right with an acceleration. The forces are unbalanced.

Conclusion:
In summary, forces can be balanced or unbalanced. Balanced forces do not cause any change in an object's motion, while unbalanced forces cause a change in an object's motion. Understanding the concept of balanced and unbalanced forces helps us analyze and explain the motion of objects in various scenarios.
