FAQs on Balanced and Unbalanced Forces Video Lecture - Crash Course: Class 9 (Hinglish)

1. What is the difference between balanced and unbalanced forces?
Ans. In simple terms, balanced forces are forces that cancel each other out, resulting in no change in an object's motion. Unbalanced forces, on the other hand, cause a change in an object's motion as they do not cancel each other out.
2. How can you determine if forces acting on an object are balanced or unbalanced?
Ans. To determine if forces acting on an object are balanced or unbalanced, you need to calculate the net force. If the net force is zero, the forces are balanced. If the net force is not zero, the forces are unbalanced.
3. Can an object have both balanced and unbalanced forces acting on it at the same time?
Ans. No, an object cannot have both balanced and unbalanced forces acting on it at the same time. It can either have balanced forces, resulting in no change in motion, or unbalanced forces, causing a change in motion.
4. How do balanced forces affect an object's motion?
Ans. Balanced forces do not cause any change in an object's motion. They keep the object at rest or maintain its constant velocity if it is already in motion.
5. What are some examples of balanced and unbalanced forces in everyday life?
Ans. An example of balanced forces is a book sitting on a table. An example of unbalanced forces is a car accelerating or decelerating.
