Summary of moments class 9 ch 9?
Its a story about a man lushkoff who made his choice to be a beggar after being sent away from Russian choir where he used to sang due to his drunkeness. One day he meet a man Sergei, and explain how he was thrown out of school, where he thought. But Sergei noticed him who before met him on a street and said that he was a student expelled from school. But then he explain that he was saying lie he was not a student nor he was a beggar who feeled shame to beg. Then Sergei gave him work of chopping wood but he accepted but not willing to do work then Olga, Sergei cook gave him way but he received half of a rouble. Then Sergei sent he to gave a letter to an advocate, where he found work that pays thirty five rouble per month. After two years he met Sergei and explained him how Olga did work of chopping for him nothing done by Lushkoff and helped him a lot.

Summary of Moments Class 9 Chapter 9
Introduction:
The chapter "Moments" is a part of the NCERT Class 9 Physics syllabus. This chapter primarily focuses on the concept of moments, which is an essential topic in physics and engineering. Moments help us understand the turning effect of forces and their application in various real-life situations.
Key Concepts:
1. Moment of a Force: The moment of a force about a point is the measure of its ability to rotate an object about that point. It depends on the magnitude of the force, the perpendicular distance from the point to the line of action of the force, and the direction of the force.
2. Calculating Moments: The moment of a force can be calculated by multiplying the magnitude of the force by the perpendicular distance from the point to the line of action of the force. The unit of moment is Newton-meter (Nm).
3. Clockwise and Anti-clockwise Moments: If the rotation caused by a force is in the clockwise direction, it is considered a negative moment, and if it is in the anti-clockwise direction, it is considered a positive moment.
4. Conditions for Equilibrium: An object is in equilibrium when the sum of clockwise moments is equal to the sum of anti-clockwise moments. This condition allows us to solve problems related to the equilibrium of objects and the forces acting on them.
5. Practical Applications: Moments find applications in various real-life scenarios such as door hinges, seesaws, balance scales, and levers. Understanding moments helps engineers design and analyze structures and determine the stability of objects.
Key Formulas:
1. Moment of a force (M) = Force (F) × Perpendicular distance (d)
2. Clockwise moments = Sum of negative moments
3. Anti-clockwise moments = Sum of positive moments
4. Sum of clockwise moments = Sum of anti-clockwise moments (for equilibrium)
Conclusion:
The chapter "Moments" provides a detailed understanding of the concept of moments and their applications. By studying this chapter, students can develop problem-solving skills and gain practical knowledge about the turning effect of forces. This knowledge is not only essential for understanding physics but also has significant applications in engineering and everyday life.
