Class 11 Physics | Equilibrium & Moment of Inertia | Unit V Part 2 | Lecture 11

An object can be perfectly still and still be about to move. This lecture covers the two conditions for equilibrium, then moment of inertia — rotation's version of mass. In this video: • Translational and rotational equilibrium — two ways to fail • The principle of moments, and how a see-saw balances • Moment of inertia: why shape matters as much as mass • Radius of gyration • The parallel axis and perpendicular axis theorems • Standard results for rings, discs, rods and spheres 📚 Physics (CBSE / NCERT) Unit V — System of Particles and Rotational Motion Chapter 6: System of Particles and Rotational Motion Part 2 Lecture 11 of the series Part of the complete Class 11 Physics series by ClassScribe — units and measurements, kinematics, laws of motion, work-energy-power, rotational motion, gravitation and more, with clear derivations and solved examples. 🚀 Study Smarter with ClassScribe 📝 AI mock tests (Boards, JEE, NEET & more) — https://www.classscribe.in/mocktest 📄 Previous-year questions, solved — https://www.classscribe.in/pyq ❓ Exam-style practice questions — https://www.classscribe.in/questions 🏠 Turn your own notes into quizzes & summaries — https://www.classscribe.in 🔔 Subscribe and follow this playlist for the complete Class 11 Physics course. #class11physics #ncert #physics #cbse #class11 #physicscourse #ClassScribe
