8. Pulley Block Problems in Rotational Motion 💀 | JEE Main & Advanced | NEET | Class 11 Physics

In Rotational Motion Lecture 08, we cover two highly important problem-solving topics. First, we briefly discuss the Work-Energy Theorem in Rotational Motion and understand how the work done by torque is connected with rotational kinetic energy. The major part of this lecture focuses on Pulley-Block Problems in Rotational Motion, where we solve some of the most important JEE Advanced PYQs and challenging problems involving rotating pulleys, blocks, tension, angular acceleration and energy. 📚 Topics Covered: 🔹 Work-Energy Theorem in Rotational Motion Work done by torque Rotational kinetic energy Application of the Work-Energy Theorem Important conceptual problems 🔹 Pulley-Block Problems in Rotational Motion 🔥 Blocks connected through a rotating pulley Tension on both sides of the pulley Translational + rotational motion together Angular acceleration of the pulley Acceleration of connected blocks Energy conservation in pulley systems Tough and important JEE Advanced problems Selected JEE PYQs 🎯 This lecture is especially useful for students who want to master mixed translational and rotational dynamics and learn how to approach difficult pulley problems systematically. ━━━━━━━━━━━━━━━━━━━━━━━ 🎯 This Lecture is Extremely Important for: • JEE Advanced 🔥 • JEE Main • NEET • Class 11 & 12 Physics • Competitive Exams • JEE Advanced PYQ Practice 👨‍🏫 About the Teacher: Dheeraj Sir (IIT Delhi) • IIT Delhi Physics Mentor • Simplest Explanation Style • Advanced Concepts Made Easy • JEE Main & Advanced | NEET Physics 🔔 Don't Forget To: 👍 Like the Video 💬 Comment Your Doubts 📤 Share with Friends 🔔 Subscribe for High Quality Physics Content ━━━━━━━━━━━━━━━━━━━━━━━ #rotationalmotion #rigidbodydynamics #rotationaldynamics #PulleyProblems #PulleyBlockProblems #workenergytheorem #jeeadvanced #JEEAdvancedPYQs #jeephysics #jeemains #neetphysics #physics #iitjee #jeepreparation #RotationalMotionJEE #angularacceleration #torque #momentofinertia #energyconservation #physicsproblemsolving #jeepyqs #dheerajsir #DheerajSirPhysics #DheerajSirIITD #iitdelhi A uniform disc of radius R is spinned to the angular velocity w and then carefully placed on a horizontal surface. How long will the disc be rotating on the surface if the friction coeffiecient is equal to k? The pressure exerted by the disc on the surface can be regarded as uniform.
