Centripetal Force and Acceleration- Unit 4 Rotational and Circular Motion- Class 11 #TP11 37

Class 11 Physics | Chapter 4: Rotational & Circular Motion | Centripetal Force & Centripetal Acceleration Lecture In this video, Sir Muhammad Talha clearly explains the concept and derivation of Centripetal Force and Centripetal Acceleration for Class 11 Physics (Unit 4: Rotational and Circular Motion) strictly adhering to the BIEK Karachi / Sindh Board curriculum. Topics covered include real-life examples of circular motion, definition and concept of Centripetal Force, Centripetal Acceleration due to change in direction of velocity, and step-by-step geometric proof/derivation using similar triangles for both linear (a_c = v²/r) and angular (a_c = rω²) terms. 📌 Useful Resources & Detailed Notes: https://talhaphysicsacademy.blogspot.... ⏱️ Timestamps: 00:00 - Real-Life Examples & Introduction to Circular Motion 01:11 - What is Centripetal Force?
