Описание: Welcome to Lecture 4 of Physics 9th Class - NBF | Chapter 4: Dynamics - II (FBISE New Book) on Concept & Exam!

Topics covered in this Lecture:
🔹 Lecture 4: Centripetal Force, Orbital Motion of Satellite & Types
• What is Centripetal Force
• Formula of Centripetal Force (Fc = mv²/r)
• Direction of Centripetal Force
• Circular Motion explanation
• Orbital Motion and Orbital Velocity
• Mathematical Proof of Orbital Motion of Satellite
• Derivation of Orbital Velocity Formula
• Planetary Model explanation
• Types of Satellites (Natural & Artificial)
• GPS Satellite example and its working principle
• Real-life applications of satellites
This topic is very important for board exams and also builds the foundation for higher classes and entry test preparation.
Understanding orbital motion helps students connect gravity, circular motion, and satellite technology in a practical way.

This playlist covers all key topics of Chapter 4 with clear explanations, important formulas, solved numericals, and step-by-step problem-solving techniques. Perfect for students of 9th Class (FBISE) preparing for Board Exams, Entry Tests, or O/A-Level equivalence.
