9th physics new book 2025 | Chapter 3 Dynamics I first half chapter cover #physics #punjabboard2025

This is the new book of class 9 physics published by PCTB or Punjab curriculum and textbook board Lahore for all Punjab boards. In this lecture of Chapter no 3 DYNAMICS Physics Class 9. We will cover the topic kinematics 3.1 Concept of Force types of forces contact forces (friction, drag, thrust, normal force, air resistance, tension force, elastic force) non-contact forces (gravitational force, electrostatic force, magnetic force, strong and weak nuclear forces) 3.2 Fundamental forces Gravitational force electromagnetic force weak nuclear force strong nuclear force unification of weak nuclear and electromagnetic force 3.3 forces in a free body diagram 3.4 newton's laws of motion newton first law of motion Inertia Newton's second law of motion Effect of force on velocity Newton's third law of motion Forces acts in pairs 3.5 Limitations of Newton's Law of Motion Mini Exercise Mass and Weight Gravitational field 3.6 MASS and WEIGHT and Topic: 3.7 Mechanical and electronic balances. After studying this lecture, student will be able to: Understand the following terms: Mass weight electronic balance how to measure mass how to measure weight mechanical balance force meter digital force meter physical balance #class9 #9th #physics #mass #weight #balance #ustadshani #education #newbook #2025 mass and weight class 9th new book 9th class physics || new book 2025 || chapter 3 dynamics topic 3.6 mass and weight mechanical and electronic balances class 9th Dynamics, Contact & Non contact Forces Physics class 9 In Urdu 👍 Ch 3 ❤️ N.B.F 👌 New Edition 2025 My video is about introduction to Dynamics 1, what is force, what is contact force, what is non contact force and their application to our daily life. in this video I will give you the lecture about all these forces and make your concept clear about all these forces at home. after watching this video you will be able to understand physics and will make your all concepts clear and this video is very informative regarding students of general knowledge. keep watching my videos. Thanks.
