L-2 How Forces Affect Motion | Ch-6 Class 9 Science | New NCERT 2026-27 | Exploration | Tarif Sir

Struggling to understand why a moving object eventually stops, or why pushing something heavy takes so much effort? In this lecture, Tarif Sir breaks down Friction and Newton's First Law of Motion with simple real-life examples, easy activities, and clear step-by-step explanations designed for Class 9 Science board exam preparation. What You'll Learn: What friction is and why it always opposes motion Why a moving bicycle eventually stops even without brakes How much force is needed to move a stationary object The four main forces acting on a box being pushed (applied, friction, gravitational, normal) What would happen if friction disappeared from the world Activity 6.1: Coin and rubber band experiment on wooden, laminated, and marble surfaces Activity 6.2: Measuring friction using a spring balance Meet a Scientist: Isaac Newton and the concept of inertia Newton's First Law of Motion with Examples 6.2 and 6.3 Position-time and velocity-time graphs for objects with zero net force Pause and Ponder solutions for Questions 3, 4, and 5 This lecture is designed for students preparing for CBSE, RBSE, MPBSE, HPBSE, and UBSE board exams, following the New NCERT Exploration curriculum for Class 9 Science. About the Teacher: Tarif Sir has been teaching Class 9 and Class 10 Science with a strong focus on building real conceptual clarity rather than encouraging rote memorization. His teaching style breaks down every topic into simple, relatable, everyday examples so that students dont just memorize definitions but genuinely understand the science behind them. This approach makes his lectures especially useful for students preparing for board exams, as it helps them tackle both direct and application-based questions with confidence.
