L-5 How Forces Affect Motion | Ch-6 Class 9 Science | New NCERT 2026-27 | Exploration | Tarif Sir

Newton's Third Law comes alive in this lecture through rocket launches, gun recoil, and everyday examples of action and reaction. Tarif Sir wraps up the core concepts of Chapter 6 with the balloon-rocket activity, the Chandrayaan-3 soft landing, force between the Earth and a falling fruit, and a full walkthrough of Examples 6.7 and 6.8. This is Lecture 5 of the New NCERT Exploration series on Chapter 6, How Force Affects the Motion. What You'll Learn: Newton's Third Law through Activity 6.7: the balloon rocket demonstration How rockets launch and achieve soft landings using action-reaction pairs (Chandrayaan-3 Vikram Lander example) Why Newton's Third Law applies to both contact and non-contact forces (magnets, static charges) Why the fruit falls toward the Earth but the Earth does not visibly move toward the fruit Pause and Ponder Q9: why a firefighter struggles to hold a hose pipe Pause and Ponder Q10: changing a spacecraft's velocity with no gravity acting on it Example 6.8: calculating the acceleration of a bullet and a recoiling gun Force acting on a system of objects: internal versus external forces Boards Covered: CBSE, RBSE, MPBSE, HPBSE, UBSE About the Teacher: Tarif Sir has built a teaching style around conceptual clarity rather than rote memorization, breaking down Physics ideas using everyday objects, simple demonstrations, and real-world examples so that Class 9 and Class 10 Science students genuinely understand the "why" behind each concept, not just the formula. His lectures are structured to align closely with the board exam syllabus, ensuring students preparing for CBSE, RBSE, MPBSE, HPBSE, and UBSE board exams are fully covered without needing to look elsewhere. The engaging, conversational delivery keeps students following along step by step, making even tricky topics like Newton's Laws of Motion approachable and exam-ready.
