Chapter 8 - Linear Momentum & Collisions | Learnify

Momentum is the language of interactions and collisions. This chapter shows how motion is governed when forces act for short times or systems interact internally. Chapter 8: Linear Momentum & Collisions builds a powerful conservation-law approach to mechanics. Instead of tracking forces at every instant, you’ll learn how momentum principles simplify complex interactions. In this video, you will clearly understand momentum and impulse, and how impulse represents the effect of force over time. The law of conservation of momentum is developed from physical reasoning and applied to a wide range of problems. You’ll study different types of collisions — elastic, inelastic, and perfectly inelastic — and learn how energy and momentum behave differently in each case. Explosion problems are explained using the same conservation principles, helping you see the unity behind seemingly different situations. The chapter also covers the concept of center of mass in one and two dimensions, showing how multi-particle systems can be analyzed as a single effective object under certain conditions. Finally, the video introduces rocket propulsion at an intuitive level, explaining how momentum conservation governs motion in space even without external forces. This lesson is ideal for high school and undergraduate students, engineering and medical aspirants, and anyone preparing for board exams, JEE, NEET, Olympiads, or university-level physics. A strong grasp of momentum makes rotational motion and advanced mechanics far easier. ⏱️ Use the timestamps in the description to jump directly to collisions, center of mass, or rocket propulsion for quick revision. 👉 Subscribe to the channel to strengthen your problem-solving toolkit in physics. 💬 Comment below: Which topic feels hardest — collisions or center of mass? #Physics #LinearMomentum #Impulse #ConservationOfMomentum #Collisions #ElasticCollision #InelasticCollision #PerfectlyInelastic #ExplosionProblems #CenterOfMass #RocketPropulsion #ClassicalMechanics #PhysicsFundamentals #JEEPhysics #NEETPhysics #BoardExams #UniversityPhysics
