Free notes + solved JEE problems for this lesson: https://rankdeterminant.com/go/yt-phy... All lessons of this unit:    • JEE 2027 Physics | Unit 5 Rotational Motion   Rotational motion problems at JEE Advanced level, from Part C of the unit problem bank, taught like a live class: an impulse at one end of a free rod and why the far end moves backwards, a solid sphere rolling without slipping on a pulled plank, the rolling condition on a moving surface, and the topper's check of a hinge-force answer at special positions. Chapters 0:00 Introduction 0:32 Part C: two or three ideas in every problem 0:57 Idea 1: a free rod gets an impulse 2:03 Idea 2: rolling on a moving surface 2:47 Topper's trick: check at special positions 4:03 Example 1: impulse at one end of a free rod 5:41 Example 2: sphere rolling on a pulled plank 7:46 Quick revision: impulse, moving surface, special positions A free JEE paper every day and a full JEE Main mock every Sunday: https://rankdeterminant.com/go/yt-dai...
