00:00 Setup and introduction
02:52 Spring Cutting Questions
05:49 When to apply energy cons & work energy theorem
06:21 1st Example (only energy cons)
07:50 2nd Example (now friction is also there)
12:33 3rd Example (block falling on spring)
15:13 4th Example (block falling block then spring compresses further)
20:49 5th Example (external force in action)
24:22 6th Example (velocity of COM also)
29:00 7th Example (reduced mass application)
32:01 8th Example (projectile mixed question)
