2. Conservation of Angular Momentum

Learning outcomes
  • I can state the principle of conservation of angular momentum.
  • I can explain why angular momentum is conserved.
  • I can analyze systems with changing moment of inertia.
  • I can predict outcomes using conservation principles.
  • I can solve conservation problems involving rotation

Key Topics:
  • Law of conservation: ΔL=0 in the absence of external torques.
  • Examples: Ice skaters spinning, collapsing stars, gyroscopes.
