1. Momentum Basics
10 minutesDefine momentum as p = mv, practice calculating momentum for single objects, and build intuition for why both mass and velocity matter. Use everyday examples like trucks vs. bicycles.

2. Conservation Principle
15 minutesEstablish that total momentum is conserved in closed systems. Analyze simple before-and-after scenarios: push-offs from rest, recoil problems, and identify when external forces break conservation.
3. Collision Types
20 minutesDistinguish elastic from inelastic from perfectly inelastic collisions. Solve 1D collision problems using momentum conservation, and check kinetic energy to classify collision type.
4. Impulse and Force
15 minutesConnect force, time, and momentum change through the impulse-momentum theorem. Analyze real-world safety applications: airbags, crumple zones, catching techniques.
5. Advanced Applications
20 minutesTackle 2D collisions, explosions with multiple fragments, continuous-mass problems (rockets, fire hoses), and the ballistic pendulum. Integrate momentum with energy conservation.
