Physics - Mechanics - Momentum - Collisions (elastic and inelastic) - Bounce or Stick?
Students sort 10 collision scenarios into 'Elastic (Bouncy)' vs 'Inelastic (Sticky)'. Elastic: Pool balls colliding, Newton's cradle, bouncy ball on hard floor, air molecules colliding. Inelastic: Car crash (cars crumple), clay balls sticking, football caught by player, bullet embedding in block, tw
