  3. Energy • Conservation of Linear Momentum • Collision • Cars crashing • Projectile Motion • Ball projected from domino into funnel • Conservation of Energy • Rotational Kinetic Energy • Ball rolling down hill • Center of Mass • Wood piece balancing on nail

  4. Budget Time Item • Domino’s • Tubing • Marbles • Boxes • Wood • Cars • Steel • Funnel • Light system • Nails TOTAL Cost $ 0.50 2.00 1.00 5.00 2.50 1.00 2.00 0.75 4.00 0.50 19.25
