Using State records about vehiculular deaths, accident investigations and classroom and community 'Labs' using wireless data recorders from Vernier Software to demonstrate the effects of speed, mass, momentum (conservation), energy(conservation) and collisions (elastic vs inelastic)in an accident. We will deal with fact or fiction ('myth busting') concerning speed and size. Should I accelerate before a crash? Wearing a seat belt really help and the use of helmets to name a few.
