Stopping Distances & Crash Hazards – physics lesson Pgh

Full PowerPoint and resources to teach a lesson on Stopping Distances and Crash Hazards. It covers how human reaction times are measured and recalling typical human reaction times, describing the link between stopping distance, thinking distance and braking distance and recalling the factors that affect stopping distances and describing how different factors affect stopping distances and factors that affect driver’s reaction time.  It also covers linking large decelerations with force and dangers in collisions, safety measures in vehicles and how they work plus calculating the force needed to produce a change in momentum.
