Problems of optimization in natural science, technology, economics, and management are of great interest. Students also usually find them intriguing. However, the selection of such problems in introductory undegraduate physics textbooks is very limited and should be broadened. To that end, a model of traffic flow optimization, simple enough for…

What if you could challenge your 12th graders to understand car crashes in the context of physical forces, manufacturing challenges, government safety standards, and individual rights? With this volume in the "STEM Road Map Curriculum Series," you can! "Car Crashes" outlines a journey that will steer your students toward…

In this article we present the fascinating reconstruction of an accident where a car hit a boy riding his bicycle. The boy dramatically flew several metres through the air after the collision and was injured, but made a swift and complete recovery from the accident with no long-term after-effects. Students are challenged to determine the speed of…

Explains the variables involved when stopping a car on various types of pavement, braking schemes and additional concerns. (RT)

Describes the physics of what happens when a single vehicle rolls over on its side during the process of turning in an arc. (JRH)

Examines whether young children hold naive conceptions of speed and whether the nature of their concepts could be a causal factor in pedestrian accidents. Finds that children hold a range of beliefs regarding the concept of speed that would place them at risk. (Author/YP)
