Resumen
Collision studies conducted with low-friction dynamics carts equipped with Bluetooth motion encoders produce very clean velocity–time data. This technology makes it possible for students to analyze collisions to determine which collision types illustrate the laws of conservation of momentum and energy. Physics instructors often include the study of completely inelastic collisions and elastic collisions in their lab classes. Adding a study of the common inelastic collision and the more complex superelastic collision will give students experience with the four fundamental collision categories. Rather than rely on teachers to inform students in which situations the laws of conservation of momentum and energy apply, learners can now collect reliable collision data and formulate their own conclusions.
