Um mapa conceitual para interações fundamentais

Resumen

At first, the paper stresses a modern trend concerning the curriculum of high school and introductory college physics courses. According to this trend, the curriculum must be modernized by the introduction of contemporary physics topics and by teaching traditional classical physics tapies from a modern point of view. Following this trend, a concept map for fundamental interactions of nature is presented focusing the topic "forces" from a unifying standpoint showing that the number of fundamental forces of nature is actually quite small. Finally, the question of contextual dependence of the meanings assigned to physical concepts is also discussed.
