The aim of the research is the concurrent record of the teachers’ perceptions of different disciplines, types of schools and levels of education, and to explore how fundamental concepts and laws of physics are approached. The survey involved 253 primary and secondary, both general and technological, education teachers from different disciplines. They responded to twelve True/False questions that referred to fundamental concepts and laws of Physics and focused on the conceptual understanding of the physics of everyday life. Teachers' performance reaches the high level of international research. The answers provided seem to be influenced by the description of the situation in the wording of the task as well as by the intuitive experiences of everyday life, resulting, in many cases, in responding based on the result of the actions rather than the laws of physics.
