Abstract: High school student’s face difficulties and great challenges in dealing with problems and physical situations related to Newton’s laws in particular, this is due to the absence of a clear strategy. Most of the pupils and even some students fail in identifying the object studied (the system studied) the forces exerted, on which object are exerted and what nature are they. The main objective of this study is to provide a scientific method for students and teachers which allow them to address all physical situations in all cases, whether in school or professional lives.
