identifying students' weaknesses in circular motion and centralist force and acceleration analysis

in high school, some topics in physics are conceptual, and there are many uses for them in the environment. in teaching, these concepts show that students have weaknesses. therefore teachers face difficulties in the process of education. to address such educational weaknesses, identifying them is the first step. the topic of uniform circular motion in the twelfth of mathematics is one of the most important topics in dynamics. since this type of movement is done indirectly, it is impossible for students to make mistakes. the purpose of this study was to identify 12th grade math students in shahid fakouri school district 14, tehran, to identify some of their weaknesses in uniform circular motion and centralist force and acceleration analysis. data gathering tool is a weakness identification questionnaire. the obtained data have been are qualitatively analyzed, and the results show that students have problems in recognize the type of movement from a cinematic point of view identifying the force as the driving force from a dynamic point of view. circular motion imaging for students in the teaching process,without the use of teaching tools,has increase the likelihood of misunderstanding in detecting force and analyzing centripetal acceleration and velocity in uniform circular motion.
