In the high school level, science subjects, physics is relatively difficult subject learning physical Compulsory difficulties for many reasons. Learning psychological barriers, thought disorder, with mobility impairments. In this paper, student learning to compulsory a difficult factor as a starting point to explore the reasons for the difficulties students learn mechanics. In this paper, the survey method, literature review, observation research. This may indicate that the causes of difficulties in learning mechanics about three points:First, the students’ cognitive bias, the second is about teaching quality is low, the external environment misleading. These defects so that students there is a lot of difficulties to accept new knowledge, apply new knowledge.Under the guidance of the constructivist theory and the theory of cognitive development, this paper presents the following points coping strategies:strengthen student learning mechanics initiative, Second, to strengthen the professionalism of teachers, enhance students’ correct understanding of social phenomena. Mechanics is the key to learning physics and mechanics is the key difficulties in teaching students to be able to recognize the first cornerstone of physics. Force is a very abstract thing, so to learn the mechanics, the students need to have a certain abstract thinking ability. Students need to overcome negative thinking to set, to improve the resilience of Aesthetic it be possible to improve the results of the physical and mechanical.Finally, teaching practice, has been the demonstration, teaching practice, the teaching strategies with a certain degree of operability and feasibility.
