A Study On The Basis Of "Decomposition Of Force" In Physics Of High School

Physics of high school is an important part of the whole physics education,and it is also a basic course in the field of scientific research in ordinary high schools.It aims to further improve students' scientific literacy.The "power of the decomposition of" teaching as a high school physics in an important basic course,has long been faced with special difficulties.Through the relevant literature,the author finds that there is a questionable p lace in the expression of the content of "decomposition of force" in the current high school physics teaching material,that is,"the force is decomposed according to its actual effect".For this problem,the author puts forward the research of this subject under the guidance of the instructor,which aims to give the conclusion of our research from the angle of the methodology.It is hoped that this study will have a reference function for the writing of the textbook.Teaching and student learning can also be helpful.In this paper,the study of "power decomposition" is based on the theory of vector theory and classical mechanics,and Newton's law as the theoretical basis.First of all,this paper studies the source,meaning and representation of vector,and then makes a systematic study of the concept of force.The concept of force is the dialectical unity of its concrete reality and mathematical abstraction.Finally,the purpose,basis and logical steps of the decomposition of the theoretical foundation.Based on the research results of this thesis,the author makes a comparative analysis of the contents of the chapter on the decomposition of power in the existing middle school physics textbook,thus clarifies the teaching logic of "decomposition of power" and finally forms the "decomposition of power" O f the teaching case,the study of all the results of the practice and display.
