Research On Teaching Of The Concept Of Potential Energy In Senior High School

Physics textbook for senior high school in writing conception of potential energy is through the analysis of a single force acting on a construction of the concept of the potential energy, which neglected the conservatism of the single force will be with reference changes, when the particle system and the construction of the concept of the potential energy of the force associated with conservative changes and potential energy concept is no longer applicable to the particle system. Through systematic study of potential energy related knowledge, and points out that the introduction of potential energy in the system of particles must be investigated a pair of force and counterforce bombe and potential energy variation, a pair of acting force and counterforce total work and the frame of reference is independent of the choice, the pair of action and reaction force acting on the analysis of any inertial reference frame are established to construct the concept of the potential energy of the, only seize this point to various definitions of the concept of the potential energy is reasonable, in order to eliminate the textbook compilation of existing problems. On the basis of fully studying the relevant knowledge of potential energy, this paper makes a systematic analysis of the current high school physics textbook, points out the shortages of the textbook compilation and puts forward some suggestions for the revision of the individual.
