The definition of power and energy and the kinetic energy theorem are important concepts and laws in physics. In the process of compiling textbooks, how to present these concepts and laws to students and how to describe them scientifically are important issues that should be worth exploring. The concept of work and kinetic energy is presented in the first book of “The Outline of Physical Education” (Compulsory), a full-time high school textbook written by the People’s Education Publishing House.
