在人教版高中物理新课标必修2中引入“探究功与速度变化的关系”实验,通过实验探究原来静止的物体做的功与物体获得的速度的关系,目的是为了让学生经历和体验探究的过程,提高理论联系实际的水平,为下一节“动能和动能定理”的理论推导奠定认知基础。通过该内容的教学,也可以促使学生在学习动能定理后能比较深刻地认识到动能定理不
In PEP Physics High School Physics Compulsory 2 introduced “to explore the relationship between power and speed changes” experiment, through experiments to explore the original static object to do with the object speed and the relationship between the speed, the purpose is to allow students to experience And experiencing the process of inquiry, raising the level of the connection between theory and practice, laying a cognitive foundation for the theoretical derivation of the theorem of kinetic energy and kinetic energy in the next section. Through the teaching of the content, students can also be prompted to learn kinetic theorems can be more profound understanding of kinetic energy theorem
