在初中物理《运动和力》一章的教学中,二力平衡知识是解决许多力学问题的重要依据。如果在教学中能使学生对这一问题理解得更加透彻,就能使学生在实际分析中更加灵活地运用二力平衡知识做出许多巧妙的分析,从而提高学生的灵活运用能力,增进学生的学习成就感,为进一步培养学生的想象力和创造能力打下良好的基础。但是,教
In the teaching of junior high school physics “sports and force”, the balance of knowledge between two forces is an important basis for solving many mechanical problems. If students can understand the problem more thoroughly in teaching, they can make students more flexible in the actual analysis to make many ingenious analyses by using the two forces to balance knowledge, so as to improve the student’s flexible use of skills and enhance students’ Learning a sense of accomplishment lays a good foundation for further cultivating students’ imagination and creativity. However, teaching
