借助数学方法探究一道似是而非的物理问题

Exploring a Plausible Physical Question with the Help of Mathematical Methods

针对在教学中遇到的一道与斜面摩擦力相关的改编习题,借助数学方法,进行了深入细致的探究,利用数值分析,讨论了动摩擦因数对物体运动状态的影响.整个探究过程,不仅体现了数学方法与物理思维的互相融合,而且对教师在教学及命题方面具有很好的启发.

This paper exploredan exercise related to friction force on inclined plane encountered in teaching deeply and detailly using mathematical methods,and discussed the influence of dynamic friction factors on the motion state of objects by numerical analysis.The whole exploration process not only reflected the integration of mathematical methods and physical thinking,but also had a good inspiration for teachers in teaching and proposition.
