人教版高中《物理》第一册(必修加选修)第五章曲线运动第二节“运动的合成和分解”安排了一个演示实验,用这个实验定性说明合运动是分运动合成的结果.笔者在教学中用J2170运动合成演示器实验取得了较好教学效果.现说明如下:
PEP High School “Physics” Volume 1 (required plus optional) Chapter 5 Curve Movement Section 2 “Synthesis and Decomposition of Exercises” A demonstration experiment was arranged to use this experiment to qualitatively explain that the combined exercise is composed of sub-sports Results. The author used the J2170 motion synthesis demonstrator experiment to achieve better teaching results in teaching. The explanation is as follows:
