摘要
力学是物理学的基础与核心,主要研究物体的机械运动规律。在力学中,对物体进行受力分析进而建立动力学方程是研究机械运动规律的关键。本文利用定滑轮、测力计、PVC演示板、钩码、刻度尺、量角器等原材料设计并制作了力的合成与分解演示实验仪器,并对演示仪进行了推广与演示,在教学中取得了良好的教学效果。
Mechanics is the foundation for physics,mainly studying the mechanical motion of objects.In mechanics,the analysis of force and motion is the most basic and critical part.In the present work,the demonstration instrument for resultant and component of forces is designed and fabricated,using the fixed pulleys,forcemeter,smart PVC demonstration board,hook codes and other materials.The demonstration instrument is popular among high school students,resulting in satisfactory teaching effects in teaching.
