摘　　要：力分解式动量方程实验仪采用分体垂直射流机构、受力机构和测力机构的架构设计,规避了水平射流产生的原始误差,在保留原有实验特色下,增加了动量的定性与定量分析,并且将动量中的力拓展到力的合成与分解,能生动展现力的三角形法则和牛顿三大定律,将抽象物理概念形象、具体化,丰富了动量方程实验教学内容,增强了实验的创新性和趣味性。By adopting the structure design of split vertical jet mechanism, force-bearing mechanism and force-measuring mechanism, the experimental instruments for the force decomposition momentum equation can avoid the original error caused by horizontal jet. With the original experimental characteristics retained, qualitative and quantitative analysis of momentum is added, and the force in momentum is extended to the synthesis and decomposition of forces. The triangle law and Newton’s three laws of dynamic force are presented, and the visualization of abstract physical concepts enriches the content of momentum equation experiment teaching and enhances the innovation and interest of the experiment.
