摘　　要：验证动量守恒定律实验中要求两个滑块的水平初速度相差较大,上述要求对学生来说操作难度较大,本实验设计的装置是利用单摆击打滑块,使滑块获得相差较大的水平初速度,解决了操作难度大的问题,并且减小了实验误差.The conservation of momentum experiment requires two sliding block which have large difference of initial velocity,but it is relatively difficult for the students,this paper puts forward using pendulum struck the slider to solve this problem,and reduce the experimental error.

关 键 词：验证动量守恒 教学 改进
