基于平抛运动验证动量守恒的实验装置

Experimental Design for Verifying Momentum Conservation Based on Flat Throwing Motion

为了直观的验证动量守恒定律,设计了一种基于平抛运动验证动量守恒的实验装置,与传统的实验装置相比,该设计利用转换法将不易直接测量的速度物理量转化为长度物理量的测量,对提高教学效果以及提高学生的物理学科核心素养有着十分重要的作用。实验装置的制作简单、演示方便、现象直观、坚实耐用,便于自制和推广。

In order to verify the law of conservation of momentum intuitively,an experimental instrument for verifying conservation of momentum is designed based on parabolic motion.Compared with the traditional experimental design,the design uses the conversion method to convert the velocity physical quantity that is not easy to measure directly into the measurement of the length physical quantity,which plays an very important role in improving the teaching effect and the core quality of the students'physics disciplines.The experimental device is simple in making,convenient in demonstrating,intuitive in phenomena,solid,durable,easy to make and suitable to popularize.
