Abstract: 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.

Key words: parabolic motion, momentum conservation, experimental design, transformation method
