Abstract: The objective of such new demonstration and experimental device for measuring moment of inertia and angular momentum conservation is to improve the efficiency and accuracy of measuring moment of inertia. The experimental results show that the device has the advantages of simple measuring method, measuring speed, more accurate results. In addition,it has also a qualitative demonstration and quantitative validation for closed angular momentum conservation system and a number of experimental functions.

Key words: comparison method, moment of inertia, conservation of angular momentum, experimental device
