Abstract: A multi-functional demonstrating instrument of angular momentum theorem is intoduced,which is simple in structure and convenient for operating.The instrument demonstrates the related experiments of angular momentum theorem and illustrates the physical laws of the rigid-body fixed-point rotation,which is inspiring.In addition,it has the function of analyzing the experimental phenomenon with the angular momentum theorem in the natural coordinate.

Key words: torque, angular momentum theorem, demonstrating instrument, natural coordinate
