University Physics Teaching Classical Physics Research And Its Teaching Significance

In this paper, on the current states of research the electrical field of the charged body and the rotational inertia of uniformed body are firstly reviewed and then lucubrated. The electrical field of uniform charged ring is obtained by use of two ways, one is using the electrical field equation of point charge and the superposition principle to get exact results of the electrical field and potential presented by elliptic functions, the other is solving the Laplace equation to get the series solutions of the electrical field and potential. The rotational inertia of some uniformed bodies is obtained without doing integral. At last, how to cultivate students' exploring ability and research ability is briefly discussed bases on the modern teaching theory and self-study experience.
