| Abstract: | To show the conversion relationship between covariant polar coordinates and inverse polar coordinates as well as the conversion relationship between the two systems and descartes coordinates by using matrix is called polar coordinates matrix method. By using this method, obtained the specific forms in polar coordinates of frequently-used physical quantity of the particle kinematics and particle dynamics along with the conversion relationship of its specific forms in descartes coordinates, and gave the corresponding numerical example. |
