| Abstract: | A form invariance of Nielsen equation of nonconservative mechanical system is studied. The definition and criterion of the form invariance of Nielsen equation of a nonconservative mechanical system are given. The relation between the form invariance and the Noether symmetry is studied. Some examples are given to illustrate the application of the result. |
| Keywords: | nonconservative mechanical system form invariance Nielsen equation Noether symmetry |
