| Abstract: | The dissertation discusses the symmetry principle within the domain of macroscopic classical mechandics. attempting to deduce the law of conservation of mechanical energy from the invariane property in time translation,the law of mementum from the invariance property in space translation and the law of conservation of argular momentum from the invariance property in space rotation. |
| Keywords: | symmetry invariance property in time translation invariance property in space translation invariance property in space rotation |
