 Starting from the simplified mechanical model of the earth-moon system,the dynamic

equations of the surface object in different coordinate systems are derived strictly,and through

the analysis of symmetry,the tid- al force is obtained,which is helpful to understanding of the

tidal force and the cause of tide.

Key words: tide, moon, tidal force, symmetry
