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
