In theoretical mechanics textbook,the differential equation of the plane motion of rigid body is derived from the theorem of the motion of mass center combined with the moment of momentum theorem for the relative mass center.It provides a common method for solving the dynamic problem of plane motion of rigid body.But in some cases,the use of other forms of planar motion equation can be more efficient.In order to improve the efficiency of solving problem with the application of planar motion differential equation,the general form of the moment of momentum theorem of moving point are conducted.C...
