Two different points of view in analyzing problems in mechanics The Eulerian view(欧拉观点) and the Lagrangian view(拉格朗日观点) Flow classification Streamline(流线)Pathline(迹线)& Flowfield (流场)流线方程计算流谱 Surface force(表面力) and body force(质量力,体积力)
accelerations account for non-central forces(drag, thrust, etc. X-axis in zenith, y-axis in frames velocity, and z-axis in transverse directions 8 Free orbit solution where 'A and 'B' are lengths and'a andB are phase angles
