对北半球地球表面竖直上抛的物体受科里奥利力的作用而产生的运动轨迹的变化作了全面的分析,给出了不考虑空气阻力情况下竖直上抛运动的近似解和精确解,进一步得出考虑空气阻力情况下竖直上抛运动的近似解,最后通过Fortran编程对上述3种情况的运动进行了数值模拟,明确指出竖直上抛的物体在上升阶段和下落阶段都偏西的运动规律. A comprehensive analysis is made on the change of trajectory caused by the effect of Coriolis force on the objects thrown upright on the surface of the Earth in the northern hemisphere. An approximate solution and an exact solution of the vertical upward throwing motion without air resistance are given Solution, the approximate solution to the vertical throwing motion considering air resistance is obtained. Finally, Fortran programming is used to numerically simulate the motion of the above three cases, and it is clearly pointed out that the objects thrown up vertically are in the rising phase and the falling phase West of the law of movement.
