摘要
空气阻力和地球自转对抛体的运动皆会产生影响。分析了只考虑空气阻力和只考虑地球自转因素下的)体运动;并用Matlab工具绘图比较在不同参数影响下的射程变化趋势;推导了在地球自转和空气阻力共同影响下的)体运动运动学方程。
Air resistance and rotation of earth have a certain influence on projectile movement. In this paper, projectile movement is analyzed in only considering air resistance or rotation of earth. The trend of firing range in different parameter situations is expressed by using Matlab software. Then, the kinematical equation of projectile movement has been deduced under the influence of both air resistance and rotation of earth.
