摘要
空气阻力对抛射体的运动产生显著影响,在低速抛射情况下,通常有空气阻力与速度一次方成正比和与速度平方成正比两种模型;在得出两种模型的抛射体轨迹方程精确解基础上,应用Scilab软件在相同抛射速度和角度下,对两种模型的轨迹和射程进行了对比。
Air friction poses a notable effect on the motion of projectiles. In low speed circumstances, there are ordinarily two kinds of air friction resistance models. In one model, the air resistance is proportional to the velocity of projectiles, while in the other, it is proportional to the square of the velocity. The analytic governing motion equations of the projectiles under the two models were deduced. By the aid of Scilab software, the two models were compared under some conditions. The two equations will certainly be helpful to the engineering application.
