摘要
用物体与气体分子碰撞模型来分析物体的收尾速度以及所受空气阻力.假设在未达到收尾速度前物体加速度是均匀递减的,根据这一假设,建立物体在达到收尾速度之前的运动方程.
By the falling body with the gas molecular collision model, the resistance of a falling body is received, and the extreme speed of the falling body is analyzed. It is proposed that when not achieving before the extreme speed of the falling body, the supposition of a falling body acceleration is evenly decreasing. According to this supposition and uses the falling body extreme speed obtained,the author analyses that the falling body movement in has not achieved before the extreme speed.
