| Abstract: | 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. |
