| 摘 要： | 从牛顿定律出发,利用数值算法计算研究了初始高度处于大气层中不同位置的自由落体的落地速度.计算中,重力加速度分别取为重力加速度常数和随高度而变的变重力加速度,并将计算结果进行比较,从而得出将重力加速度视为常数的合理的高度范围.

| Abstract: | By means of numerical algorithm,the fall velocity of the free falling body,which is set at different heights of atmosphere,is calculated according to Newton's law of motion.In our calculation,the variant and constant accelerations of gravity are respectively used and their results are compared to obtain the rational range of height with the acceleration of gravity defined as constant. |
