Then we were off.As the rocket rose into the air，we were pushed back into our seats because we were trying to escape the pull of the earths gravity.It was so hard that we could not say anything to each other.Gradually the weight lessened and I was able to talk to him.“Why is the spaceship not falling back to the earth？On the earth if I fall from a tree I will fall to the ground.” I asked.“We are too far from the earth now to feel its pull，” he explained，“so we feel as if there is no gravity at all.When we get closer to the moon，we shall feel its gravity pulling us，but it will not be as strong a pull as the earths.” I cheered up immediately and floated weightlessly around in our spaceship cabin watching the earth become smaller and the moon larger.When we got there，I wanted to explore immediately.“Come on，”I said.“If you are right，my weight will be less than on the earth because the moon is smaller and I will be able to move more freely.I might even grow taller if I stay here long enough.I shall certainly weigh less！”I laughed and climbed down the steps from the spaceship.But when I tried to step forward，I found I was carried twice as far as on the earth and fell over. “Oh dear，”I cried，“walking does need a bit of practice now that gravity has changed.”After a while I got the hang of it and we began to enjoy ourselves.Leaving the moons gravity was not as painful as leaving the earths.But returning to the earth was very frightening.We watched，amazed as fire broke out on the outside of the spaceship as the earths gravity increased.Again we were pushed hard into our seats as we came back to land.“That was very exhausting but very exciting too，” I said.“Now I know much more about gravity！Do you think we could visit some stars next time？” “Of course，” he smiled，“which star would you like to go to？”月球之旅月球之旅我我的的朋朋友友李李彦彦平平是是一一位位天天文文学学家家，上上个个月月我我有有幸幸得得到到一一个个机机会会同同他他一一起起去去太太空空旅旅行行。我我们乘乘宇宙宇宙飞船参船参观了月球！了月球！在启程以前，李彦平向我解在启程以前，李彦平向我解释说，在我，在我们的航的航行中会有三次引力的改行中会有三次引力的改变，而第一次的改，而第一次的改变将将是最是最强强的。随后我的。随后我们就启航了。随着火箭的升就启航了。随着火箭的升空，由于我空，由于我们在努力在努力挣脱地球的引力，我脱地球的引力，我们被被向后推在座位上。向后推在座位上。这种引力太种引力太强强了，以至于我了，以至于我们彼此彼此间都不能都不能说话了。随后，了。随后，这个力量慢慢减小，我才能个力量慢慢减小，我才能够同同他他讲话。我。我问道：道：“为什么太空船不会向后朝什么太空船不会向后朝地球的方向落下去呢？在地球上的地球的方向落下去呢？在地球上的时候，如果候，如果我从我从树上掉下来，上掉下来，总会朝地上落下去的。会朝地上落下去的。”李李彦平解彦平解释说：“现在我在我们离地球太离地球太远了，感了，感觉不到地球的拉力，所以我不到地球的拉力，所以我们感感觉好像没有地球好像没有地球引力了。引力了。当当我我们更更接接近近月月球球时，就就会会感感到到月月球球的的引引力力在在拉拉我我们。但但是是，月月球球的的引引力力不不像像地地球球的的引引力力那那么么大大。”我我立立刻刻感感到到很很高高兴，由由于于失失重重我我在在太太空空舱里里飘来来飘去去，我我望望着着(身身后后的的)地地球球越越来来越越小小，而而(前前方方的的)月月球球越越来来越越大大。我我们到到达达月月球球时，我我就就想想立立即即进行行探探测。“来来吧吧，”我我说，“要要是是你你讲得得对，我我的的重重量量就就会会比比在在地地球球上上小小，因因为月月亮亮比地球小，而我就能更自由地活比地球小，而我就能更自由地活动了。了。如如果果我我在在月月球球上上呆呆的的时间足足够长的的话，我我甚甚至至可可能能长得得更更高高，我我的的体体重重肯肯定定也也会会变得得更更轻！”我我笑笑着着从从飞船船的的梯梯级上上爬爬下下来来。而而当当我我试着着向向前前迈步步的的时候候，我我发觉我我被被送送出出去去很很远，步步子子的的跨跨度度竟竟是是在在地地球球上上的的两两倍倍，因因而而我我摔摔倒倒了了。“天天哪哪，”我我大大声声说，“重重力力改改变了了，看看来来走走路路也也的的确确需需要要练一一练了了。”过了了一一会会儿儿，我我才才掌掌握了走路的握了走路的诀窍，这才开始感到自如了。才开始感到自如了。摆脱月球引力不像摆脱地球引力那样痛苦。但摆脱月球引力不像摆脱地球引力那样痛苦。但是返回到地球的经历却是非常吓人的。我们惊是返回到地球的经历却是非常吓人的。我们惊奇地看着，随着地球引力的增加，宇宙飞船的奇地看着，随着地球引力的增加，宇宙飞船的外层燃烧起火。外层燃烧起火。 当我们回到地面时，我们又感当我们回到地面时，我们又感到被重重地推倒在座位上。我说道：到被重重地推倒在座位上。我说道：“真是精真是精疲力竭了，但也很激动人心。关于引力，我现疲力竭了，但也很激动人心。关于引力，我现在就懂得更多了。你认为下次我们可以上星球在就懂得更多了。你认为下次我们可以上星球上去参观吗？上去参观吗？”“当然可以，当然可以，”他笑着说，他笑着说，“你想到哪颗星球上去呢？你想到哪颗星球上去呢？”速效提能演练速效提能演练本部分内容讲解结束本部分内容讲解结束点此点此进入入课件目件目录按按ESC键退出全屏播放退出全屏播放谢谢使用使用
