在天体运动与万有引力中,关于人造卫星的发射、运行与变轨问题都是非常典型热点问题.本文讨论人造卫星在地面上如何发射才最容易、最节能.首先来讨论和理解人造地球卫星的第一宇宙速度.图1根据牛顿抛物运动原理图1知,从高山顶A以不同速度V水平抛出的物体,由于受到地球对它的引力使其飞行路线发生弯曲而落回到地面上.当水平抛出物体的速度越大时,物体在地面上的落点离开山脚越远;如果没有空气阻力,当物体的水平抛出速度
In celestial movement and gravitation, the launch, operation and orbit change of satellite is a typical hot issue.This article discusses how to launch artificial satellite on the ground is the easiest and most energy-efficient.First, to discuss and understand the artificial earth satellite First Universe Velocity Figure 1 According to the Newton’s parabolic motion principle, an object thrown at a high velocity V from high summit A falls back to the ground due to the earth’s gravitational pull that causes it to curl its flight path. When the object is thrown at a higher level, the farther the object falls from the foothill on the ground. If there is no air resistance, when the object’s horizontal throw speed
