第三宇宙速度之小议

The Discussion of the Third Cosmic Velocity

第三宇宙速度是从地球上抛出物体使其能逃离太阳吸引的最小速度,本文主要以机械能守恒定律为基础介绍了第三宇宙速度的计算方法,以供教学中作为参考。

The third cosmic velocity is the minimum velocity that you throw an object and let it escape from the universal gravitational force of the son. In this article,introduce the calculate method of the third cosmic velocity at the basic of conservation of mechanical,it can be for your reference at the teaching.
