I now go into an elliptical orbit because the new velocity is no longer the right velocity for a circular orbit.

我现在要进入一个椭圆形轨道，因为新的速度已经，不是圆形轨道中的速度。

Also that velocity, v, in that equation number five will also change with time because it's an elliptical orbit.

同样的，第五个方程序，中的速度同样，会随时间改变，因为这是椭圆形轨道。

The rectilinear movement has thus become changed into a circular motion of extreme velocity, and it is now pursuing an elliptical orbit round the moon, of which it has become a true satellite.

因此，炮弹由直线运动变成高速的环形运动，现在正沿一条椭圆形轨道绕着月亮飞行，变成了一颗真正意义上的卫星。
