抛射体

抛射体的竖直方向和水平方向的运动能够分开来处理。

The vertical and horizontal motions of a projectile can be treated independently .

月球在什么时候出现在抛射体最容易击中的位置上？

在忽略空气阻力的情况下，抛射体运动的飞行路径长度与抛射初速度的平方成正比；

The length of flight path is proportional to the square of initial ejection velocity when the resistance of the air is ignored .

在地面附近的抛射体偏离发射面的情况是与发射仰角α和发射声、的纬度λ有关系。

The condition that projectile near the ground deviates from the launching plane is concerned in the launching angle of elevation a and the latitude of launching point λ .

能够产生如此庞大的巨坑，早期的那次撞击必定是空前绝后的，据计算撞击的抛射体体积比冥王星还要大。

To have produced such a large crater , the ancient impact must have been absolutely otherworldly , with the offending projectile calculated to have been larger than Pluto .

抛射体变得更加重要，因为人们已能用大炮把炮弹射到几百码的距离之外。不要进入他们大炮的射程以内，要隔一段距离包围住敌营。

Projectiles became more important because cannons could now fire balls over hundreds or yards . Don 't get within range of their big guns ; surround the camp from a distance .
