There are also a great way to think about actually any curve, any trajectory that can be traced by a moving point.

当然还有其他的描述动点形成的曲线，或者轨迹的办法。

But the curve trajectory isn't as steep as Carlson might like.

但是曲线轨道并不像Carlson希望的那样陡峭。

So as a ball slows down at the end of its trajectory, the curve becomes more pronounced.

所以当球运行到终点时，由于速度下降，将会划出更明显的曲线。
