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。

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

这是曲线的终点。

That's the endpoint of my curve.

如果曲线c，起点为P0，终点为1，那么计算所做功的线积分，只与端点位置有关，而与我们选择的路径无关。

P1 If we have a curve c, from a point p0 to a point p1 then the line integral for work depends only on the end points and not on the actual path we chose.
