我把物体放，在斜面上，增加倾斜角度，直到开始下滑。

So we're going to put a particular object on that incline and I'm first going to raise the Angle until it breaks loose.

在平行于放置被摄物体的位置上把有距离标尺的测试图表放置于一个斜面上。

Next to the parallel target, a patterned chart with a distance scale is placed on an incline.

和之前一样，还是把物体放在斜面上，这次不单独拿上来，我要把它和细绳相连。

I'm going to put an object now on an incline again, as we did before and instead of having it sit on its own I'm going to attach to it a string.
