首先由第一题的结论可以知道滑动的盒子在底端的速度最快,因为潜在能量损失( MgH )完全转化为盒子的平动动能。 速度最快可以推导出下落时间最快吗?答案是可以的,试想在每下落一个极小的斜面,滑动的盒子速度都大于另外几个滚动的东西,所以最后下落的时间一定是最少的。 对于滚动的来说,列方程 MgH=\frac12Mv^2...

Well, the big takeaways about rotational motion are that: 1) It has mathematical analogs in the world of linear or translational motion that make studying either one in the context of the other extremely useful, as it shows how physics itself is "set up"; and 2) the thing...
The rotary encoder is a rotational version of a motion detector. As the encoder rotates, its angular position is measured and displayed as a graph of angular position vs. time. In constructing the angular position vs. time graph, the orientation of the encoder when the LabPro first begins co...
The total moment of inertia is the sum of moments of inertia of the merry-go-round and the child (about the same axis). To justify this sum to yourself, examine the definition ofI: I= 28.13 kg ⋅ m2+ 56.25 kg ⋅ m2= 84.38 kg ⋅ m2. ...
