我们相信,机械能守恒定理。

We believe in the conservation of mechanical energy.

youdao

现在我想回到，机械能守恒。

Now I want to return to the conservation of mechanical energy.

youdao

我百分百相信，机械能守恒。

I trust the conservation of mechanical energy 100%.

youdao

因此这是，机械能守恒。

So this is the conservation of mechanical energy.

youdao

肯定有什么，基础性的错误，这个机械能守恒定理。

There must be something fundamentally wrong with the conservation of mechanical energy.

youdao

记住这个，我们能够很放心地,使用机械能守恒定理。

So with this in mind, I feel comfortable to pursue my conservation of mechanical energy.

youdao

大声点。，lewin：，So, speak, up。，我们可以尝试用，机械能守恒定律吗？，这样用有什么问题吗？

LEWIN Shall we try the conservation of mechanical energy Is there anything wrong with that?
