conservation of energy theorem 能量守恒定律 ; 能量守恒定理
I used first the conservation - of mechanical energy — there was no friction — and then I showed you that it's completely consistent with the work-energy theorem, so what would you do now?
首先，我用了机械能，守恒定律-，这里没有摩擦力-，我会向你们展示，这，和功能定理完全一致，现在你会怎么做呢？
And so you could have used the work-energy theorem or you can use the conservation of mechanical energy.
所以你也可以用，功能定理，或者是机械能，守恒定律。
