conservation of energy theorem的意思|示意

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。

Recent trends in the Lagrange equation's conversion and form from inertial system to non-inertial system, the application of energy theorem, energy conservation law, etc. are introduced.

介绍了在非惯性系中建立动力学方程的方法，惯性系中拉格朗日方程在非惯性系中的转换形式，以及非惯性系中的能量定理和能量守恒定律的应用等研究成果。

To use respectively that rigid body plane differential equations of motion, theorem of angular momentum, conservation law of mechanical energy, and the law of conservation of energy.

从时间的均匀性可推得机械能守恒定律，从空间的均匀性和空间的各向同性可分别推出动量守恒定律和角动量守恒定律。
