旋转动能
Introduction
质心和延伸物体的动能值可以用旋转动能表示。线性动能和旋转动能都是基于功能原理以平行方式发展的。旋转动能的表示是基于物体旋转的特定轴来完成的。
Rotational Kinetic energy: Analysis
在物体旋转的过程中，会产生旋转能量。总动能的一个重要部分被称为旋转能。惯性矩发生在旋转能量基于物体的旋转单独发生的时候。角动能是另一个用来定义旋转能的术语（Cutting，Hindmarsh和Weir，2020）。物体旋转的一个相关且有目的的结果是其旋转能量。
Figure 1: Rotational kinetic energy
旋转动能和旋转惯性之间的关系在本质上是成比例的。幅度的平方也与角速度有关。旋转动能和平移能都存在于滚动物体中。
The formula of rotational kinetic energy
旋转物体及其旋转能量可以通过遵循一个重要的公式来测量。在数学上，这个公式可以表示为$mathrm{K_R:=：1/2:*I:ω^{2}.}$在这个公式中，$mathrm{K_R}$表示旋转动能的值（Liu等人，2018）。符号“I”表示惯性矩的值。这个公式中的ω表示角速度的值。
旋转动能是通过考虑惯性矩和角速度的计算乘积的一半来表示的。动能的线性形式和旋转形式都可以用这个表达式表示。功的原理与完成整个旋转所需的能量成正比。惯性矩和施加扭矩之间的平行性质与此相关（Zhao&；Tresp，2018）。作用在质量上的力用m表示。这是从前端和末端考虑的。
Relation of Newton s Second Law with rotational kinetic energy
牛顿第二定律的概念与旋转动能的基础是一体的。根据牛顿第二定律，加速度的值等于速度的合成值。速度的值要除以确切的时间量。
Figure 2: Rotational objective
`牛顿第二旋转定律很重要，因为角加速度的值是从中提取的。通过考虑最终速度的一半结果来提取平均速度值（Zhang等人，2020）。对象的旋转轴因对象而异。未附着的对象及其旋转轴围绕质心旋转。
Relevant units of rotational Kinetic Energy
旋转动能以国际单位制中的J（焦耳）表示。在MKS单位系统中，单位用$mathrm{kg.m^2.s^{-2}}$表示。在量纲动力学公式中，旋转动能值用表示。量纲公式也是一个重要的部分，可以用旋转动能的基本公式来表示。与惯性矩相关的尺寸公式等于$mathrm｛M^1L^2T^0｝$。角速度也与此相关（Ariska，Akhsan&；Zulherman，2018）。
其维数公式为$mathrm｛M^0L^0T^｛-1｝｝$。旋转动能的值可以通过减去角速度值和惯性矩的值来提取。这个减法的结果是$mathrm｛M^1L^2T^｛-2｝｝$。
Characteristics of rotational kinetic energy
动能比任何其他物体都重。旋转动能可以转化为其他类型的能量。速度和动能之间存在着显著的关系。这种关系在本质上是成比例的。发现动能随着物体速度的变化而增加和减少（Zhang等人2018）。旋转动能是用焦耳来测量和表示的。物体的方向与旋转动能整体相连。旋转动能的使用有助于当地用户使用正常的发电过程。

Conclusion
旋转动能可以在风车中找到，风车的叶片在风的作用下运动。风吹到叶片上，叶片旋转。叶片的这种运动有助于发电。在这个术语中，运动的空气具有动能。在这个过程中，动能被输出并转化为机械能。基于此，可以分析功和能量之间的关系。在引力和均匀圆周运动中，旋转动能也具有重要的影响。
