Note :
The kinetic energy of a body is the energy it has in virtue of being in motion .
It is measured by one half of the product of the mass of each element of the body multiplied by the square of the velocity of the element ,
relative to some given body or point .
The available kinetic energy of a material system unconnected with any other system is that energy which is due to the motions of the parts of the system relative to its center of mass .
The potential energy of a body or system is that energy which is not kinetic ;
--
energy due to configuration .
Kinetic energy is sometimes called actual energy .
Kinetic energy is exemplified in the vis viva of moving bodies ,
in heat ,
electric currents ,
etc .;
potential energy ,
in a bent spring ,
or a body suspended a given distance above the earth and acted on by gravity .

covariance(协变)和 correlation(相关性)如何理解他们的区别? - 知乎 Correlation 存在的意义,则是将类似“10万”的数值概念相对化—— 考虑到 Portfolio 投资总额为1,000万,那么其潜在风险为1%(相对值),这对于多数投资者来说都处在一个可以接受的区间。
如何理解皮尔逊相关系数(Pearson Correlation Coefficient)? Pearson相关性系数(Pearson Correlation) 是衡量向量相似度的一种方法。 输出范围为-1到+1, 0代表无相关性,负值为负相关,正值为正相关。
相干性 (coherence )和相关性 (correlation) 有什么区别和联系? 相关性 (Correlation,或称 相关系数 或 关联系数),显示两相关变量之间线性关系的强度和方向。在统计学中,相关的意义是用来衡量两个变量相对于其相互独立的距离。而 相干性 (Coherence), 与相关性计算得到的信息非常相似,都是衡量两个变量之间的相关程度,只是 相干性 多用于 频域计算
如何理解皮尔逊相关系数(Pearson Correlation Coefficient)? Pearson 相关系数 (Pearson Correlation Coefficient,常简称 PCC,非 “Person 相关系数”),它是统计学中衡量 两个连续变量之间线性相关强度与方向 的经典指标,由英国统计学家卡尔・皮尔逊(Karl Pearson)提出,全称为 “皮尔逊积矩相关系数”(Pearson Product-Moment
相关系数和R方的关系是什么? - 知乎 维基百科Coefficient of determination(也就是R方)有明确的解释: “ In linear least squares multiple regression with an estimated intercept term, R^2 equals the square of the Pearson correlation coefficient between the observed y and modeled (predicted) f data values of the dependent variable ”

pearson 和spearman的区别是什么? - 知乎 用 A comparison of the Pearson and Spearman correlation methods - Minitab Express s解释可以很好理解: 根据这张图,我们可以看出: ①Pearson和Spearman相关系数的范围可以从-1到+1。 当Pearson相关系数为+1时,意味着当一个变量增加时,另一个变量增量相同。 这形成了一种递增的直线。
相关系数有什么意义,为什么说不能体现相关的程度? - 知乎 其实我统计学学得很渣,按我的理解来说说好了。 (很奇怪,在我本机上知乎的公式图片要翻墙才可见) 相关系数是建立在线性相关的基础上么? 根据维基百科的定义: 相关 (Correlation,或称 相关系数 或 关联系数),显示两个 随机变量 之间线性关系的强度和方向。在统计学中,相关的意义是
