- Rediscussing on the Force-Power equivalence
- in English and Chinese Keying Guan Department of Mathematics, School of Science, Beijing Jiaotong University Email: keying.guan@gmail.com Abstract: This paper will further accurately describe the equivalence relationship between force and power, point out that Einstein ...
- Supplementary Explanation on "Force-Power Equivalence“
- 关于“力-功率等价”的补充说明 （in English and Chinese） Since the author recently published two blog posts https://blog.sciencenet.cn/home.php?mod=spaceuid=553379do=blogid=1295413 and https://blog.sciencenet.cn/home.php?mod=spaceuid=553379do=blogid=1345496 It has ...
- Force is equivalent to Power
- Keying Guan Department of Mathematics, School of Science, Beijing Jiaotong University Email: keying.guan@gmail.com Just as Einstein demonstrated that mass equivalent to energy, force is equivalent to power . This is implicit in modern analytical mechanics and revealed in the autho ...
- 没有不做功的力--马德堡半球实验、举重运动消耗的卡路里及辐射压公式
- 管克英 北京交通大学理学院，数学系 Email：keying.guan@gmail.com Abstract: This paper points out that the combination of the law of conservation of energy and the law of conservation of momentum implies an important law that is often ign ...
- Relativistic elastic collision of two particles in 2D
- Guan Keying Department of Mathematics, School of Science, Beijing Jiaotong University Email: keying.guan@gmail.com Abstract: Under the framework of special relativity, this paper considers a basic problem of two-dimensional elastic collision, that is, i ...
- Light pressure fog caused by Maxwell-Bartoli formula
- Guan Keying Department of Mathematics, School of Science, Beijing Jiaotong University Email: keying.guan@gmail.com Abstract: It is proven that the so-called radiation pressure defined by the Maxwell-Bartoli formula is not mechanical pressure at all, causing confusion in d ...
- Maxwell的重要贡献，光压迷雾及光与普通物质相互作用的一个普遍规律
- 热度 1
- 管克英 北京交通大学，理学院数学系 Email： keying.guan@gmail.com 摘要：Maxwell 1873 年的一个关于太阳光压问题的计算思路其实有重要意义，当时却将计算结果错误地解读为光压。作者证明 Maxwell-Bartoli 公式定义的所谓辐射压强根本不是力学的压强，由此造成了物理学的量纲混乱，负面影响至今。 除此 ...
