经典力学问題

October 13, 2017 by

这个自然,一对静摩擦作用力与反作用力做的总功恒为零,因为这一对力的相应作用点无相对位移,再者刚体的内力又不做功,故以上因素都不会引起体系总动能的增加;但体系通常还有其他保守力做功(如沿斜面下滚的轮子,重力对其做功),所以一般情况是机械能守恒,而非你帖子标题所言的“动能守恒”。

轮子沿水平地面滚动时,重力不做功,便有动能守恒,不过,此时静摩擦力为零(换句话说,即使是光滑的地面,只要初始时纯滚动,这一状态照样能保持)。

无论是数学生物还是物理,实验技巧虽不及chemisty, there is something common in understanding the apparatus used in these disciplines. 而apparatus是指:

Hurricane, stormy weather and longing

Besides stress I still feel a little down more than before. I keep a good attitude toward to the subject I am teaching. By focusing on the problems and issues I faced. Some of them are minor issues.

Middle age crisis and love

September 27, 2017 by

When I arrive at this school, I am half the way to the my middle age. I am puzzled by my lost contact with old friends and reality. Traditionally I am a very goal-oriented person and know what I want and I don’t. But not this time. I met this guy who is younger than me and knew more than me. He is very good looking and friendly with most people I knew. I cannot find a shortcoming or anything negative about him since I became picky these days. I really confused with this friendly love with other things.

The art of teaching

How to teach physics in English? I started it in a private school in Beijing. Students are motivated to learn but not quick enough. It is just the knowledge which is too dry. How to make teaching and learning interesting is still the unresolved question. Language speaking, they are not native speakers. Both knowledge and language skills are in need of development.
Still go back to square one about what is physics. physics is to understand the nature and the world. Then we use physics to explain everything from tiny atoms to the planets.
