中文方面，力矩又可以稱為“力距”或者“轉距”。
咁係因為力矩同“力與支點o既距離”有關：而佢會令到物體“轉動”。

引用:

力矩的定義：
力矩 = 力 x 力與支點的垂直距離

由此，力距唔係單單睇距離，重要睇力

批評好，批到體無完膚係尋找直理o既必經之道，critical thinking(批判性思考) 亞豬亞狗都聽過，其定義包括 criticism(批評)，只要唔係批人就可以，有圖有真相

What Critical Thinking is not:

Critical thinking is often confused with criticism, yet criticism is a concept that intersects with critical thinking. It does not tell the whole story.



Criticism is about finding fault with something. Critical thinking is about judgement, which can include finding faults and flaws, but has more emphasis on questioning and analysis.
Criticism is often directed at a person. Critical thinking should always be directed towards the argument (or produced work, or concept).
Criticism is sometimes driven by emotion. Critical thinking analyses emotion as part of the overall process.

討論的一直都是距離，所以我才說距離。torque = force x lever arm length

至於力量方面，橫拍的食指是橫放，發力能比得上直拍的直放的中指與無名指嗎？

1967年獲得世界冠軍的長谷川信彥為了解決橫拍正手力量不 ...

呢下真係有研究，球速係力量o既一道指標，同揮拍速度呈正比關係，結果顯示橫板平均揮速要比直板的高
