判斷以下那些是保守力,可能很難,但請給我最簡單的解釋就可以了

其實我想確定以下這些都不是保守力嗎?
1.離心力
2.強力(強交互作用)
3.弱力(弱交互作用)
4.向心力
5.正向力
6.科里奧利力(科氏力)
7.慣性力
8.張力

強力、弱力,可能目前科學還沒完全了解,只是我想知道目前是把它們看作非保守力嗎?

There are only four fundamental forces in nature. They are (i) gravitational force (引力), (ii) electromagentic force (電磁力), (iii) strong nuclear interaction force (強作用力), and (iv) weak nuclear interaction force (弱作用力).

"Conservative force" (保守力) is a term used in classical physics. Hence, the last two forces (i.e. strong and weak nuclear interaction forces) cannot be described using such term.

On your list, most of them are NOT real force. These "forces" arise because of inertia (慣性). The only force in the list that can be regarded as conservative is "tension", which is electromagentic in nature. Example is tension produced in stretching a spring.

離心力與科里奧利力是幻象,產生這些力純粹是因為其他物件旋轉時自己卻不會自行產生跟隨所需的力
