As I have said often before, each word/idea is a problem and a challenge in how to represent it graphically. “Force” I find a very difficult concept to illustrate. “Something that tends to influence the motion of a body” is a definition I have read. But that is very vague and incomplete! If and when I come up with an effective, accurate id for “force” I’ll really think I have something. And I will.
Now I didn’t provide notes for the above. If anyone would like them, write to me.
