I am looking for some kind of a diagram, general or analytic, that shows all the different kind of Physics "Departments"-"Studies" or what you would call them, like Quantum Physics, Physics of Sound Waves, or something like that.
I know it is a very general question but anything you know of...
Aaaaa, I think i get it, so I will say:
Spring 1 extends by x1
Spring 2 x2
All in all x
So x1 + x2 = x
-F/D1 - F/D2 = -F/D
And then divide everything with -F ?
Or is this false?
