Lagrangian depend upon upon my choice of generalized coordinates?

AI Thread Summary
The Lagrangian does depend on the choice of generalized coordinates, as demonstrated with a particle mass m in one dimension under a potential V=V(x). When shifting coordinates from x to y=x+c, the potential changes to V(y-c), indicating that V(x) and V(y-c) are generally different. Despite this difference in the Lagrangian, the resulting equations of motion remain equivalent. Selecting appropriate coordinates can simplify the process of solving these equations. Thus, while the Lagrangian varies with coordinate choice, the physical outcomes remain consistent.

The Lagrangian does depend on your generalised coordinates.

Consider a particle mass m in one dimension, in a potential V=V(x).
Then
L=T-V= \frac{1}{2}m\dot{x}^{2} - V(x)

If instead of using x we used some shifted coordinate y=x+c, where c is some constant, then V=V(y-c)

L=T-V=\frac{1}{2}m\dot{y}^{2} - V(y-c)

Now notice that in general V(x) and V(y-c) are different (for example if V(x)=x).

However the equations of motion you derive from them will be equivalent. (Often choosing a clever set of coordinates makes the equations of motion easier to solve).
 
Thread 'Question about pressure of a liquid'
I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...
I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
