Questioning a Physics Problem: Taking Different Reference Frames

Click For Summary
The discussion revolves around resolving a physics problem involving potential energy by using different reference frames. The original poster initially calculated potential energy correctly but encountered discrepancies when changing the reference points for gravitational and elastic potential energy. They questioned whether dimensional analysis could serve as a reliable method for verifying the correctness of their solutions and minimizing errors. Participants emphasized the importance of consistent reference points for potential energy and suggested that dimensional analysis is a valuable tool for troubleshooting calculations. The conversation highlights the need for clear diagrams and organized problem-solving approaches to enhance understanding and accuracy in physics.

I think per Homework Forum Rules you have to try it before we help. I think the reason for this is that outlining an approach for you, is depriving you of developing that important part of the problems solution.
What would you consider the important part of the problems solution? Figuring it out on your own I or?
But no not at all, I will show you the solution, I've got it here :) I totally understand it and stuff.
But What I want to do is to improve the way of how I structure the problems. Because I tended to rush things through and also sometimes mid-problem got stuck simply because of not being able to recognize my past writing from what is for what aka (problems statics and strength of materials combined for example)

You see because I've never had science (or ... barely any) only biology actually 2h/week I am not very accustomed to following a structure that's clear and easily retracable for mistakes f.e.. If I showed to problems from the past you would NOT comprehend a single part if I am being honest.
Of course the books outlines an 'approach' but it's different you know.
And thus.. that is what I want to improve upon

I don't know, while it's tied to conservation of energy it is a completely different problem. It probably deserves its own thread. I'd suggest starting a new one.

(1) Practicing making/presenting good diagrams and supporting math in LaTeX is good practice, and practice makes perfect. If you need practice in exercising patience and effectively communicating scientific ideas, then that is the way to do it.

(2) It's not until you try to organize the problem and explain it to others (maybe many times over) that more efficient approaches become clear.

(1) and (2) are both important parts of the problem-solving process.

If you want to improve you must practice.

Thanks a lot for the advice! Will definitely do that from now, and for now I can only say those diagrams oh man.. to describe energy situations it really helps you visualize it instead of just thinking about it in your head.

anyways thank you
