Questioning a Physics Problem: Taking Different Reference Frames

Click For Summary
SUMMARY

The forum discussion centers on the application of dimensional analysis and the selection of reference frames in solving physics problems involving potential energy. Users debate the correct choice of zero potential energy levels for gravitational and elastic potential energy, emphasizing the importance of consistency in reference frames. Dimensional analysis is confirmed as a crucial tool for verifying the correctness of derived equations, allowing users to identify errors in their calculations. The conversation highlights the necessity of clear diagrams and organized problem-solving approaches to enhance understanding and minimize mistakes.

PREREQUISITES
  • Understanding of potential energy concepts, specifically gravitational and elastic potential energy.
  • Familiarity with dimensional analysis as a method for verifying equations.
  • Basic knowledge of calculus, particularly integration for deriving potential energy functions.
  • Proficiency in using LaTeX for mathematical expressions and diagrams.
NEXT STEPS
  • Study the principles of gravitational potential energy and elastic potential energy in detail.
  • Learn how to apply dimensional analysis in various physics problems to check for consistency.
  • Explore the derivation of potential energy functions using calculus, focusing on integration techniques.
  • Practice creating clear and informative diagrams to support mathematical solutions in physics.
USEFUL FOR

Students of physics, educators teaching mechanics, and anyone interested in improving their problem-solving skills in physics through dimensional analysis and effective diagramming techniques.

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
