Why Most Physics Templates Are a Waste of Time
I spent three semesters debugging LaTeX documents for undergraduate physics problem sets before I stopped trying to make everything look pretty and started building something that actually worked. The result was a stripped-down template system I called Physics Template Minimalist, and it cut my document preparation time from about two hours down to roughly fifteen minutes per problem set. Most people never get there because they get stuck on styling instead of structure. The whole thing lives in a single .tex file with about eighty lines of preamble and a clean body structure. You start by setting up the document class. I use article with a4paper and 11pt. Anything larger and your equations get pushed off-center. Anything smaller and the margin notes become unreadable when you have multi-line derivations. The preamble packages are where most templates bloat. You only need a handful. amsmath and amssymb for the equations. amsthm if you want proof environments. physics for things like \qty and \vec shortcuts. inputenc with utf8 support. fontenc with T1. That is it. Everything else is decoration that slows down compilation and adds no value to grading.
I define custom commands early on. \newcommand{\F}{\mathbf{F}} for force vectors, \newcommand{\nhat}{\mathbf{\hat{n}}} for normal vectors, \newcommand{\lap}{\nabla^2} for Laplacians. Having these baked in means you are not typing out lengthy notation every time you set up a problem. It seems minor until you have written the same vector expression forty times in one document and your fingers start making mistakes. The body structure has three parts: problem statement, setup, and solution. I keep them visually separated with thin horizontal rules. Problem statement gets the given quantities listed out explicitly. Setup is where you write the governing equations before substituting numbers. Solution is the algebra and arithmetic. People skip setup and jump straight to plugging values into formulas they pulled from memory, which is exactly how sign errors creep into your answers.
How It Actually Feels in Practice
There is a specific edge case that almost broke this system for me during my second year. I was working through a problem involving rotating reference frames with a Coriolis term where the velocity vector needed to be expressed in polar coordinates but the problem gave me Cartesian components. The template had a hardcoded coordinate system assumption baked into one of my custom \define commands, and it silently produced wrong signs on the cross product terms. I spent three hours convincing myself the physics was wrong before I realized the template was transforming the vector incorrectly. The workaround was simple but embarrassing in hindsight. I removed the hardcoded coordinate transform from the custom command and instead defined a pure conversion function using the physics package's built-in capabilities. The corrected approach used explicit basis vector declarations at the top of each problem rather than assuming a single convention throughout the document. This meant every problem could declare its own coordinate system independently. It added about twenty extra lines to the preamble but eliminated that entire class of error. What most people do not realize about template-driven physics work is that the template itself becomes part of your reasoning process. The act of filling in structured fields forces you to separate what you know from what you need to find. When you have a blank template with clearly labeled sections, you cannot hide from the fact that you do not actually know which equation applies. I have seen students produce elegant fifty-page documents that contained zero correct physics because the template gave them the illusion of progress while they were still figure out the problem.

Another counter-intuitive thing: less equation formatting is better. Default LaTeX equation spacing is actually quite good for physics. Trying to manually adjust \interdisplaylinepenalty or tweaking \arraystretch usually makes things worse. The only real formatting decisions that matter are whether you use \begin{align} versus \begin{multline} and when to break long derivations across multiple blocks. Keep alignment points intentional, not decorative. One ampersand per line for the equal signs you actually care about showing, nothing more. The download itself is just a zip containing the main .tex file, a sample problem set with seven worked examples covering mechanics and electromagnetism, and a one-page reference sheet for the custom commands. The sample problems are written so you can see exactly how the structure maps to actual physics work. I would recommend copying the sample files and modifying them rather than starting from a blank template. Reading through someone else's correct setup is faster than debugging your own incorrect one.
Where This Approach Breaks Down
Physics Template Minimalist does not handle everything. If you are doing computational physics or generating plots with pgfplots, the template adds almost no value and you are better off with a full document class tailored to scientific figures. If your problem sets involve heavy matrix notation or tensor calculus, you will find yourself constantly extending the preamble and the benefit over a plain editor disappears after about four pages of content. The rigid three-section structure also assumes you are solving standard textbook problems. Research-style derivations where the setup and solution are intertwined do not fit cleanly into this format. I have tried forcing that structure and it produces documents that look organized but read poorly. In those cases, a simple section-based approach with numbered equations is more honest about what you are doing. If you are doing graduate-level work with heavy citation requirements, you will want to integrate a bibliography manager from the start rather than grafting one on later. The minimal template approach works best for course problem sets and exam preparation where the primary output is handwritten-style derivations rendered cleanly on the page. That is where it saves time. Outside of that, the overhead of maintaining a custom template outweighs the benefits.
I use it still. About once a week when I am helping students with homework or drafting solutions for tutoring sessions. The time savings are real but modest once you have the template memorized. The larger benefit is consistency. Every document looks the same, every equation is formatted the same way, and there is no decision-making friction when you should be working on the physics instead. That friction reduction is worth the initial investment even if the raw time savings are smaller than people claim.
