Physics is less about memorising equations than knowing which one applies and why. The Study Mill turns your own physics lectures and problem sets into concept explanations, worked examples and quizzes — building the intuition that lets you tackle problems you have never seen before.
Physics exams are designed so that a formula sheet does not save you. The questions are unfamiliar by construction; what transfers is knowing which principle applies.
Part (a) sets up the system, and each later part builds on it. Getting (a) wrong can cost the whole question, so the setup deserves more time than it usually gets.
No numbers — "what happens to the period if you double the mass?". These reward understanding proportionality rather than plugging into a formula.
Start from a stated principle and reach a result. Marks are for the logical chain, so stating assumptions explicitly is worth doing.
The Study Mill generates questions in these formats from your own material — so practice looks like the exam, not like a glossary.
Two examples of what comes back after you upload a set of physics slides. Generated from your material, phrased the way your course tests it.
A block slides down a frictionless incline. Which forces do work on it, and which do not?
Gravity does positive work — it has a component along the displacement. The normal force does zero work: it acts perpendicular to the surface, and therefore perpendicular to the motion, and W = F·d·cosθ is zero when θ = 90°.
A ball is thrown straight up at 20 m/s. How long until it reaches its highest point? (g = 9.8 m/s²)
≈2.0 s. At the peak the velocity is momentarily zero, so from v = u + at: 0 = 20 − 9.8t, giving t = 20/9.8 = 2.04 s. Note the peak is defined by v = 0, not by acceleration being zero — gravity acts throughout.

Physics punishes formula-hunting: if you do not understand the concept, every new problem looks unfamiliar.
Know what each formula means physically and you will know when to reach for it.
A free-body or ray diagram turns a wall of text into a solvable problem.
Sanity-check answers by units and extreme cases — it catches most exam slips.
"Milli rebuilt my mechanics lectures as worked examples I could actually follow. Physics stopped feeling like guessing."
That is the main thing it is for in physics. Learn cards give you the physical meaning behind each relationship — what is actually conserved, what the proportionality implies — and you can keep asking follow-up questions until it makes sense. Knowing why is what lets you pick the right equation for a problem you have not seen.
Yes. Upload the sheet and you get variations at the same difficulty rather than the same questions returned, which is what you need once you already have the model answers.
Yes, though the useful split is that it is strongest on the conceptual scaffolding — what the field means, why the boundary condition is what it is — and you should still grind the vector calculus by hand. Most students find the concepts are the bottleneck and the algebra is just practice.
Walk & Learn is built for exactly that: two hosts teach one of your uploaded topics back to you as an audio session and ask questions you answer out loud. It suits conceptual physics well — proportional reasoning, definitions, why-questions — and suits problem-solving practice poorly, since you cannot draw a free-body diagram while walking.
