Debugging Classical Mechanics, a free science course on Tomo

Debugging Classical Mechanics

Bridge the gap between memorizing formulas and setting up physics problems correctly. Uncover the subtle intuition traps around forces, friction, circular motion, and conservation laws that derail intermediate problem solvers.

Like Duolingo, but for Debugging Classical Mechanics. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

A short one: 11 levels across 2 sections, about 22 minutes end to end, roughly 4 days at five minutes a day. It moves through Fixing Free-Body Traps and Navigating Motion and Conservation Conditions. It assumes you already know the basics.

Key ideas in Debugging Classical Mechanics

  • Inertia keeps an object coasting at steady speed without any forward driving force.
  • Forces require an identifiable physical agent; no physical agent pushes a coasting puck forward.
  • Constant velocity implies acceleration is zero, so the vector sum of all forces must be zero.
  • Normal force is a passive contact force that adjusts to prevent surface penetration.
  • On an incline, the normal force only counters the perpendicular component of gravity.
  • Vertical acceleration or external pushing changes how hard surfaces must press together.
  • Newton's third law interaction pairs always act on two distinct, interacting objects.
  • The reaction to the table pushing up on the book is the book pushing down on the table.
  • The reaction to Earth's gravity on the book is the book's gravitational pull on Earth.
  • A taut ideal string can only pull along its length; it cannot push or exert thrust.
  • Tension exerts an inward-directed pulling force at both endpoints toward the string's center.
  • Tension magnitude is uniform along an ideal massless string passing around ideal pulleys.
  • Driven tires push backward against the road, so the road pushes forward
  • Friction opposes the relative slipping between surfaces, not vehicle motion
  • Static friction provides the net external forward force that accelerates the car
  • Static friction is an self-adjusting inequality up to a maximum threshold

Questions

Questions about Debugging Classical Mechanics

  1. How do I learn Debugging Classical Mechanics?

    Go in order: start with Fixing Free-Body Traps, then Navigating Motion and Conservation Conditions. On Tomo that's 11 short levels, about 22 minutes in all, played five minutes a day. Start free and play the first level in under a minute.

  2. Is there a Duolingo-style app for Debugging Classical Mechanics?

    Yes. Tomo works like Duolingo: short daily lessons, streaks and quick quizzes. Debugging Classical Mechanics is one of its free courses, and you can type any other topic to get a course of your own.

  3. Is the Debugging Classical Mechanics course free?

    Yes. Debugging Classical Mechanics is playable on Tomo's free plan, which doesn't expire. No credit card, no waitlist. Download the app and start your first lesson.

  4. How long does it take to learn Debugging Classical Mechanics?

    11 levels across 2 sections, about 22 minutes of play in total. It's built for five minutes a day, so you finish it a little at a time instead of all at once.

  5. Do I need any background to start Debugging Classical Mechanics?

    No. It's pitched at an intermediate level, so it starts where you are and builds up. If you can tap a phone, you can start.
