A path, not a pile of pages.

Ask is still for exploration. This sequence is the ground-up order: units before motion, forces before energy, circuits after charge. Each step is one question. Mastery is a check you can fail.

  1. 01 · explain

    Measurement, units, dimensions

    Mastery: Convert a stated quantity and catch a dimension error.

  2. 02 · explain

    Algebra, graphs, vectors, estimation

    Mastery: Add two displacements and estimate an order of magnitude.

  3. 03 · explain

    Motion

    Mastery: Read a v–t sketch and say what the object is doing.

  4. 04 · explain

    Forces and free-body diagrams

    Mastery: Name every force on a block on a rough incline.

  5. 05 · calculate

    Energy and momentum

    Mastery: Compute ½mv² from complete inputs; refuse it when v is missing.

  6. 06 · explain

    Rotation, statics, load paths

    Mastery: Torque as force times lever arm, not a magic strength.

  7. 07 · explain

    Fluids

    Mastery: Pressure, head, and NPSH as different statements.

  8. 08 · explain

    Heat and thermodynamics

    Mastery: Temperature vs heat vs conductivity.

  9. 09 · explain

    Charge, voltage, DC circuits

    Mastery: Current is a loop; voltage is a difference.

  10. 10 · explain

    Magnetism, induction, AC, three-phase

    Mastery: Faraday first; then three-phase as three displacements.

  11. 11 · explain

    Materials, controls, system response

    Mastery: Error, actuator, and the thing being measured.

  12. 12 · explain

    Plant integration and evidence

    Mastery: Separate observation, inference, and the project record.
