Rotational Mechanics

Not started

Start with torque as the turning effect of force, use centre of mass and support region for static balance, then carry the same rotational language into moment of inertia, rolling motion, and angular momentum.

About recap mode

Keep the authored order, then open the extra explanation only when you need to understand how recap is choosing the next review move.

How it works

Same authored sequence, lighter revisit.

Recap mode does not invent a second curriculum. It keeps the existing starter-track order, then changes the prompt and suggested action with the current mastery and progress signals.

Keep using concept pages

Quick tests, challenge mode, worked examples, and read-next stay where they already live.

Recap links only jump you to the most useful surface for a fast review. The simulation-first concept pages still carry the real teaching work and keep the guided path intact.

Recap steps

Revisit the track in the same authored order.

Focus badges and button targets come from the current mastery and progress signals. The next ready checkpoint still stays in the loop.

    Torque

    Torque is still the next guided step in this authored order. No finished quick test, solved challenge, or completion mark is saved yet.

    Start here before moving into Static Equilibrium / Centre of Mass.
