Mastery checklist

Know what success looks like.

  1. 01

    Define the system, then show every external interaction with a clear direction.

  2. 02

    Apply Newton's laws or a conservation law component by component.

  3. 03

    Test the result against units, limiting cases, and the direction of the predicted change.

Exam lens

Build, apply, check.

A.4 Rigid body mechanics is identified as HL only in this curriculum map. Build the concept first, then practise selecting a model, showing working, and checking the final result.
