Mastery checklist

Know what success looks like.

  1. 01

    Track energy transfers with a clearly stated system boundary.

  2. 02

    Choose the appropriate work, energy, or power relationship and keep its sign convention visible.

  3. 03

    Account for useful output, dissipation, and conservation before judging the final value.

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.
