Mastery checklist
Know what success looks like.
- 01
Track energy transfers with a clearly stated system boundary.
- 02
Choose the appropriate work, energy, or power relationship and keep its sign convention visible.
- 03
Account for useful output, dissipation, and conservation before judging the final value.
Exam lens
Build, apply, check.
5 Work, energy and power sits inside AS Level foundations. Build the concept first, then practise selecting a model, showing working, and checking the final result.
