Energy & Fields: stores, work, fields and power
Track energy transfers consistently, connect work to kinetic and potential-energy change, then apply power and efficiency.
Before you begin
Study each reviewed objective cluster, then use the recorded diagnostic and repair plan. H2 practice evidence remains separate from H1 and H3.

Course coverage and review details
The established 4(f)–(i) field-stage resource IDs and base fragment links are preserved while the surrounding Topic 4 groups are added.
Coverage is reviewed against 9478 topic 4(a)–(n), PDF page 14. Selected-response progress does not by itself prove constructed, diagrammatic or practical performance.
