Explain why nuclear fusion is not yet used for commercial electricity generation. (3 marks) → Answer: Requires extremely high temperatures/pressures; no net energy gain sustained; containment issues. 8. Conclusion The Edexcel GCSE Physics 2PH01 was a well-structured, rigorous linear qualification that provided strong preparation for A-level Physics. Its four-unit format allowed clear topic separation, and the lack of coursework reduced administrative burden while demanding strong exam technique. For educators and students revisiting this specification, its past papers remain a valuable question bank, but always cross-reference with the current 1PH0 specification for updated content and grading.

If you need a side-by-side topic comparison table or help converting 2PH01 past paper scores to 9-1 grade equivalents, let me know.
