Special Relativity
A reviewed 9814 repair guide for Special Relativity.
Before you begin
Use the diagnostic result to follow the H3 explanation, worked transfer, guided practice and independent practice before assessment and delayed re-test. H2 is tracked separately.
How the ideas connect
- Michelson–Morley result and relativity postulates
- Simultaneity, Lorentz transformations, time and length
- Relativistic velocity and energy–momentum

Objective clusters
- 01Michelson–Morley result and relativity postulatesThe null result undermines the stationary ether model; state invariant physical laws and light speed and explain why Galilean transformation fails for light.
- 02Simultaneity, Lorentz transformations, time and lengthIdentify events, frame and proper quantity first; apply Lorentz transformations and derive or use the Lorentz factor with a consistent sign convention.
- 03Relativistic velocity and energy–momentumUse relativistic velocity addition and E² = (pc)² + (mc²)², then verify the massless and low-speed limiting cases.

Course coverage and review details
This standalone 9814 loop covers 9814 additional topic 5(a)–(j), PDF page 13. H2 Physics 9478 has its own separate course, examination and mastery record; optional H3 archive extensions are excluded.
Recorded selected-response work supports formative repair. It does not by itself prove constructed, diagrammatic or practical performance.
