H3 Physics 9814 · Topic 2
Rotational Motion
A reviewed 9814 repair guide for Rotational Motion.
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
- Angular kinematics
- Angular momentum, inertia and torque
- Rotational energy and rolling

Lesson route
Objective clusters
- 01Angular kinematicsRigid-body points share angular displacement, velocity and acceleration, while tangential quantities depend on distance from the fixed axis.
- 02Angular momentum, inertia and torqueDefine the axis, account for mass distribution, and use torque as the rate of change of angular momentum; apply calculus or the parallel-axis theorem within scope.
- 03Rotational energy and rollingCombine centre-of-mass translation with rotation about the centre of mass, use ½Iω², and enforce the no-slip contact constraint before analysing friction.

Course coverage and review details
This standalone 9814 loop covers 9814 additional topic 2(a)–(g), PDF page 10. 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.
