Revision
Revision checklist
Can you explain each of these out loud, without looking? If not, re-read that lesson.
- Circular Motion: Deriving a = v²/r and applying F = mv²/r to orbits and roundabouts.
- Simple Harmonic Motion: Modelling oscillations with a = −ω²x and the mass–spring period.
- Momentum and Impulse: Using p = mv and impulse FΔt = Δp for impacts and safety design.
- Elastic and Inelastic Collisions: Applying conservation of momentum to elastic and inelastic collisions.
- Read each lesson's summary and re-do its practice questions from memory.
