Chapter 1
Quantities and Measurement
Use units, estimates and uncertainty to judge measurements, and represent vector magnitude and direction consistently.
Chapter 2
Forces and Moments
Identify forces, use spring data, calculate turning effects and combine force and moment balances.
Chapter 3
Motion and Forces
Describe signed motion, interpret graphs, derive constant-acceleration equations and connect resultant force with momentum change.
Chapter 4
Energy and Fields
Account for energy, calculate work and power, and connect field direction with force and potential-energy changes.
Chapter 5
Projectile Motion
Use perpendicular motion components, calculate gravitational energy changes and explain a fall with air resistance.
Chapter 6
Collisions
Use signed impulse and momentum accounts, then distinguish elastic, separating inelastic and sticking collisions.
Chapter 7
Circular Motion
Describe uniform turns, identify the forces producing inward acceleration and apply gravity to circular satellite orbits.
Chapter 8
Currents
Connect charge flow and drift to source energy, electrical power and a measured useful output.
Chapter 9
Circuits
Read circuit connections, explain resistance and source behaviour, and calculate network and sensor outputs.
Chapter 10
Electromagnetism
Connect electric and magnetic fields to conductor forces, a current-balance measurement and the motion of charged beams.
Chapter 11
Nuclear Physics
Connect nuclear evidence and radiation measurements to decay, conservation, mass defect and energy release.
