01
Physical quantities and measurement
Use units and prefixes, choose measuring instruments and methods, and distinguish scalars from vectors.
02
Kinematics
Learn about distance, speed, velocity, acceleration and free fall. Use motion graphs to describe movement and calculate distance and acceleration.
03
Force and pressure
Distinguish mass from weight, determine density from measurements and explain pressure at a surface.
04
Dynamics
Identify the forces on an object and use their resultant to explain or calculate changes in motion.
05
Energy
Explain energy stores and transfers, calculate work and power, and use conservation of energy.
06
Kinetic particle model of matter
Explain the properties of solids, liquids and gases using particle arrangement, motion and interactions.
07
Thermal processes
Explain conduction, convection and radiation, and apply them to everyday designs.
08
General properties of waves
Explain wave motion, interpret wave graphs and calculate wave speed.
09
Electromagnetic spectrum
Compare electromagnetic waves by wavelength and frequency, explain their uses and distinguish exposure effects.
10
Electric charge and current of electricity
Connect charge, current, electrical energy and resistance, and interpret circuit measurements.
11
D.C. circuits
Read connections, apply series and parallel rules, and calculate currents and voltages in a complete circuit.
12
Practical electricity
Calculate appliance power, energy and cost, and explain mains connections and protective devices.
13
Radioactivity
Interpret nuclei and radioactive emissions, correct detector readings and use half-life to explain applications and hazards.
