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
Dynamics
Identify the forces on an object and use their resultant to explain or calculate changes in motion.
04
Turning effects of forces
Calculate turning effects, balance moments and locate the centre of gravity of an object.
05
Pressure
Calculate pressure and density, explain hydraulic systems and interpret liquid-column pressure measurements.
06
Energy
Explain energy stores and transfers, calculate work and power, and use conservation of energy.
07
Kinetic particle model of matter
Explain the properties of solids, liquids and gases using particle arrangement, motion and interactions.
08
Thermal processes
Explain conduction, convection and radiation, and apply them to everyday designs.
09
Thermal properties of matter
Explain internal energy, calculate temperature and state changes, and interpret cooling data.
10
General properties of waves
Explain wave motion, interpret wave graphs, calculate wave speed and use sound echoes.
11
Electromagnetic spectrum
Compare electromagnetic waves by wavelength and frequency, explain their uses and distinguish exposure effects.
12
Light
Trace reflected and refracted rays, explain lens images and interpret optical measurements.
13
Static electricity
Explain charging, read electric fields and apply charge-and-force reasoning to experiments and particle collection.
14
Current of electricity
Connect charge, current, electrical energy and resistance, and interpret circuit measurements.
15
D.C. circuits
Read connections, apply series and parallel rules, and calculate currents and voltages in a complete circuit.
16
Practical electricity
Calculate appliance power, energy and cost, and explain mains connections and protective devices.
17
Magnetism
Explain magnet properties and induced magnetism, use a compass, and draw the required magnetic field patterns.
18
Electromagnetism
Predict current-produced fields, explain magnetic forces, and trace how an electromagnet or d.c. motor works.
19
Electromagnetic induction
Explain induced voltage, a.c. generation, transformer operation and reduced cable heating at high voltage.
20
Radioactivity
Interpret nuclei and radioactive emissions, correct detector readings and use half-life to explain applications and hazards.
