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
Turning effects of forces
Calculate turning effects, balance moments and locate the centre of gravity of an object.
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
General properties of waves
Explain wave motion, interpret wave graphs, calculate wave speed and use sound echoes.
10
Electromagnetic spectrum
Compare electromagnetic waves by wavelength and frequency, explain their uses and distinguish exposure effects.
11
Light
Trace reflected and refracted rays, explain lens images and interpret optical measurements.
12
Electric charge and current of electricity
Connect charge, current, electrical energy and resistance, and interpret circuit measurements.
13
D.C. circuits
Read connections, apply series and parallel rules, and calculate currents and voltages in a complete circuit.
14
Practical electricity
Calculate appliance power, energy and cost, and explain mains connections and protective devices.
15
Magnetism and electromagnetism
Explain magnets and their fields, then connect electric current to magnetic fields, forces and coil rotation.
16
Radioactivity
Interpret nuclei and radioactive emissions, correct detector readings and use half-life to explain applications and hazards.
