Each chapter keeps explanations, definitions and exam advice together—without mixing in quizzes or practice questions.
CHAPTER 1
Motion, forces and energy
Use graphs and equations for motion, forces, momentum, work, power and energy transfers.
Resultant force causes acceleration, not constant speed.
CHAPTER 2
Thermal physics
Explain particle motion, temperature, thermal expansion and energy transfer.
Temperature measures average kinetic energy; heat is energy transferred.
CHAPTER 3
Waves
Apply wave speed and describe reflection, refraction, diffraction, sound and the electromagnetic spectrum.
Wave speed = frequency × wavelength.
CHAPTER 4
Light
Construct ray diagrams for mirrors and lenses and explain refractive effects.
Measure angles from the normal, not from the surface.
CHAPTER 5
Electricity
Calculate charge, current, potential difference, resistance, power and energy in circuits.
Current is the same at every point in a series circuit.
CHAPTER 6
Magnetism
Describe fields, electromagnets, motors, generators and transformers.
A changing magnetic field can induce an electromotive force.
CHAPTER 7
Nuclear physics
Compare types of radiation, half-life, fission, fusion and safety precautions.
Half-life is random for one nucleus but predictable for a large sample.
CHAPTER 8
Space physics
Explain the Solar System, stars, galaxies, redshift and the expanding Universe.
Greater redshift indicates a greater recession speed.
