Quantifies acceleration as the rate of velocity change and applies kinematic equations. Connects graphical slopes to physical acceleration values.

Lesson 3 • Friction, Gravity, and Normal Force

Analyses contact and gravitational forces acting on objects at rest and in motion. Extends Newton's laws to multi-force scenarios.

Lesson 4 • Newton's Three Laws of Motion

States and applies inertia, F = ma, and action-reaction principles to real scenarios. Provides the causal framework linking forces to motion changes.

Lesson 1 • Simple Machines and Mechanical Advantage

Analyses levers, pulleys, inclined planes, and other simple machines using work principles. Quantifies mechanical advantage and trade-offs between force and distance.

Lesson 2 • Kinetic and Potential Energy

Quantifies kinetic energy from mass and velocity, and potential energy from position or deformation. Builds the energy accounting system used in conservation problems.

Lesson 3 • Work and the Work-Energy Theorem

Defines work as force times displacement and derives the work-energy theorem. Distinguishes situations where force does and does not perform work.

Lesson 4 • Power and Efficiency

Defines power as the rate of work and efficiency as useful output divided by total input. Connects these concepts to machine and engine performance.

Lesson 1 • Heat Transfer: Conduction

Explains particle-to-particle energy transfer through direct contact in solids. Relates thermal conductivity to material structure and practical insulation.

Lesson 2 • Temperature and Thermal Energy

Distinguishes temperature as average kinetic energy from thermal energy as total internal energy. Introduces Celsius, Fahrenheit, and Kelvin scales with conversions.

Lesson 3 • Heat Transfer: Convection and Radiation

Describes fluid circulation in convection and electromagnetic energy transfer in radiation. Connects both mechanisms to weather, climate, and heating systems.

Lesson 4 • Phase Changes and Latent Heat

Explains energy absorbed or released during melting, freezing, vaporisation, and condensation. Applies latent heat calculations to heating and cooling curves.

Lesson 1 • Wave Properties and Types

Defines amplitude, wavelength, frequency, and wave speed for transverse and longitudinal waves. Establishes the universal wave equation v = fλ.

Lesson 2 • Wave Behaviours

Analyses reflection, refraction, diffraction, and interference as universal wave behaviours. Applies each behaviour to predict wave interactions with boundaries and obstacles.

Lesson 3 • Sound Waves and Acoustics

Characterises sound as a longitudinal pressure wave requiring a medium. Connects pitch, loudness, and timbre to frequency, amplitude, and waveform.

Lesson 4 • The Electromagnetic Spectrum

Orders electromagnetic waves from radio to gamma by frequency and energy. Identifies practical uses and hazards associated with each spectral region.

Lesson 1 • Resistance and Ohm's Law

Introduces resistance as opposition to current and applies Ohm's law V = IR. Relates resistivity to material properties and temperature.

Lesson 2 • Electric Charge and Electric Force

Introduces charge, conductors, insulators, and Coulomb's law for electrostatic force. Connects charge interactions to everyday static electricity phenomena.

Lesson 3 • Series and Parallel Circuits

Analyses current, voltage, and resistance in series and parallel configurations. Applies Kirchhoff's rules to solve multi-component circuit problems.

Lesson 4 • Electric Potential and Current

Defines voltage as electric potential difference and current as charge flow rate. Establishes the energy-per-charge framework underlying circuit analysis.
