Motion
- Motion: Distance, Speed & VelocityScalars and vectors, distance versus displacement, speed versus velocity, and average speed problems.
- Acceleration & Free FallAcceleration as change in velocity over time, the motion equations, and free fall at g = 9.8 m/s², incl. objects thrown straight up or dropped (owns vertical-only motion).
- Projectile MotionObjects launched horizontally or at an angle: horizontal and vertical motion handled separately, time of flight, range and the path (straight up/down: Acceleration).
- Rotation & Uniform Circular MotionAngular quantities, torque, centripetal acceleration and force, and why an object moving in a circle is accelerating (satellites and orbits: Gravitation).
Forces
- Newton's Laws of MotionInertia, F = ma, action-reaction pairs, free-body diagrams, and net force.
- FrictionStatic versus kinetic friction, the coefficient of friction, and how friction opposes motion (the normal force itself: Newton's Laws).
- Universal Gravitation, Mass & WeightNewton's law of universal gravitation, the inverse-square rule, mass versus weight, and orbits in brief.
- Density, Pressure & BuoyancyDensity as mass per volume, pressure as force per area, fluid pressure with depth, and Archimedes' principle — why things float.
Energy & momentum
Waves, sound & light
- Waves & SoundTransverse and longitudinal waves, wavelength, frequency, amplitude and speed (owns the wave equation, light waves too), sound and pitch, and the Doppler effect.
- Light & the Electromagnetic SpectrumThe electromagnetic spectrum, the speed of light, the law of reflection, and refraction (index of refraction, Snell's law in brief).
- Optics: Mirrors & LensesImage formation only: plane, concave and convex mirrors, converging and diverging lenses, focal point, and real versus virtual images.
Electricity & magnetism
- Electric Charge, Static Electricity & FieldsPositive and negative charge, charging by friction and induction, Coulomb's law, conductors versus insulators, and electric fields.
- Current, Voltage, Resistance & Ohm's LawCurrent, voltage and resistance, Ohm's law, series versus parallel circuits, and electric power.
- Magnetism & ElectromagnetismMagnetic poles and fields, how a current makes a magnetic field, electromagnets, and electromagnetic induction.
