Physics · Units 1–16
Unit 37 · 3 outcomes
Vectors and Equilibrium
A vector has size and direction. 5 m east is a vector. 5 m by itself is a scalar. Unit 1 on the PMDC list is only three skills: add vectors with perpendicular parts, the dot product, and the cross product.
1.1 · 1.2 · 1.3
Unit 38 · 17 outcomes
Force and Motion
Unit 2 is how things move, and why. First the words (displacement, velocity, acceleration), then graphs, then a ball in the air, then Newton’s three laws and collisions.

Unit 39 · 8 outcomes
Work and Energy
Work is a force moving its point of application. Energy is the ability to do that work. Unit 3 is work, kinetic energy, potential energy, power, friction-heat, and efficiency.

Unit 40 · 4 outcomes
Rotational and Circular Motion
Unit 4 on the PMDC list is the dictionary of turning: angle in radians, angular velocity, and how those link to ordinary linear s, v and a. Stay inside 4.1–4.4.

Unit 41 · 10 outcomes
Fluid Dynamics
Unit 5 is fluids that move: a falling raindrop that stops speeding up, drag, laminar vs turbulent flow, Av = constant, and Bernoulli — including why a narrow artery raises speed and drops pressure.

Unit 42 · 18 outcomes
Waves
Unit 6 is long: what a wave is, v = f λ, sound, superposition, standing waves on strings and in pipes, then SHM and the shadow of circular motion. One idea at a time.

Unit 43 · 7 outcomes
Thermodynamics
Unit 7 is heat flow, work by expanding gases, the first law, and why C_p is bigger than C_v by R. Signs: on this site W is work done on the system unless a stem says ‘by’.

Electrostatics
Unit 8 is still charges: Coulomb, the field as a force-per-charge, field lines, an infinite sheet, potential, and a capacitor charging through a resistor.

Unit 45 · 5 outcomes
Current Electricity
Unit 9 is a steady flow of charge, Ohm’s law, how resistivity cares about temperature, the hidden r inside a battery, and when a load takes maximum power.
9.1 · 9.2 · 9.3 · 9.4 · 9.5
Unit 46 · 4 outcomes
Electromagnetism
Unit 10 is the magnetic field as a flux density, flux as B · A, and what a charged particle does when it flies across B — a circle, with F always sideways.
10.1 · 10.2 · 10.3 · 10.4
Unit 47 · 4 outcomes
Electromagnetic Induction
Unit 11 is a changing flux making an emf, Lenz’s fight, and transformers — why we send power as high-voltage AC.
11.1 · 11.2 · 11.3 · 11.4
Unit 48 · 3 outcomes
Alternating Current
Unit 12 is the phase of AC, what R, C and L each do to that phase, and the EM spectrum from radio to gamma.
12.1 · 12.2 · 12.3
Unit 49 · 2 outcomes
Electronics
Unit 13 on the PMDC list is two outcomes only: rectification with diodes, and the PN junction with forward and reverse bias. No transistors, no gates.
13.1 · 13.2
Unit 50 · 1 outcome
Dawn of Modern Physics
Unit 14 is one outcome: light as particles (photons) with energy E = h f. Intensity is how many packets. Colour is how big each packet is.

Unit 51 · 1 outcome
Atomic Spectra
Unit 15 is line spectra: why atoms print sharp colours, emission vs absorption, and the hydrogen series (Lyman, Balmer, Paschen).

Nuclear Physics
Unit 16 is a simple atom, decay that no one can timetable, half-life, and what radiation does to tissue — plus why hospitals still use it.
