Goal: AP Physics 2 course framework (College Board), AP

## 1. Thermodynamics

- [Reactions That Release or Absorb Heat](https://ai.page/c/reactions-that-release-or-absorb-heat/index.md): Distinguish between exothermic reactions (release energy, temperature rises) and endothermic reactions (absorb energy, temperature falls), with everyday and industrial examples
- [Conduction, convection, and radiation](https://ai.page/c/conduction-convection-and-radiation/index.md): Describe and compare the three mechanisms of heat transfer — conduction (particle vibration through solids), convection (fluid movement in liquids/gases), and radiation (infrared waves) — and explain that the rate of transfer depends on temperature difference

## 2. Electric Force, Field, and Potential

- [Universal Gravitation](https://ai.page/c/universal-gravitation/index.md): Describe gravity as a universal attractive force between all masses, explain that orbital motion arises because gravity provides the centripetal force keeping objects in orbit, and compare gravitational field strengths on different planets

## 3. Electric Circuits

- [Ohm's Law: voltage, current, resistance](https://ai.page/c/ohm-s-law-voltage-current-resistance/index.md): Apply Ohm's Law (V = IR) to calculate current, voltage, or resistance in a simple circuit, and explain that resistance opposes the flow of current
- [Power: watts and energy per second](https://ai.page/c/power-watts-and-energy-per-second/index.md): Define power as the rate of energy transfer (power = energy ÷ time, measured in watts), and compare energy transfer rates in different everyday contexts
- [Series vs parallel circuits](https://ai.page/c/series-vs-parallel-circuits/index.md): Describe and apply the rules for current, voltage, and resistance in series and parallel circuits, and explain the practical uses of each circuit type

## 4. Magnetism and Electromagnetism

- [Electromagnets](https://ai.page/c/electromagnets/index.md): Describe the magnetic effect of an electric current (a current-carrying wire produces a magnetic field), and investigate how the strength of an electromagnet depends on current, number of coil turns, and core material
- [Motors & the Motor Effect](https://ai.page/c/motors-and-the-motor-effect/index.md): Explain the motor effect as the force on a current-carrying conductor in a magnetic field, and describe how this principle is used in electric motors and loudspeakers

## 5. Geometric Optics

- [Ray Diagrams & Images](https://ai.page/c/ray-diagrams-and-images/index.md): Construct ray diagrams to show the formation of images by plane mirrors and converging lenses, identifying whether images are real or virtual, magnified or diminished, upright or inverted

## 6. Waves, Sound, and Physical Optics

- [The Electromagnetic Spectrum](https://ai.page/c/the-electromagnetic-spectrum/index.md): Describe the full electromagnetic spectrum from radio waves to gamma rays, in order of increasing frequency and energy; explain that all EM waves travel at the same speed in a vacuum; and describe the uses and hazards of different regions
- [Waves & Different Materials](https://ai.page/c/waves-and-different-materials/index.md): Explain how waves can be absorbed, transmitted, or reflected by different materials, and apply these interactions to explain colour perception, sight, communication technologies, and the effects of different surfaces on wave behaviour
