📈 AP Microeconomics

10 starter terms · Basic Economic Concepts

Scarcity
The fundamental economic problem: unlimited wants but limited resources, forcing choices and trade-offs
Opportunity Cost
The value of the next-best alternative given up when a choice is made
Law of Demand
As price rises, quantity demanded falls (inverse relationship), ceteris paribus
Law of Supply
As price rises, quantity supplied rises (direct relationship), ceteris paribus
Equilibrium Price
The price where quantity demanded equals quantity supplied — the market clears
Price Elasticity of Demand
Measures how responsive quantity demanded is to a price change: %ΔQd ÷ %ΔP
Consumer Surplus
Difference between what buyers are willing to pay and what they actually pay
Marginal Cost
The additional cost of producing one more unit of output
Perfect Competition
Market with many firms, identical products, no barriers to entry; firms are price takers

Voice Leading
Smooth connection of chords: avoid parallel fifths/octaves, resolve tendency tones (7̂→1̂, 4̂→3̂)
Non-Chord Tones
Notes outside the harmony: passing tone, neighbor tone, suspension, appoggiatura, anticipation
Secondary Dominant

📉 AP Precalculus

Exponential Function
f(x) = a·bˣ — constant PERCENT change per unit; b>1 growth, 0<b<1 decay
Logarithm
The inverse of exponentiation: log_b(x) = y means bʸ = x
Radian

Unit Circle Values
cos θ = x-coordinate, sin θ = y-coordinate of the point at angle θ on the circle of radius 1
Sinusoidal Function

⚡ AP Physics C: E&M

10 starter terms · Electrostatics: Charge, Field, and Potential

Coulomb's Law
F = kq₁q₂/r² — electrostatic force between point charges, along the line joining them
Electric Field
Force per unit charge: E = F/q. Points away from positive charges, toward negative
Gauss's Law
Flux through a closed surface equals enclosed charge over ε₀: ∮E·dA = Q/ε₀
Electric Potential

Capacitance
C = Q/V. Parallel plate: C = ε₀A/d. Stores energy U = ½CV²
Ohm's Law & Resistivity
V = IR; resistance R = ρL/A depends on material and geometry
Kirchhoff's Rules
Junction: currents in = currents out (charge conservation). Loop: ΣΔV = 0 (energy conservation)
Magnetic Force
F = qv × B on charges, F = IL × B on wires — always perpendicular to velocity
Ampère's Law
∮B·dl = μ₀I_enc — relates magnetic field circulation to enclosed current
Faraday's Law
EMF = −dΦ/dt: changing magnetic flux induces EMF; Lenz's law gives the minus sign

🔬 AP Research

10 starter terms · Research Questions and Inquiry Design

The Academic Paper
4,000–5,000 word original research paper — 75% of the AP score; presentation + defense is 25%
Gap in the Literature

Research Question
Focused, researchable, feasible in one year: narrow scope beats grand ambition
Literature Review
Synthesizes existing scholarship by THEME (not source-by-source summary) to reveal the gap
Methodology
Your systematic approach: qualitative, quantitative, or mixed methods — must align with the question
IRB
Institutional Review Board approval required before any research involving human subjects
Validity vs. Reliability
Validity: measures what it claims. Reliability: produces consistent results on repetition
Sampling Methods
Random, stratified, convenience, snowball — each carries different bias risks you must acknowledge
Limitations

🎨 AP 2-D Art & Design

10 starter terms · Elements and Principles in 2-D Design

Portfolio Structure
Sustained Investigation (15 images + writing, 60%) and Selected Works (5 finished pieces, 40%) — no timed exam
Sustained Investigation
A year-long inquiry guided by your own question, showing practice, experimentation, and revision
Elements of Art
Line, shape, color, value, texture, space, form — the raw vocabulary of every composition
Principles of Design
Balance, contrast, emphasis, movement, pattern, rhythm, unity, variety, proportion
Inquiry Question
Drives the portfolio: specific and visual ('How can distortion express anxiety?') beats vague themes
Documentation of Process
Sketches, failed attempts, and revisions ARE scoring evidence — photograph everything
Color Theory
Complementary contrast, analogous harmony, temperature, saturation — deliberate palettes score higher
Composition Strategies
Rule of thirds, leading lines, framing, figure-ground relationships, cropping for tension
Writing Component
1,200 characters on your inquiry + 100 per image on materials, processes, and ideas
Artistic Integrity
Work from your own photos/observation; cited appropriation only — plagiarized imagery voids the portfolio

🗿 AP 3-D Art & Design

10 starter terms · Form, Space, and 3-D Design Principles

Portfolio Structure
Sustained Investigation (15 images showing works in the round) + Selected Works (5 pieces, 2 views each)
Form vs. Shape
Shape is 2-D; form occupies real space with height, width, AND depth — the heart of 3-D design
Additive vs. Subtractive
Additive: building up (clay, welding, assemblage). Subtractive: carving away (wood, stone, foam)
Positive & Negative Space
The mass of the object AND the voids around/through it — Henry Moore made holes eloquent
Armature
Internal skeleton (wire, wood) supporting clay or plaster during construction
Scale & Proportion
Size relative to the human body changes meaning — Oldenburg's giant everyday objects
Texture & Surface
Actual (touchable) vs. implied; patina, glaze, and finish decisions are scoring evidence
Balance in 3-D
Physical AND visual: symmetrical, asymmetrical, cantilevered — gravity is part of the medium
Installation & Site
Work that responds to its space; document multiple angles and viewer relationship
Craftsmanship
Joints, seams, and finishing show intentionality — sloppy construction reads as unresolved ideas

Linear Perspective
1-point, 2-point, 3-point systems for constructing believable space
Atmospheric Perspective
Distant objects: lighter value, less contrast, cooler color, softer edges
Foreshortening
Compressing forms that project toward the viewer — the hardest observational skill
Composition & Cropping
Where the figure meets the frame creates tension; avoid centering everything
Observational vs. Imaginative
Colleges want to see BOTH: rigorous observation and inventive personal imagery
