AP Physics 1 Flashcards: How to Learn 169 Cards for the New 8-Unit Course
Learn AP Physics 1 with 169 flashcards: kinematics, forces, energy, momentum, rotation, oscillations and fluids, with a reordered plan for the 2024-25 course.
Deck CM2580 "AP Chemistry" packs 176 cards that walk through the course in order: atomic structure, bonding and VSEPR, gases, solutions, reactions, kinetics, thermochemistry, equilibrium, acids and bases, and electrochemistry. Its definitions are clean. Its gap is that almost none of the cards ask you to calculate, and the AP exam (60 multiple-choice questions plus 7 free-response questions) mostly rewards calculation.

Before you start: trim and re-sort
- Cards 52 and 55-59 (molality, colligative properties, Raoult's law, van't Hoff factor) are outside the current AP Chemistry Course and Exam Description. Suspend them unless your class teaches them.
- The tail (cards 166-176) is an appendix. Move the common ion effect, Kc vs Kp and amphoterism into your equilibrium and acid-base reviews, and move mass spectrometry and empirical formulas to Unit 1.
- Card 105 defines entropy as "disorder". The College Board frames it as energy and matter dispersal, so rewrite the back in those terms; FRQ graders expect that wording.
- Card 133 lists H₂SO₄ as a strong acid. Add "first proton only"; HSO₄⁻ is weak (Ka ≈ 1.2 × 10⁻²).
- Missing exam topics: photoelectron spectroscopy, formal charge, hybridization, Beer-Lambert law, reaction mechanisms with a rate-determining step, and integrated rate laws (ln[A] vs t, 1/[A] vs t). Write 2-3 cards for each.
Tip: turn formulas into problems
For every equation card (37, 48, 92, 104, 108, 142, 159, 160), write one twin card that is a numbered problem. For example: "0.10 M acetic acid, 0.15 M acetate, pKa 4.74 → pH?" (answer: 4.92). Twenty such cards cover more of the free-response section than the other 150 cards together. Also add a card on which graph is linear for which order; that comes up every year in the kinetics questions.
