28 interactive flashcards covering linear momentum, impulse, the impulse-momentum theorem, conservation of momentum, and elastic vs. inelastic collisions. Tap a card to flip it.
Active recall is the most effective way to study. Look at the question, try to answer out loud before tapping to flip. If you got it wrong, mentally note it and come back to it.
Unit 4 is short on equations but heavy on conceptual distinctions: momentum vs. KE, elastic vs. inelastic, internal vs. external forces. Master those and the calculations are easy.
