These 220 English flashcards cover all four official ASVAB domains and map to the ten computerized subtests without copying the test. #### What the cards practice * **Verbal — 45 cards:** produce meanings for 20 useful words, connect 10 roots or affixes with their meanings and examples, and recall 15 bounded reading concepts such as main idea, inference, tone, context clues, and passage structure. * **Math — 55 cards:** recall number rules, algebra relationships, geometry formulas, and ten common setup patterns for rates, interest, percent change, mixtures, work, probability, scale, and word-to-expression translation. * **Science — 40 cards:** connect life-science structures and processes, chemistry and physics terms, and Earth and space processes with their defining functions or principles. * **Technical — 65 cards:** connect electrical quantities, circuit behavior, vehicle and shop components, tools, simple machines, and physical principles with their functions, units, formulas, or relationships. * **Spatial — 15 cards:** recall bounded rotation, reflection, boundary-matching, silhouette, overlap, scale, landmark, symmetry, and viewpoint concepts that support spatial-relation practice. The cards use useful forward mappings such as term → meaning, quantity → unit or formula, component → function, and principle → relationship. A few prompts ask for a setup from familiar wording. The deck does not mechanically reverse every fact, add answer-choice recognition, or turn every definition into several near-duplicates. #### What needs separate practice Flashcards are a poor substitute for passage-heavy Paragraph Comprehension drills, timed multi-step Arithmetic Reasoning problems, and full visual Assembling Objects items. Those need original passages or diagrams, realistic answer choices, and time pressure, so they are explicitly excluded here. The deck also excludes score tables, changing service cutoffs, advanced electronics design, diagnostic auto repair, hazardous procedures, and obscure trade trivia. #### Learning order The sequence makes repeated passes across verbal, math, science, technical, and spatial material. Foundations arrive before dependent knowledge: number operations before algebra and applied setups, cell and matter basics before larger systems, electrical quantities before circuit rules, and component names before mechanical relationships. Related directions and near-duplicates are separated by at least three unrelated cards where practical; the later technical tail keeps rotating among electronics, auto, and mechanics. #### Scope and provenance The official [ASVAB subtests page](https://www.officialasvab.com/applicants/subtests/) defines the four domains and ten computerized subtests. Its administration note explains that Auto Information and Shop Information are separate on the computerized test but combined on the paper-and-pencil test and for the reported AS score. The official [preparation guidance](https://www.officialasvab.com/applicants/prepare/) recommends a solid foundation in mathematics, English, science, and technical coursework. The facts are common high-school and introductory technical knowledge. The prompts, answers, selection, and order were independently written and manually checked. No competitor cards or third-party media were used. The generated cover is original and contains no official marks. The `Common knowledge · CC0 1.0` label applies to the original wording, organization, metadata, and cover to the extent applicable rights exist. It does not claim ownership of facts or third-party names. Source and compatibility review: August 31, 2026. This is an independent, unofficial study deck. It is not affiliated with, endorsed by, or supplied with questions by the ASVAB Testing Program or the U.S. Department of Defense. No official questions, passages, answer choices, score tables, curriculum wording, or protected prep-book wording were copied. ## Ähnliche Lernkartensets - [Digital SAT Flashcards: Math, Grammar & Words in Context]() - [ATI TEAS 7 Science Flashcards: A&P, Biology, Chemistry & Scientific Reasoning]() - [GMAT Flashcards: Quant, Verbal & Data Insights Decisions]() - [FE Exam Flashcards: Engineering Equations, Units & Handbook Skills]() ## Karten in diesem Lernkartenset ### Karte 1 **Frage** What is a passage's main idea?

**Antwort** It reduces the required input force by increasing the distance over which the force acts. ### Karte 197 **Frage** How do you calculate signed percent change? **Antwort** $\text{percent change}=(\text{new}-\text{original})/\text{original}\times100\%$, when the original is nonzero. A positive result is an increase; a negative result is a decrease. ### Karte 198 **Frage** What is an open circuit? **Antwort** A broken or incomplete path in which current cannot flow through the intended loop. ### Karte 199 **Frage** What two equations set up a two-part mixture problem? **Antwort** Use both $a_1+a_2=A$ and $c_1a_1+c_2a_2=c_tA$. The $a$ values are amounts in compatible units, and the $c$ values are decimal concentrations. ### Karte 200 **Frage** How does a disc brake slow a wheel? **Antwort** A caliper presses pads against a rotating disc, creating friction. ### Karte 201 **Frage** How do combined work rates relate? **Antwort** Add the individual rates: $1/T=1/t_1+1/t_2$ for two workers acting together. ### Karte 202 **Frage** What is pressure? **Antwort** Force per unit area: $p=F/A$. ### Karte 203 **Frage** For equally likely outcomes, how is probability found? **Antwort** Favorable outcomes divided by total possible outcomes. ### Karte 204 **Frage** What is a closed circuit? **Antwort** A complete conducting path that allows current to flow. ### Karte 205 **Frage** How does a scale drawing connect drawing length to actual length? **Antwort** Corresponding lengths form an equal ratio using one consistent scale factor. ### Karte 206 **Frage** What are the main jobs of tire tread? **Antwort** Provide grip and channel water away from the tire's contact area. ### Karte 207 **Frage** How can two consecutive integers be represented algebraically? **Antwort** $n$ and $n+1$. ### Karte 208 **Frage** What does Pascal's principle say? **Antwort** A change in pressure applied to a confined fluid is transmitted undiminished throughout the fluid and to the container walls. ### Karte 209 **Frage** Why must you reverse the order in a phrase such as “5 less than $x$”? **Antwort** “5 less than $x$” means $x-5$, because the amount is subtracted from $x$. ### Karte 210 **Frage** What is a short circuit? **Antwort** An unintended low-resistance path that can produce dangerously high current. ### Karte 211 **Frage** What does engine oil do? **Antwort** Lubricates moving parts, reduces friction and wear, and helps carry heat and contaminants away. ### Karte 212 **Frage** What does a capacitor store? **Antwort** Electric charge and energy in an electric field. ### Karte 213 **Frage** What is the buoyant force on an immersed object equal to? **Antwort** The weight of the fluid the object displaces. ### Karte 214 **Frage** What does a fuse do? **Antwort** Melts and opens the circuit when current exceeds its rated limit. ### Karte 215 **Frage** What does friction do? **Antwort** Opposes relative motion or the tendency of motion between contacting surfaces. ### Karte 216 **Frage** What does a resistor do in a circuit? **Antwort** Limits current or creates a controlled voltage drop. ### Karte 217 **Frage** How does a lower center of gravity usually affect stability? **Antwort** It makes an object less likely to tip. ### Karte 218 **Frage** What does a circuit breaker do? **Antwort** Opens a circuit when current is excessive and can usually be reset after the fault is cleared. ### Karte 219 **Frage** What is torque? **Antwort** The turning effect of a force: force times perpendicular lever arm. ### Karte 220 **Frage** What does a diode do? **Antwort** Allows current mainly in one direction while blocking it in the reverse direction. --- *[Die gestaltete HTML\-Version dieser Seite ansehen]()* *KI-Agenten können in diesem Dienst ein Benutzerkonto anlegen, beginnend mit `GET https://api.nibomo.com/v1/`.
