ASVAB Flashcards: Verbal, Math, Science & Technical Review

Review the facts worth recalling before you spend time on full practice questions. 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 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 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.

Antwort
Opposite directions.
Karte 188
Frage
What does candid mean?
Antwort
Honest and direct.
Karte 189
Frage
How do corresponding lengths compare in similar figures?
Antwort
They share one scale factor; corresponding angles stay equal.
Karte 190
Frage
How does voltage behave across branches of an ideal parallel circuit?
Antwort
Each branch has the same voltage as the source.
Karte 191
Frage
What equation links distance, rate, and time?
Antwort
$d=rt$ .
Karte 192
Frage
What does a differential let driven wheels do?
Antwort
Rotate at different speeds while still receiving torque.
Karte 193
Frage
What is the simple-interest formula?
Antwort
$I=Prt$ , where $P$ is principal, $r$ is the decimal annual rate, and $t$ is time in years.
Karte 194
Frage
What does a bench vise do?
Antwort
Holds a workpiece firmly while it is cut, filed, drilled, or assembled.
Karte 195
Frage
How do you find a unit rate?
Antwort
Divide to express the quantity per one unit.
Karte 196
Frage
How does an inclined plane trade force for distance?
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

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

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.
