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.

پاسخ
Opposite directions.
کارت ۱۸۸
پرسش
What does candid mean?
پاسخ
Honest and direct.
کارت ۱۸۹
پرسش
How do corresponding lengths compare in similar figures?
پاسخ
They share one scale factor; corresponding angles stay equal.
کارت ۱۹۰
پرسش
How does voltage behave across branches of an ideal parallel circuit?
پاسخ
Each branch has the same voltage as the source.
کارت ۱۹۱
پرسش
What equation links distance, rate, and time?
پاسخ
$d=rt$ .
کارت ۱۹۲
پرسش
What does a differential let driven wheels do?
پاسخ
Rotate at different speeds while still receiving torque.
کارت ۱۹۳
پرسش
What is the simple-interest formula?
پاسخ
$I=Prt$ , where $P$ is principal, $r$ is the decimal annual rate, and $t$ is time in years.
کارت ۱۹۴
پرسش
What does a bench vise do?
پاسخ
Holds a workpiece firmly while it is cut, filed, drilled, or assembled.
کارت ۱۹۵
پرسش
How do you find a unit rate?
پاسخ
Divide to express the quantity per one unit.
کارت ۱۹۶
پرسش
How does an inclined plane trade force for distance?
پاسخ
It reduces the required input force by increasing the distance over which the force acts.
کارت ۱۹۷
پرسش
How do you calculate signed percent change?
پاسخ
$\text{percent change}=(\text{new}-\text{original})/\text{original}\times100\%$ , when the original is nonzero. A positive result is an increase; a negative result is a decrease.
کارت ۱۹۸
پرسش
What is an open circuit?
پاسخ
A broken or incomplete path in which current cannot flow through the intended loop.
کارت ۱۹۹
پرسش
What two equations set up a two-part mixture problem?
پاسخ
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.
کارت ۲۰۰
پرسش
How does a disc brake slow a wheel?
پاسخ
A caliper presses pads against a rotating disc, creating friction.
کارت ۲۰۱
پرسش
How do combined work rates relate?
پاسخ
Add the individual rates: $1/T=1/t_1+1/t_2$ for two workers acting together.
کارت ۲۰۲
پرسش
What is pressure?
پاسخ
Force per unit area: $p=F/A$ .
کارت ۲۰۳
پرسش
For equally likely outcomes, how is probability found?
پاسخ
Favorable outcomes divided by total possible outcomes.
کارت ۲۰۴
پرسش
What is a closed circuit?
پاسخ
A complete conducting path that allows current to flow.
کارت ۲۰۵
پرسش
How does a scale drawing connect drawing length to actual length?
پاسخ
Corresponding lengths form an equal ratio using one consistent scale factor.
کارت ۲۰۶
پرسش
What are the main jobs of tire tread?
پاسخ
Provide grip and channel water away from the tire's contact area.
کارت ۲۰۷
پرسش
How can two consecutive integers be represented algebraically?
پاسخ
$n$ and $n+1$ .
کارت ۲۰۸
پرسش
What does Pascal's principle say?
پاسخ
A change in pressure applied to a confined fluid is transmitted undiminished throughout the fluid and to the container walls.
کارت ۲۰۹
پرسش
Why must you reverse the order in a phrase such as “5 less than $x$ ”?
پاسخ
“5 less than $x$ ” means $x-5$ , because the amount is subtracted from $x$ .
کارت ۲۱۰
پرسش
What is a short circuit?
پاسخ
An unintended low-resistance path that can produce dangerously high current.
کارت ۲۱۱
پرسش
What does engine oil do?
پاسخ
Lubricates moving parts, reduces friction and wear, and helps carry heat and contaminants away.
کارت ۲۱۲
پرسش

پاسخ
Melts and opens the circuit when current exceeds its rated limit.
کارت ۲۱۵
پرسش
What does friction do?
پاسخ
Opposes relative motion or the tendency of motion between contacting surfaces.
کارت ۲۱۶
پرسش
What does a resistor do in a circuit?
پاسخ
Limits current or creates a controlled voltage drop.
کارت ۲۱۷
پرسش
How does a lower center of gravity usually affect stability?
پاسخ
It makes an object less likely to tip.
