The Spanish word for physics is “física,” a feminine noun pronounced “FEE-see-kah” with the stress on the first syllable.
Learning a new language requires more than just swapping one word for another. You need to understand gender, context, and the subtle differences that can change the meaning of a sentence completely. If you are a student, a traveler, or just curious about science vocabulary, getting this specific term right is fundamental.
Physics is a core subject in schools and a major field of research. In Spanish-speaking countries, you will encounter this word on class schedules, in textbook titles, and university degrees. The translation is straightforward, but the usage has a few rules you must follow to avoid confusing a science class with a physical education class or a person’s appearance.
The Main Translation And Pronunciation
The direct translation of “physics” is física. It is a feminine noun, so you will almost always see it accompanied by the article “la” (the). The spelling is very similar to English, but that accent mark on the first “i” is not optional. It dictates exactly how you say the word.
Pronunciation breakdown:
- Fee — The stress hits here. It sounds like the English word “fee.”
- See — A short, crisp “s” sound, like in “see.”
- Kah — Ends with a hard “k” sound followed by an open “a,” like in “car” but shorter.
The accent mark (tilde) over the “i” indicates that this is an esdrújula word, meaning the emphasis always falls on the third-to-last syllable. Without that emphasis, a native speaker might struggle to understand you, or you might accidentally say a different variation of the word.
Understanding The Gender: La Física vs. El Físico
Spanish grammar leans heavily on gendered nouns. This is where many English speakers trip up. In English, “physicist” and “physics” are totally different words. In Spanish, the line is thinner and depends entirely on the article and ending vowel.
1. La Física (The Science)
When you talk about the subject matter—the study of matter, energy, and motion—you use the feminine form.
- Example: Me gusta la física. (I like physics.)
- Context: School subjects, books, theories, and laws of nature.
2. El Físico (The Physicist – Male)
If you change the ending to an “o” and use the male article “el,” you are no longer talking about science. You are talking about a man who practices that science.
- Example: Él es un gran físico. (He is a great physicist.)
3. La Física (The Physicist – Female)
Context is everything here. If you use “la física” to refer to a person, you are talking about a female scientist. The spelling matches the subject name exactly, but the context of the sentence clarifies that you mean a human being.
- Example: Ella es una física famosa. (She is a famous physicist.)
4. El Físico (Physical Appearance)
To complicate things slightly, the noun “el físico” can also refer to someone’s physique or body type.
- Example: Él cuida su físico. (He takes care of his physique.)
Branches Of Physics In Spanish
Physics is a broad field. If you are studying at a university level or reading scientific papers, you will need to know the specific branches. Most of these are cognates, meaning they look and sound like their English counterparts.
Here is a breakdown of common branches you might study:
| English Branch | Spanish Translation | Pronunciation Tip |
|---|---|---|
| Mechanics | Mecánica | Stress the “cá” |
| Thermodynamics | Termodinámica | Compound word; long but phonetic |
| Quantum Physics | Física Cuántica | The “u” in Cuántica is pronounced like a “w” |
| Optics | Óptica | Strong accent on the “Ó” |
| Nuclear Physics | Física Nuclear | Nuclear sounds like “noo-cleh-AR” |
| Astrophysics | Astrofísica | Combines “astro” and “física” |
You use these terms exactly like the main noun. For example, if you want to say “I study quantum physics,” you would say “Estudio física cuántica.”
How To Say Physics In Spanish Classroom Settings
If you are a student, knowing just the word “física” is rarely enough. You need the surrounding vocabulary to survive a semester abroad or to understand a syllabus. The classroom environment has its own set of terms that appear frequently alongside the main subject.
Common classroom phrases:
- The Physics Laboratory — El laboratorio de física.
- Physics Formula — La fórmula de física.
- The Exam — El examen de física.
- Physics Homework — La tarea de física.
- The Teacher (Male/Female) — El profesor / La profesora de física.
Applying these in conversation:
When you speak to a classmate, you usually drop the formal structures. You might say, “¿Hiciste la tarea de física?” (Did you do the physics homework?). Notice that we use “de” (of) to connect the homework to the subject. In English, we treat “physics” as an adjective there (physics homework), but in Spanish, it is possessive (homework of physics).
Talking About Grades And Difficulty
Students often discuss how hard a class is. Here is how you handle that:
- Pass the class — Aprobar física.
- Fail the class — Reprobar física (Latin America) / Suspender física (Spain).
- It is hard — La física es difícil.
- It is easy — La física es fácil.
Common Mistakes And False Friends
Language learners often guess translations based on similar-sounding English words. This works often, but with “physics,” it leads to awkward errors. The most common mix-up involves the word “physical.”
Physical Education vs. Physics
In English, we shorten Physical Education to “P.E.” In Spanish, this class is called Educación Física. You do not shorten it to just “Física.” If you tell someone “Tengo clase de física,” they will expect you to be calculating velocity and mass, not running laps around a track.
Physical vs. Physics
Check the difference:
- Physics (Noun) — Física. (The science).
- Physical (Adjective) — Físico (masculine) / Física (feminine).
If you say “El mundo físico” you are saying “The physical world.” If you say “El mundo de la física,” you are saying “The world of physics.” The preposition “de” makes all the difference here.
Using The Word In Complex Sentences
Fluency comes from putting words into action. Below are several scenarios where you might use “How To Say Physics In Spanish” knowledge in real-life conversations.
Scenario A: The University Major
If you are majoring in this field, you represent your identity as a student.
- English: I am a physics major.
- Spanish: Soy estudiante de física.
Scenario B: The Career Goal
Talking about future plans involves the noun for the person, not the subject.
- English: I want to be a physicist.
- Spanish: Quiero ser físico (or física if you are female).
Scenario C: Expressing Interest
When you talk about likes and dislikes, remember that “física” is a singular noun, even though “physics” ends in an “s” in English.
- English: Physics is interesting.
- Spanish: La física es interesante.
Note that we use “es” (is), not “son” (are). Even though English speakers sometimes feel like the “s” implies plurality, it is a singular concept in both languages grammar-wise, but Spanish requires the article “La” at the start of the sentence.
How To Say Physics In Spanish Related Subjects
Physics rarely stands alone. It usually sits alongside other sciences. If you are learning the word for physics, you likely need the vocabulary for its neighbors in the science department.
The “Hard” Sciences:
- Chemistry — Química. (Key-me-kah).
- Biology — Biología. (Bee-oh-loh-hee-ah).
- Mathematics — Matemáticas. (Mah-teh-mah-tee-cas).
- Astronomy — Astronomía. (As-tro-no-me-ah).
- Geology — Geología. (Heh-oh-loh-hee-ah).
Connecting them in a sentence:
You will often see these grouped together. For example: “La física y la química son ciencias fundamentales.” (Physics and chemistry are fundamental sciences). Notice again that every subject gets its own article (la física, la química).
Etymology And Origin
Why is the word so similar in both languages? Both “physics” and “física” stem from the Greek word phusis, which means nature. The Latin term physica bridged the gap.
Because Spanish is a Romance language (derived from Latin), it kept the spelling very close to the Latin root. English also borrowed the term from Latin (via French). This shared history makes scientific vocabulary one of the easiest categories for English speakers to learn in Spanish.
Tips For Remembering The Accent Mark
We mentioned the accent mark (tilde) earlier, but we must stress its importance again. In written Spanish, omitting the accent is a spelling error. In spoken Spanish, ignoring the stress changes the rhythm of the language.
Memory aids:
- Tap the table — When you say the word, tap the table on the first syllable “FÍ”. This physical action helps lock the stress pattern into your brain.
- Visualize the slide — Imagine the word as a playground slide. You start high on “FÍ” and slide down for “si-ca”.
If you write “fisica” without the accent in a text message, people will understand you. However, if you write it that way in an academic paper or a formal email to a professor, it looks unprofessional.
Adjectives Related To Physics
Sometimes you need to describe something as relating to physics without using the noun itself. This involves using the adjectival form correctly.
- Physical Laws — Leyes físicas.
- Physical Change — Cambio físico.
- Physical Phenomenon — Fenómeno físico.
Notice the agreement. “Leyes” is feminine and plural, so the adjective is “físicas.” “Cambio” is masculine and singular, so the adjective is “físico.” This agreement matches the gender of the thing being described, not the gender of the science itself.
Why Context Matters For “Physical” vs “Physics”
Let’s look at a specific confusion point: the doctor’s office. In English, you get a “physical.” In Spanish, you do not get a “física.”
Medical Context:
- A physical exam (medical) — Un examen físico or Un chequeo médico.
- Therapy — Terapia física (Physical therapy).
If you go to a doctor and ask for “una física,” they might think you are looking for a female doctor or a female physicist. Always use “examen físico” or “chequeo” when referring to health check-ups.

Frequently Asked Questions
Is physics masculine or feminine in Spanish?
The subject itself (the science) is always feminine: la física. However, if you are referring to a person who works as a physicist, the gender changes based on the person (el físico for male, la física for female).
How do you spell physics in Spanish plural?
The plural form is físicas. You rarely use this for the science itself, but you use it often as an adjective. For example, leyes físicas means “physical laws.” The accent mark remains on the first ‘i’ in the plural form.
What is the difference between fisica and física?
The difference is the written accent mark (tilde). Física is the correct spelling with the stress on the first syllable. Fisica (without the accent) is a spelling error, though informal texts might omit it. Pronunciation requires the stress on the “Fee.”
Do you capitalize physics in Spanish?
Generally, no. Spanish does not capitalize school subjects or languages unless they are the first word of a sentence or part of a proper name (like a specific course title: “Introducción a la Física”). In general text, write it in lowercase: física.
How do you say AP Physics in Spanish?
AP classes are a specific US concept. You usually keep the “AP” or translate it as Física de Colocación Avanzada. However, most speakers just say “La clase avanzada de física” to describe the difficulty level naturally.
Wrapping It Up – How To Say Physics In Spanish
Mastering the word “física” opens the door to discussing science, education, and the natural world in Spanish. While the pronunciation is straightforward for English speakers, the real challenge lies in the grammar surrounding it.
Always remember the gender distinctions between the science and the scientist. Respect the accent mark to keep your writing professional, and pay attention to article agreement. Whether you are asking for homework help or discussing quantum mechanics, these small details will make your Spanish sound polished and accurate.
