Physics in SSC is an application chapter. The paper rarely asks you to calculate; it asks which unit measures a quantity, which law or principle explains an everyday effect, or which device works on which principle. A straw looking bent in water, a rainbow, an echo, a fuse melting, ice skating on a thin layer of water — each is one line of theory turned into a question.

Marks are lost in three places. The first is units: base units against derived units, SI prefixes, and units of similar-sounding quantities such as power, energy and pressure. The second is mirrors, lenses and the eye: which mirror is used where, which lens corrects which defect, and what power in dioptres means. The third is standard values: the speed of sound and light, escape velocity, the value of g and temperatures on different scales. The tests here are built around exactly these three.

How Many Physics Questions Are Asked in SSC CGL?

Physics gives one or two of the 25 General Awareness questions in most SSC CGL Tier I shifts, out of the four to six that General Science gives in all. CHSL, MTS and the Tier II General Awareness paper follow the same pattern. The topics below are the ones SSC returns to most often, roughly in order.

Topic	How often	What is usually asked
Light and optics	Very frequent	Mirrors and lenses and their uses, refraction, total internal reflection, dispersion, scattering, defects of vision
Units and measurement	Very frequent	SI base and derived units, SI prefixes, units of distance in astronomy, measuring instruments
Electricity and magnetism	Frequent	Units of current, resistance and power, fuses and earthing, generators, transformers, semiconductors
Sound	Frequent	Speed of sound in different media, echo, ultrasound and infrasound, pitch and loudness, Doppler effect
Motion, force and gravitation	Frequent	Newton’s laws and their examples, momentum, friction, g, escape velocity, satellites, buoyancy
Heat	Regular	Temperature scales, thermometers, conduction, convection and radiation, latent heat, thermodynamics

Physics also overlaps with Science & Technology current affairs — ISRO missions, energy targets and new power projects are asked under both headings.

What Each Physics Test Covers

The 150 questions run through the chapter in order, 25 to a test.

Test	Topics
Test 1	Units and measurement — SI base units, scalars and vectors, dimensions, unit conversions, astronomical units, measuring instruments and SI prefixes; the universe — theories of the universe, the life cycle of stars, galaxies, the Sun, planets and moons, dwarf planets, comets and meteors, Earth’s orbit and magnetic field, space missions

The three traps that cost the most marks

Base unit or derived unit. There are only seven SI base units — metre, kilogram, second, ampere, kelvin, mole and candela. Newton, joule, watt, pascal and volt are all derived, and SSC often lists one of them among base units.
Concave or convex. A convex mirror is used as a rear-view mirror because it gives a wider field of view; a concave mirror is used in torches, headlights and by dentists. For the eye, a concave lens corrects myopia and a convex lens corrects hypermetropia.
Mass or weight. Mass stays the same everywhere; weight changes with g — it is less on the Moon and at the poles it is slightly more than at the equator. Questions on lifts, satellites and weightlessness hide this difference.

Solved Examples — SSC CGL Physics

Q1. Which of the following is NOT an SI base unit?
(a) Kelvin
(b) Candela
(c) Newton
(d) Mole

Kelvin (temperature), candela (luminous intensity) and mole (amount of substance) are three of the seven SI base units, along with the metre, kilogram, second and ampere. The newton is a derived unit of force, equal to 1 kg·m/s². Answer: (c)

Q2. Consider the following statements:
1. Sound travels faster in solids than in air.
2. Sound can travel through a vacuum.
3. The speed of sound in air increases as the temperature rises.
Which of the statements given above is/are correct?
(a) 1 and 2 only
(b) 1 and 3 only
(c) 2 and 3 only
(d) 1, 2 and 3

Sound is a mechanical wave and needs a medium, so it cannot travel through a vacuum — statement 2 is wrong. It travels fastest in solids, slower in liquids and slowest in gases, and in air it speeds up with temperature, from about 332 m/s at 0°C to about 343 m/s at 20°C. Answer: (b)

Q3. Read the Assertion (A) and Reason (R) carefully.
Assertion (A): A person standing in a lift that is accelerating downwards feels lighter.
Reason (R): In a lift accelerating downwards with acceleration a, the apparent weight of a body of mass m is m(g − a).
(a) Both A and R are true, and R is the correct explanation of A
(b) Both A and R are true, but R is not the correct explanation of A
(c) A is true, but R is false
(d) A is false, but R is true

The floor of a lift accelerating downwards pushes up on the person with a smaller force, m(g − a), so the weighing scale reads less and the person feels lighter. In free fall a = g and the apparent weight becomes zero, which is why astronauts in orbit feel weightless. R explains A. Answer: (a)

Q4. दाब का SI मात्रक क्या है?
(a) न्यूटन
(b) पास्कल
(c) जूल
(d) वाट

दाब का SI मात्रक पास्कल है; 1 पास्कल = 1 न्यूटन प्रति वर्ग मीटर। न्यूटन बल का, जूल कार्य या ऊर्जा का और वाट शक्ति का मात्रक है। समुद्र तल पर वायुमंडलीय दाब लगभग 1.01 × 10⁵ पास्कल होता है। उत्तर: (b)

How to Prepare Physics for SSC CGL

Keep one units table. Quantity – SI unit – symbol – base or derived. Add the SI prefixes from pico to tera. This single page answers a large share of SSC physics questions.
Learn every law with one everyday example. Inertia and the jerk in a bus, Newton’s third law and a rocket, Bernoulli and an aeroplane wing, total internal reflection and optical fibres — SSC asks the example, not the statement.
Remember a short list of values. Speed of light 3 × 10⁸ m/s, speed of sound in air about 343 m/s, g about 9.8 m/s², escape velocity 11.2 km/s, −40° equal on the Celsius and Fahrenheit scales.
Read the solutions, not just the answer. Each solution here carries six or seven related facts — reading them is how 150 questions cover the whole chapter.
Check yourself on real questions. One test a day keeps the earlier topics fresh while you move ahead, and the Physics previous year questions show exactly how SSC words them.

SSC CGL Physics — Frequently Asked Questions

How many Physics questions are asked in SSC CGL?

Usually one or two of the 25 General Awareness questions in an SSC CGL Tier I shift. General Science as a whole gives four to six, and physics is the part most often asked as everyday applications. CHSL, MTS and the Tier II General Awareness paper follow the same pattern.

Which Physics topics are most important for SSC?

Units and SI prefixes, light and the human eye, sound, electricity and magnetism come up most often, followed by laws of motion, gravitation and satellites, heat and thermometers, and inventions and discoveries.

How many tests and questions are in this chapter?

Six tests of 25 questions each, 150 questions in all, in chapter order: units and the universe, motion and energy, gravitation and energy resources, electricity and magnetism, sound and light, and heat and thermodynamics. No fact is asked twice.

Are the Physics tests available in Hindi?

Yes. Every test is available in both English and Hindi with the same questions and the same answer key, and you choose the language when you start the test.

Do the tests need calculations?

Very few. SSC asks physics mostly as concepts, units, laws and applications, so the tests do the same; where a value is needed, such as escape velocity or the speed of sound, it is a standard figure you are expected to remember.

What do the solutions contain?

Six to seven short points for every question: the answer, the law or principle behind it, the related units, values and applications, and what each wrong option actually refers to.

Is there a timer, and what is the marking scheme?

An optional 15-minute timer per test, and the real exam marking of +2 for a correct answer, −0.5 for a wrong one and 0 for an unattempted question.

Are the Physics tests free?

Yes, every test is free. You need a free TrickySSC account to start one — sign in once with Google or your mobile number and every test is open to you.
