Physics Questions for RRB ALP, Download Free PDF

Do you dream of sitting in the driver’s cabin and driving the massive trains of Indian Railways? If yes, you need first to clear the Computer-Based Test (CBT 1). Most students preparing for the ALP exam have a technical or science background (ITI, Diploma, or B.Tech). Even then, many students find the General Science section, especially Physics, very boring and difficult. You might think that learning all the tough formulas and theories is not possible, but RRB does not ask tough questions. They only ask very basic, famous, and repeated questions from 10th-level textbooks. In this blog, we have provided exam-level physics questions for RRB ALP exam that you can get for free. And, along with that, we have provided free physics tests that will help you know how the exam is being conducted.

What to Study in Physics for RRB ALP?

You do not need to read thick engineering books to pass this section. The Railway Board only wants to check your basic general science knowledge about daily life. You can divide the whole syllabus into four simple parts:

• Units and Measurements: This is the easiest part. Just memorize what is used to measure what, like force is measured in Newtons and power in Watts.
• Motion and Work: Focus on basic things like speed, velocity, and acceleration. Read about what work, energy, and power actually mean in real life.
• Light and Sound: This is a very scoring part. Learn the difference between mirrors and lenses, and read about how sound travels.
• Basic Electricity: Since you are applying for an ALP post, this is very important. Read simple concepts like voltage, current, resistance, and Ohm’s law.

If you just focus on these basic topics, Physics will become your scoring subject.

Important Physics Questions for RRB ALP, Download Free PDF

Below, we have provided some exam-level physics questions for the RRB ALP exam. Practicing these will help you test your preparation. Also, we have provided a PDF that you can download for free with many more questions.

Q1. What is the SI unit of Force?

(A) Joule
(B) Newton
(C) Watt
(D) Pascal

Answer: (B) Newton

Explanation:
Force is measured in Newtons.
Joule is the unit of Energy, Watt is the unit of Power, and Pascal is used to measure Pressure.

Q2. Which instrument is used to measure electric current in a circuit?

(A) Voltmeter
(B) Galvanometer
(C) Ammeter
(D) Barometer

Answer: (C) Ammeter

Explanation:
An Ammeter is used to measure electric current and it is always connected in series in a circuit.

Q3. Which type of mirror is used as a rear-view mirror in vehicles?

(A) Plane Mirror
(B) Concave Mirror
(C) Convex Mirror
(D) Cylindrical Mirror

Answer: (C) Convex Mirror

Explanation:
Convex mirrors provide a wider field of view and make objects appear smaller, helping drivers see more area behind them.

Q4. Why does the sky appear blue during the daytime?

(A) Reflection of light
(B) Refraction of light
(C) Scattering of light
(D) Dispersion of light

Answer: (C) Scattering of light

Explanation:
Tiny particles in the atmosphere scatter blue light from the sun more than other colors because blue light has a shorter wavelength.

Q5. Sound waves cannot travel through which medium?

(A) Solid
(B) Liquid
(C) Gas
(D) Vacuum

Answer: (D) Vacuum

Explanation:
Sound waves require a material medium (solid, liquid, or gas) to travel. In a vacuum there are no particles, so sound cannot propagate.

Q6. What is the rate of change of velocity called?

(A) Speed
(B) Momentum
(C) Force
(D) Acceleration

Answer: (D) Acceleration

Explanation:
Acceleration is the rate at which velocity changes with respect to time.

Q7. The energy possessed by a body due to its motion is called:

(A) Potential Energy
(B) Kinetic Energy
(C) Chemical Energy
(D) Heat Energy

Answer: (B) Kinetic Energy

Explanation:
Any moving object, such as a running train or flying bird, possesses kinetic energy.

Q8. Ohm is the SI unit of which physical quantity?

(A) Electric Current
(B) Voltage
(C) Electrical Resistance
(D) Power

Answer: (C) Electrical Resistance

Explanation:
Electrical resistance is measured in Ohms. Resistance opposes the flow of electric current.

Q9. What are the primary colors of light?

(A) Red, Yellow, Blue
(B) Red, Green, Blue
(C) Orange, Green, Violet
(D) Red, White, Black

Answer: (B) Red, Green, Blue

Explanation:
In physics, the primary colors of light are Red, Green, and Blue. These can combine to produce other colors on screens.

Q10. Which device converts mechanical energy into electrical energy?

(A) Electric Motor
(B) Transformer
(C) Dynamo (Generator)
(D) Battery

Answer: (C) Dynamo (Generator)

Explanation:
A generator or dynamo converts mechanical energy into electrical energy.

5 Simple Tips to Prepare for Physics for RRB ALP

You do not have the time to read thick science books, and honestly, you do not need to. Here are 5 smart and easy tips to cover this topic quickly:

• Memorize the SI Units Chart: Railway exams love asking about units. Make a simple list of basic units (like Work, Power, Force) and stick it on your wall.
• Focus on Daily Life Examples: Stop trying to memorize tough definitions. Read about real-life examples, like why a pencil looks bent in a glass of water.
• Remember Basic Formulas: You do not need to solve long mathematical problems. Just remember small formulas like Speed = Distance/Time. They only ask one-step numericals.
• Use 10th Standard Books: Do not buy heavy competitive exam books. A simple 10th-level NCERT summary is more than enough for this exam.
• Practice Previous Year Papers: Railway exam questions mostly match with each other’s science questions. Solve the previous year’s physics questions of RRB Group D, NTPC, and ALP. You will see the same patterns repeating!
