Why You Need NECO GCE Physics Past Questions and Answers

Studying past questions is more than just memorizing answers. It helps candidates:

• Understand the exam format: Physics in NECO GCE includes objectives, theory, and calculation-based questions.

• Identify repeated topics: Some questions appear often, so students can focus revision on those areas.

• Practice problem-solving: Builds accuracy in calculations and correct use of units.

• Boost exam confidence: Knowing what to expect reduces anxiety and improves performance.

Structure of NECO GCE Physics Exam

The paper is usually divided into two main sections:

1. Section A: Objectives – Multiple-choice questions covering all areas of physics such as mechanics, heat, electricity, waves, and modern physics.

2. Section B: Theory/Calculations – Longer structured questions requiring detailed steps, derivations, and problem-solving.

Sample NECO GCE Physics 2025 Practice Questions and Answers

Section A: Objective Questions

1. Which of the following quantities is a scalar?
   A. Force
   B. Displacement
   C. Velocity
   D. Mass
   Answer: D. Mass

2. The acceleration due to gravity on Earth is approximately:
   A. 9.8 m/s²
   B. 10.0 m/s²
   C. 9.0 m/s²
   D. 8.8 m/s²
   Answer: A. 9.8 m/s²

3. A body of mass 2 kg is acted upon by a force of 10 N. What is the acceleration produced?
   Answer: Using Newton’s 2nd Law, F = ma → a = F/m = 10 ÷ 2 = 5 m/s².

4. The SI unit of electric current is:
   A. Ohm
   B. Ampere
   C. Volt
   D. Coulomb
   Answer: B. Ampere

5. Which of these is an example of renewable energy?
   A. Coal
   B. Solar
   C. Petroleum
   D. Natural gas
   Answer: B. Solar

Section B: Theory Questions

Question 1: State Ohm’s law and explain how it can be verified experimentally.

Answer Guide:

• Ohm’s law states that the current (I) through a conductor is directly proportional to the potential difference (V) across it, provided temperature remains constant.

• Formula: V = IR.

• Experiment: Set up a simple circuit with a battery, variable resistor, ammeter, and voltmeter connected across a resistor. Vary the resistance and record the corresponding V and I. A graph of V against I gives a straight line, confirming Ohm’s law.

Question 2: A stone is thrown vertically upwards with a velocity of 20 m/s. Calculate:
(a) The maximum height reached.
(b) The time taken to return to the ground.

Answer:

• (a) At maximum height, final velocity = 0. Using v² = u² – 2gh:
  0 = (20)² – 2(9.8)h → h = 400 ÷ 19.6 = 20.4 m.

• (b) Total time = 2u/g = (2 × 20) ÷ 9.8 ≈ 4.08 seconds.

Question 3: Explain three applications of electromagnetism in daily life.

Answer Guide:

• Electric bell (uses electromagnet to produce sound).

• Electric motor (converts electrical energy into mechanical energy).

• Transformers (step up or step down voltage in power supply).

Key Topics to Revise for NECO GCE Physics 2025

• Mechanics – Motion, Newton’s laws, work, energy, and power.

• Waves and Optics – Reflection, refraction, lenses, and sound waves.

• Electricity and Magnetism – Current, resistance, electromagnetism, AC/DC circuits.

• Heat and Thermodynamics – Expansion, gas laws, heat transfer.

• Modern Physics – Radioactivity, atomic models, and nuclear energy.

Exam Preparation Tips

1. Practice Calculations Daily – Physics requires solving problems, not cramming.

2. Use Past Questions Effectively – Focus on topics with repeated questions.

3. Memorize Key Formulas – Keep a formula sheet handy for daily review.

4. Show All Working Steps – In theory questions, marks are awarded for correct steps, even if the final answer is wrong.

5. Manage Your Time – Spend less time on objective questions and more on calculations.

Common Mistakes to Avoid

• Leaving out units in answers.

• Ignoring diagrams and graphical explanations.

• Copying answers without understanding the process.

• Spending too much time on one question.

Final Words

The NECO GCE Physics 2025 exam is a test of both knowledge and application. Candidates who dedicate time to practicing with past questions and answers, revising key topics, and solving numerical problems will build the confidence needed to excel. Remember, success in Physics is achieved by consistent study, discipline, and smart revision.
