Physics, with its combination of theoretical understanding and practical applications, requires a deep understanding of core principles, scientific reasoning, and problem-solving skills.
For many students, the multiple-choice (Objective) section and the essay-based questions in the WAEC Physics exam can seem daunting. However, with focused preparation and an understanding of the types of questions that may appear, students can significantly improve their chances of success. This blog post offers a guide to help you prepare for the WAEC Physics exam by highlighting possible objective and essay questions. This guide will also provide insights into what you need to focus on in each section of the exam.
Understanding WAEC Physics (Obj & Essay) Questions and Answers 2026/2027
The WAEC Physics exam is typically divided into two main sections:
- Objective Section (Obj): This section consists of multiple-choice questions (MCQs) that test your understanding of the fundamental principles of Physics. The questions are usually straightforward and cover a wide range of topics. Students must carefully read each question and choose the best answer from the options provided.
- Essay Section: The essay section requires students to provide in-depth written answers. This section is more focused on testing a student’s ability to apply theoretical knowledge to practical scenarios. These questions are often broader and may require you to explain concepts, derive equations, and solve problems that include diagrams or calculations.
In this post, we will cover possible questions for both sections of the exam, providing a comprehensive guide for your preparation.
WAEC Physics Objective (Obj) Questions
The objective questions in the WAEC Physics exam are designed to test your recall of key facts, concepts, and principles. These questions are usually fairly straightforward but require a solid grasp of the syllabus and understanding of the fundamental principles of Physics. Here are some examples of potential questions you might encounter:
1. Kinematics and Motion
- Question: Which of the following is a vector quantity?
a) Speed
b) Distance
c) Displacement
d) Time
Answer: c) Displacement
Explanation: Displacement is a vector quantity because it has both magnitude and direction, unlike speed and distance, which are scalar quantities.
- Question: The acceleration of an object is given by:
a) The change in velocity over time
b) The speed of the object
c) The distance traveled over time
d) The force exerted on the object
Answer: a) The change in velocity over time
Explanation: Acceleration is defined as the rate of change of velocity with respect to time.
2. Force and Motion
- Question: What is the unit of force in the International System of Units (SI)?
a) Newton
b) Joule
c) Watt
d) Pascal
Answer: a) Newton
Explanation: The SI unit of force is the Newton (N), named after Sir Isaac Newton, and it is defined as the force required to accelerate a one-kilogram mass by one meter per second squared.
- Question: If the mass of an object is 5 kg and it is subjected to a force of 20 N, what is its acceleration?
a) 4 m/s²
b) 5 m/s²
c) 2 m/s²
d) 10 m/s²
Answer: a) 4 m/s²
Explanation: Using Newton’s second law of motion, ( F = ma ), the acceleration ( a = \frac{F}{m} = \frac{20}{5} = 4 , \text{m/s}^2 ).
3. Work, Energy, and Power
- Question: Which of the following formulas represents the relationship between work and energy?
a) Work = Force × Distance
b) Energy = Mass × Acceleration
c) Power = Work ÷ Time
d) None of the above
Answer: a) Work = Force × Distance
Explanation: The formula for work done is the product of the force applied and the distance moved in the direction of the force. Work and energy are closely related as they both involve the transfer or conversion of energy.
- Question: What is the SI unit of power?
a) Joule
b) Watt
c) Newton
d) Meter
Answer: b) Watt
Explanation: The SI unit of power is the Watt (W), which is defined as the rate of doing work or the rate of energy transfer. One watt is equal to one joule per second.
4. Thermodynamics
- Question: In an ideal gas, which of the following remains constant during an isothermal process?
a) Volume
b) Pressure
c) Temperature
d) Internal energy
Answer: c) Temperature
Explanation: An isothermal process occurs at a constant temperature. During this process, the temperature of the gas remains unchanged, even though the volume and pressure may vary.
5. Electricity and Magnetism
- Question: The resistance of a conductor is most affected by:
a) Its length
b) Its color
c) Its temperature
d) Its mass
Answer: c) Its temperature
Explanation: The resistance of a conductor is highly dependent on its temperature. As the temperature of the conductor increases, the resistance typically increases as well.
WAEC Physics Essay Questions
The essay section of the WAEC Physics exam tests your ability to apply theoretical knowledge to practical scenarios. Below are some sample essay questions that could appear in the exam. These questions will require you to provide explanations, derive equations, and often include diagrams or calculations.
1. Kinematics
- Question: Explain the terms “displacement” and “velocity” with the aid of appropriate diagrams. Also, derive an expression for the distance covered by an object moving with constant acceleration.
Answer Outline:
- Define displacement (a vector quantity) and velocity (rate of change of displacement).
- Use diagrams to show the difference between distance and displacement.
- Derive the equation of motion for distance covered under constant acceleration: ( s = ut + \frac{1}{2}at^2 ), where:
- ( u ) = initial velocity,
- ( a ) = acceleration,
- ( t ) = time,
- ( s ) = distance.

2. Force and Laws of Motion
- Question: State and explain Newton’s three laws of motion. With examples, describe how each law is applied in everyday life.
Answer Outline:
- First Law (Law of Inertia): Objects at rest stay at rest, and objects in motion stay in motion unless acted upon by an external force. Example: A car continues moving until the brakes are applied.
- Second Law (F = ma): The force on an object is the product of its mass and acceleration. Example: A heavier object requires more force to move than a lighter object.
- Third Law (Action and Reaction): For every action, there is an equal and opposite reaction. Example: When you push on a wall, the wall pushes back with the same force.
3. Energy Transformation
- Question: Discuss the law of conservation of energy. Provide an example where mechanical energy is converted to other forms of energy, and explain the process.
Answer Outline:
- Law of Conservation of Energy: Energy cannot be created or destroyed, only transformed from one form to another.
- Example: In a rollercoaster, potential energy at the highest point is converted to kinetic energy as it moves down, and later transformed to heat and sound energy due to friction.
4. Wave Properties
- Question: Define the terms frequency, amplitude, and wavelength. Using diagrams, explain how sound waves travel through different mediums, highlighting their properties and the effect of temperature on the speed of sound.
Answer Outline:
- Define frequency, amplitude, and wavelength.
- Use diagrams to show how sound waves move through air, water, and solids.
- Discuss how sound waves travel faster in solids and liquids compared to air due to the density and elasticity of the medium.
- Explain how temperature affects sound speed: higher temperatures increase sound speed as the molecules move faster.
5. Electricity and Magnetism
- Question: State Ohm’s Law and explain its significance in the analysis of electrical circuits. Draw and label a simple series circuit, showing how the current and voltage are distributed.
Answer Outline:
- Ohm’s Law: ( V = IR ), where ( V ) is voltage, ( I ) is current, and ( R ) is resistance.
- Explain how Ohm’s Law helps to understand the relationship between current, voltage, and resistance.
- Draw a simple series circuit with resistors and show how the current remains the same across all components, while voltage is divided.
