WAEC 2026 Physics Questions and Answers (OBJ & Essay) – May/June ESSAY QUESTIONS AND ANSWERS (1–20)
1. Define force and state its unit.
Answer: Force is any push or pull acting on a body that can change its state of motion. Its SI unit is Newton (N).
2. State Newton’s First Law of Motion.
Answer: A body remains at rest or in uniform motion in a straight line unless acted upon by an external force.
3. What is energy?
Answer: Energy is the ability to do work.
4. Differentiate between mass and weight.
Answer:
- Mass is the amount of matter in a body (constant).
- Weight is the force due to gravity acting on a body (varies with location).
5. Define velocity.
Answer: Velocity is the rate of change of displacement with time.
6. State Ohm’s Law.
Answer: The current flowing through a conductor is directly proportional to the voltage across it, provided temperature remains constant.
7. What is power?
Answer: Power is the rate at which work is done.
8. Define acceleration.
Answer: Acceleration is the rate of change of velocity with time.
9. What is refraction of light?
Answer: Refraction is the bending of light as it passes from one medium to another.
10. List three types of energy.
Answer:
- Kinetic energy
- Potential energy
- Chemical energy
11. Define pressure.
Answer: Pressure is the force applied per unit area.
12. What is a wave?
Answer: A wave is a disturbance that transfers energy from one point to another without transfer of matter.
13. State the law of conservation of energy.
Answer: Energy cannot be created or destroyed but can be transformed from one form to another.
14. What is temperature?
Answer: Temperature is the degree of hotness or coldness of a body.
15. Define density.
Answer: Density is mass per unit volume of a substance.
16. What is an electric circuit?
Answer: An electric circuit is a closed path through which electric current flows.
17. Mention two types of mirrors.
Answer:
- Concave mirror
- Convex mirror
18. Define frequency.
Answer: Frequency is the number of oscillations per second.
19. What is magnetism?
Answer: Magnetism is the force of attraction or repulsion between magnetic materials.
20. Explain conduction.
Answer: Conduction is the transfer of heat through a material without movement of the material itself.
