Sample WAEC Physics Past Questions with Answers
1. Measurement and Units
Question: Define a metre and state one method of measuring it accurately.
(WAEC 2023)
Answer:
A metre is the distance traveled by light in a vacuum in 1/299,792,458 seconds. It can be measured using a metre rule or tape.
2. Motion
Question: A car accelerates from rest at 2 m/s² for 5 seconds. Calculate its final velocity.
(WAEC 2022)
Answer:
Using v=u+at:
v=0+2×5=10 m/s
3. Heat Energy
Question: Define specific heat capacity and state its SI unit.
(WAEC 2021)
Answer:
Specific heat capacity is the amount of heat required to raise the temperature of 1kg of a substance by 1°C (or 1K). SI unit: J/kg·K
4. Electricity
Question: State Ohm’s Law.
(WAEC 2020)
Answer:
Ohm’s Law states that the current flowing through a conductor is directly proportional to the voltage across it, provided the temperature remains constant:
V=IR
5. Simple Machines
Question: Define mechanical advantage (M.A) and velocity ratio (V.R).
(WAEC 2019)
Answer:
-
M.A = Load / Effort
-
V.R = Distance moved by effort / Distance moved by load
WAEC Physics Practical Topics That Repeat Often
| Experiment | Why It Matters |
|---|---|
| Determination of Acceleration due to Gravity | Appears almost every year |
| Hooke’s Law (Spring Constant) | Frequent in recent years |
| Ohm’s Law Practical | Highly predictable and easy |
| Simple Pendulum | Always tested in practical paper |
| Heat (Mixture and Calorimetry) | Common in thermal energy tests |
