WAEC Physics Practical Questions and Answers 2025
Answer all questions. Show all workings clearly.
Question 1 (Mechanics – Simple Pendulum)
You are provided with:
- A retort stand
- A string and bob
- A stopwatch
- A meter rule
(a) Measure the length (L) of the pendulum.
(b) Record the time (T) for 20 oscillations.
(c) Repeat for different lengths and complete the table:
| Length L (m) | Time for 20 Oscillations (s) | Period T (s) | T² (s²) |
|---|---|---|---|
(d) Plot a graph of T² against L.
(e) Determine the slope of the graph.
(f) Calculate the value of acceleration due to gravity (g).
Answer (Guide)
- Period: T = total time ÷ 20
- From graph: slope = ΔT² / ΔL
- Use formula:
g = (4π²) / slope
Question 2 (Electricity)
You are provided with:
- A battery
- A resistor
- An ammeter
- A voltmeter
(a) Set up a circuit as shown.
(b) Record the current (I) and voltage (V).
(c) Complete the table:
| Voltage (V) | Current (A) | Resistance (R = V/I) |
|---|---|---|
(d) Plot a graph of V against I.
(e) Determine the resistance from the graph.
Answer (Guide)
- Resistance: R = V / I
- Graph slope = Resistance
- Straight line confirms Ohm’s law
Question 3 (Optics)
You are provided with:
- A convex lens
- A screen
- A candle
(a) Place the candle at a fixed distance.
(b) Adjust the lens to form a sharp image.
(c) Measure object distance (u) and image distance (v).
(d) Complete the table:
| u (cm) | v (cm) | 1/u | 1/v |
|---|---|---|---|
(e) Determine the focal length (f).
Answer (Guide)
Use formula:
1/f = 1/u + 1/v
Calculate f from values obtained.
Question 4
(a) Define parallax error.
Answer: Error due to incorrect eye positioning when reading a scale.
(b) State two ways of avoiding it.
Answer:
- Read at eye level
- Ensure pointer and scale align properly
Question 5
(a) Name two measuring instruments and what they measure:
- Meter rule → length
- Stopwatch → time
(b) State two precautions in experiments.
Answer:
- Take accurate readings
- Avoid external interference
