General Instructions for WAEC Physics

Paper 1 (May/June, 2008–2026/2027)

• Questions in Papers A & B are framed in simple and clear language.

• Marking schemes are detailed and easy to follow.

• Papers assess candidates’ abilities to:

  1. Set up and perform simple experiments

  2. Collect and analyze data

  3. Make deductions from experiments

  4. Understand the theory behind experiments

Performance Analysis:

• Candidate performance has been consistent over the years, with average scores around 25/50.

Sample Questions & Answers

Physics Paper 1 – Experimental Procedure Example

Experiment: Centre of Gravity Using Metre Rule

Steps:

1. Suspend a metre rule on a knife edge and record the balance point, G.

2. Suspend a weight W at the 15 cm mark.

3. Suspend mass M (20 g) on the other side of G and adjust until the rule balances.

4. Record positions Y of mass M and distances L (between mass and G) and D (between W and G).

5. Repeat for M = 30, 40, 50, 60 g.

6. Tabulate L⁻¹ and corresponding values of M.

7. Plot graph of M against L⁻¹ and calculate slope s.

8. Evaluate s/D.

Section B – Theory:

• Principle of moments: sum of clockwise moments = sum of anticlockwise moments

• Centre of gravity: point through which resultant weight acts

Precautions:

• Avoid draughts

• Avoid parallax errors when reading metre rule

• Take repeated readings

Physics Paper 1 – Lens Experiment

Steps:

1. Secure metre rule on a bench; place illuminated object at 0 cm and screen at 100 cm.

2. Place a converging lens between object and screen; adjust until sharp image forms.

3. Record lens positions l1 and l2; calculate L = l1 – l2 and D = d² – L².

4. Repeat for different values of d: 85, 75, 65, 55 cm.

5. Tabulate readings, plot graph of D against d, determine slope s.

6. Evaluate k = s/4.

Section B – Theory:

• Focal length: distance between optical center and principal focus

• Real vs. virtual image: real formed by actual rays, virtual by imaginary rays

Precautions:

• Avoid parallax errors

• Align lens correctly

• Ensure vertical placement of lens

Physics Paper 2 – Projectile Motion Example

Question: A stone is projected vertically upward at 30 m/s from the top of a 50 m tower. Determine total time of flight.

Solution Steps:

1. Time to reach maximum height: t = u/g = 30/10 = 3 s

2. Maximum height: h = u²/2g = 30² / 2 × 10 = 45 m

3. Time to fall from max height: t = √(2h/g) = √(90/10) = 3 s

4. Total time of flight ≈ 6 s

Observation:

• Many candidates confused projectile from a height vs. level ground

• Some substituted values incorrectly

Physics Paper 2 – Heat & Energy Example

Question: Water of volume 200 cm³ is cooled from 20°C to –10°C. Calculate:

1. Heat extracted

2. Time taken if heat removed at 120 J/s

Solution:

1. Convert volume to mass: m = 0.2 kg

2. Q = mCΔθ + mLf + mCΔθ (for ice) = 88,200 J

3. Time: t = Q/P = 88,200 / 120 ≈ 735 s ≈ 12.25 minutes

Reason for discrepancy: Heat absorbed by container and surroundings not considered

Simple Harmonic Motion Experiment

Steps:

1. Set up two retort stands and metre rules; strings 10 cm from ends

2. Measure L, displace rule slightly, record time t for 10 oscillations

3. Determine period T, calculate log T and log L

4. Repeat for L = 70, 60, 50, 40 cm

5. Plot graph of log T against log L, determine slope and intercept

Theory:

• Simple harmonic motion: motion where acceleration is directed towards a fixed point and proportional to displacement

Precautions:

• Avoid parallax errors

• Ensure smooth, horizontal oscillations

• Note zero errors
