All WAEC Physics past questions

  1. Question 1

    Work and energy

    Calculate the kinetic energy of a 15 kg body moving at 6 m/s.

    1. Option A: 540 J
    2. Option B: 270 J
    3. Option C: 45 J
    4. Option D: 90 J
    Show the answer to question 1

    Answer: B, 270 J

    KE = ½mv² = ½ × 15 × 6² = 270 J.

  2. Question 2

    Heat

    How much heat is needed to raise the temperature of 4 kg of water by 10 °C? (Specific heat capacity of water = 4200 J/kg K.)

    1. Option A: 84,000 J
    2. Option B: 16,800 J
    3. Option C: 42,000 J
    4. Option D: 168,000 J
    Show the answer to question 2

    Answer: D, 168,000 J

    Q = mcΔθ = 4 × 4200 × 10 = 168,000 J.

  3. Question 3

    Waves

    A wave of frequency 500 Hz has a wavelength of 2.5 m. Find its speed.

    1. Option A: 1250 m/s
    2. Option B: 200 m/s
    3. Option C: 0.005 m/s
    4. Option D: 2500 m/s
    Show the answer to question 3

    Answer: A, 1250 m/s

    v = fλ = 500 × 2.5 = 1250 m/s.

  4. Question 4

    Current electricity

    A potential difference of 3.4 V is applied across a 17 Ω resistor. Find the current that flows.

    1. Option A: 57.8 A
    2. Option B: 0.2 A
    3. Option C: 5 A
    4. Option D: 0.4 A
    Show the answer to question 4

    Answer: B, 0.2 A

    By Ohm's law, I = V ÷ R = 3.4 ÷ 17 = 0.2 A.

  5. Question 5

    Density

    A sample of mass 72 g occupies a volume of 60 cm³. Calculate its density.

    1. Option A: 0.83 g/cm³
    2. Option B: 12 g/cm³
    3. Option C: 0.6 g/cm³
    4. Option D: 1.2 g/cm³
    Show the answer to question 5

    Answer: D, 1.2 g/cm³

    Density = mass ÷ volume = 72 ÷ 60 = 1.2 g/cm³.
