JAMB Physics 2016 past questions
6 objective questions from the 2016 JAMB Physics paper. Answer each one, then reveal the answer and explanation.
Question 1
PressureA force of 500 N acts on an area of 5 m². Find the pressure exerted.
- Option A: 2,500 Pa
- Option B: 50 Pa
- Option C: 200 Pa
- Option D: 100 Pa
Show the answerHide the answer to question 1
Answer: D, 100 Pa
Pressure = force ÷ area = 500 ÷ 5 = 100 Pa.
Question 2
Current electricityA potential difference of 16.5 V is applied across a 11 Ω resistor. Find the current that flows.
- Option A: 181.5 A
- Option B: 0.67 A
- Option C: 3 A
- Option D: 1.5 A
Show the answerHide the answer to question 2
Answer: D, 1.5 A
By Ohm's law, I = V ÷ R = 16.5 ÷ 11 = 1.5 A.
Question 3
Work and energyCalculate the kinetic energy of a 2 kg body moving at 4 m/s.
- Option A: 32 J
- Option B: 4 J
- Option C: 16 J
- Option D: 8 J
Show the answerHide the answer to question 3
Answer: C, 16 J
KE = ½mv² = ½ × 2 × 4² = 16 J.
Question 4
WavesA wave of frequency 350 Hz has a wavelength of 6 m. Find its speed.
- Option A: 2100 m/s
- Option B: 58.33 m/s
- Option C: 0.0171 m/s
- Option D: 4200 m/s
Show the answerHide the answer to question 4
Answer: A, 2100 m/s
v = fλ = 350 × 6 = 2100 m/s.
Question 5
MotionA car moving at 4 m/s accelerates uniformly at 3 m/s² for 4 s. Find its final velocity.
- Option A: 15 m/s
- Option B: 7 m/s
- Option C: 16 m/s
- Option D: 32 m/s
Show the answerHide the answer to question 5
Answer: C, 16 m/s
Use v = u + at = 4 + 3 × 4 = 16 m/s.
Question 6
Units and measurementWhat is the SI unit of frequency?
- Option A: Hertz
- Option B: Second
- Option C: Metre
- Option D: Decibel
Show the answerHide the answer to question 6
Answer: A, Hertz
Frequency is measured in hertz (Hz), cycles per second.
