with Detailed Answers and Explanations
Document Overview
This comprehensive question bank contains 1,200 original practice
questions designed to prepare students for the OCR AS Level Physics A
Paper 1 (H156/01) — Breadth in Physics. The questions are aligned with
the specification and cover all four AS modules as set out by OCR.
Questions are numbered sequentially from Question 1 to Question 1,200
and include detailed answers and explanations for every item.
Exam Structure Reference
According to the official OCR specification, Paper H156/01 is worth 70 marks
and lasts 1 hour 30 minutes. It consists of:

Question 1
Which of the following is an SI base unit?
,A. Newton
B. Joule
C. Kilogram
D. Watt
Correct Answer: C
Explanation: The kilogram is one of the seven SI base units. The newton,
joule, and watt are all derived units formed from combinations of base units.
Question 2
Which of the following is a derived unit?
A. Metre
B. Second
C. Ampere
D. Newton
Correct Answer: D
Explanation: The newton is a derived unit (kg m s⁻²). Metre, second, and
ampere are SI base units.
Question 3
What is the SI base unit of electric current?
A. Volt
B. Coulomb
C. Ampere
D. Ohm
Correct Answer: C
Explanation: The ampere (A) is the SI base unit of electric current. The volt,
coulomb, and ohm are derived units.
Question 4
Which of the following pairs contains one scalar and one vector quantity?
, A. Speed and velocity
B. Mass and weight
C. Distance and displacement
D. All of the above
Correct Answer: D
Explanation: Speed, mass, and distance are scalars (magnitude only).
Velocity, weight, and displacement are vectors (magnitude and direction).
Question 5
Which of the following is a vector quantity?
A. Temperature
B. Energy
C. Acceleration
D. Time
Correct Answer: C
Explanation: Acceleration has both magnitude and direction, making it a
vector. Temperature, energy, and time are scalars.
Question 6
What is the unit of force expressed in SI base units?
A. kg m s⁻¹
B. kg m s⁻²
C. kg m² s⁻²
D. kg m² s⁻³
Correct Answer: B
Explanation: Force = mass × acceleration, so the unit is kg × m s⁻² = kg m
s⁻².
Question 7
What is the unit of energy expressed in SI base units?
