2024_OCR: AS Level Physics A H156/01 Breadth in Physics
(Merged Question Paper & Marking Scheme)
Key Areas to Revise:
1. Measurement and Units
o Fundamental Quantities: Understand the SI units for length, mass, time, temperature,
electric current, amount of substance, and luminous intensity. Be familiar with the
definitions and relationships between these units.
o Precision and Accuracy: Learn about significant figures, uncertainties in measurements,
and how to calculate absolute and percentage uncertainties.
o Standard Form: Practice working with numbers in standard form, especially when
dealing with very large or small values in physics contexts.
2. Forces and Motion
o Kinematics: Revise the key concepts of motion, including displacement, velocity,
acceleration, and the relationships between them. Practice solving problems involving
constant acceleration, such as using the SUVAT equations.
o Forces and Newton’s Laws: Study Newton's laws of motion and how to apply them to
solve problems involving forces, friction, tension, and motion of objects. Understand
concepts like weight, normal force, and frictional force.
o Momentum: Understand the principle of conservation of momentum in elastic and
inelastic collisions. Study how momentum is related to force and time, and how to apply
the impulse-momentum theorem.
3. Energy
o Work, Energy, and Power: Revise the definitions of work, kinetic energy, gravitational
potential energy, and elastic potential energy. Be familiar with the law of conservation of
energy and how to apply it in different contexts.
o Power: Understand the definition of power as the rate of doing work or transferring
energy, and be able to solve problems involving power in mechanical and electrical
contexts.
o Energy Transformations: Study the different forms of energy (kinetic, potential, thermal,
etc.) and how energy is transferred and transformed in various physical systems.
4. Waves
o Wave Properties: Understand the key properties of waves, such as frequency,
wavelength, amplitude, and speed. Be familiar with the difference between transverse and
longitudinal waves and how to represent waves graphically.
o Wave Behavior: Study the phenomena of reflection, refraction, diffraction, and
interference. Learn how to apply Snell's law and the principles of superposition to solve
wave-related problems.
o Sound and Light Waves: Investigate the properties of sound waves (including the
Doppler effect) and light waves (including reflection, refraction, and diffraction through
various materials).
5. Electricity
, o Electric Current and Circuit Components: Understand the flow of electric charge, the
relationship between current, voltage, and resistance (Ohm’s law), and how to analyze
simple circuits using series and parallel arrangements.
o Electrical Power: Revise the formulae for electrical power (P = IV, P = I²R, and P = V²/R)
and apply them to solve problems in circuits.
o Electromotive Force (EMF) and Internal Resistance: Study how to calculate the EMF
of a source and how internal resistance affects the performance of electrical devices.
6. Atomic and Nuclear Physics
o Atomic Structure: Understand the structure of atoms, including protons, neutrons, and
electrons. Study the concept of energy levels, electron transitions, and the emission and
absorption spectra of atoms.
o Radioactivity: Revise the types of radiation (alpha, beta, and gamma), their properties,
and how they interact with matter. Understand half-life calculations and the concept of
nuclear decay.
o Nuclear Reactions: Study the process of nuclear fission and fusion, the energy released in
these processes, and the applications of nuclear energy.
7. Thermal Physics
o Temperature and Heat: Understand the difference between temperature and heat. Study
the laws of thermodynamics, and the relationship between thermal energy and temperature
changes.
o Ideal Gas Laws: Revise the ideal gas law (PV = nRT), and understand how to use it to
solve problems involving pressure, volume, and temperature of gases.
o Specific Heat Capacity and Latent Heat: Study how substances absorb heat and change
temperature or phase. Understand specific heat capacity, latent heat, and how to calculate
the heat energy required for temperature and phase changes.
