OCR A Level Physics A Paper 1 2025 Question Paper

Download the official OCR A Level Physics A H556/01 Modelling Physics question paper from the June 2025 examination series. This downloadable PDF contains the complete OCR A Level Physics A Paper 1 exam sat on Friday 23 May 2025, including multiple-choice questions, graph-analysis tasks, practical-investigation problems, calculations, uncertainty evaluation, and extended-response Physics questions in the official OCR exam format.
The OCR H556/01 June 2025 question paper covers a broad range of advanced A Level Physics A topics including specific heat capacity, inelastic collisions, moments and equilibrium, simple harmonic motion, projectile motion, diffraction gratings, circular motion, gravitation, stellar evolution, cosmology, momentum, oscillations, thermal physics, latent heat, ideal gases, Kepler’s laws, Hubble’s law, absorption spectra, and astrophysics calculations.
Section A contains multiple-choice questions testing conceptual understanding, mathematical Physics skills, graph interpretation, and advanced problem solving. Topics include SI base units, heating efficiency, collisions, spring systems, state changes, momentum transfer between walls, stellar parallax, centripetal force, gravitational attraction, stellar evolution, diffraction gratings, Wien’s displacement law, SHM behaviour, and cosmological principles.

Question 16 investigates the motion of an electric car under constant motor force. Students analyse velocity-time and force-time graphs, estimate distance travelled from graphical methods, determine acceleration and change in momentum, explain resistive-force behaviour, apply Newton’s third law to frictional thrust, and calculate resultant force and driving force during acceleration.

Question 17 explores projectile motion using an aircraft experiencing apparent weightlessness. Students calculate time of flight, determine resultant velocity and angle, explain why thrust is still required during projectile motion, analyse gravitational field strength at altitude, and explain why passengers appear weightless despite Earth’s gravity still acting.

Question 18 focuses on a floating cylindrical wave-energy generator. Students apply Archimedes’ principle, calculate displacement depth, explain equilibrium conditions, derive restoring-force equations, demonstrate simple harmonic motion, determine natural frequency, and evaluate machine designs using resonance behaviour and ripple-tank investigations.

Question 19 investigates thermal energy transfer and evaporation in a liquid-oxygen storage tank. Students explain latent heat and particle-energy changes, calculate evaporation rates, determine volume changes, and apply ideal-gas equations to calculate gas pressure inside the tank.

Question 20 analyses the relationship between specific heat capacity and particle number density in noble gases. Students complete missing data, plot graphs, determine trends, and explain the relationship between particle count and thermal-energy storage.

Question 21 is an extended-response astrophysics task comparing the absorption spectra of Vega and Tau Ceti. Students explain the formation of dark absorption lines, analyse spectral differences, evaluate stellar composition and temperature, and determine which star is older using evidence from stellar spectra.

Question 22 explores orbital mechanics using an asteroid orbiting the Sun. Students apply Kepler’s third law, calculate orbital period and kinetic energy, analyse changes in gravitational potential energy, and explain features of elliptical orbits according to Kepler’s first law.

Question 23 focuses on redshift and cosmology using the galaxy M87. Students calculate recession velocity from hydrogen-alpha spectral lines, estimate galactic distance using Hubble’s law, determine uncertainty from emission-line width, evaluate deviations from Hubble’s law, and explain why the Big Bang model remains scientifically accepted.
