Daniel turned to the stack of 2024 Paper 4. Question 6(b): A satellite in geostationary orbit experiences a small drag force due to solar wind. Explain, using energy considerations, why its orbital radius decreases. He scribbled an answer: Drag does work against satellite, reduces total energy, so it spirals inward. Two lines. The mark scheme, which he’d printed from the examiner’s report, wanted four distinct points: recognition of negative work, loss of total mechanical energy, conversion to internal energy, and the specific relationship between orbital radius and total energy (E = -GMm/2r). Two marks lost. Again.

The past papers had done their job. They weren’t just relics of exams gone by. They were the ghost of the examiner, whispering warnings from every previous mistake. And finally—finally—he had learned to listen. past papers a level physics

Daniel glanced at the 2022 Paper 5. Question 2: Design an experiment to determine the Young modulus of a wire made of an unknown alloy, using only a laser, a screen, a ruler, and a mass hanger. No standard apparatus. No micrometer for the wire’s diameter. The laser was a red herring—or was it? He’d spent forty minutes on that question before realizing you could measure the wire’s extension via diffraction pattern from a hair-thin wire, turning a materials problem into a wave problem. The examiner’s note: “Candidates who recognized the diffraction method scored highly. Most did not.” Daniel turned to the stack of 2024 Paper 4

The paper landed on his desk. He flipped through it calmly. Question 2: a satellite losing energy due to atmospheric drag. He smiled. Question 5: an alpha decay calculation. He checked the units—MeV to joules—before he even wrote the first line. Question 7: a design for measuring the viscosity of a liquid using only a marble, a graduated cylinder, and a stopwatch. No laser this time, but the same principle: use what you have, think from first principles. He scribbled an answer: Drag does work against
