The AQA A-level Physics Paper 1 (November 2021) evaluates core physics concepts including cosmic ray interactions, particle decay, and strangeness conservation. Topics include determination of specific charge, properties of electromagnetic waves, double-slit interference, and projectile motion. Optical fibre mechanics, centripetal forces, and spacecraft design are explored. The paper also covers photoelectric effect, Young modulus, electrical circuits, and SHM energy calculations. Practical problem-solving integrates theoretical physics principles with experimental applications. Keywords: AQA Physics, cosmic rays, microwaves, projectile motion, optical fibre, Young modulus, photoelectric effect, simple harmonic motion.
