Physics 7408/3A June 2023

The AQA A-level Physics Paper 3A (June 2023) focuses on experimental and data analysis skills, including stroboscopic motion studies, filament lamp behavior, and magnetic field measurements. Key areas involve graphical techniques to determine gravitational acceleration, horizontal and vertical motion analysis, and coil-induced magnetic flux density. Questions assess experimental design, data logging advantages, and calculations involving current, resistance, and power dissipation. Practical applications emphasize precision in measurements and the use of mathematical models to derive physical constants. Keywords: AQA Physics, experimental physics, stroboscope, filament lamp, magnetic flux, data logging, motion analysis.
