Abstract:

The AQA A-level Physics Paper 3A (June 2022) focuses on experimental physics and practical applications, covering Young’s modulus, speed of sound in steel, conductive putty resistance, and Boyle’s law. Key tasks include graphical analysis of data, parallax error reduction techniques, and uncertainty estimation in measurements. Experimental setups explore wave reflections in rods, deflection in steel strips, and resistivity determination using geometric and resistance data. Additional emphasis is placed on pressure-volume relationships and validation of gas laws. Keywords: AQA Physics, experimental physics, Young’s modulus, speed of sound, resistivity, Boyle’s law, uncertainty analysis, graphical methods.
