Physics 7408/3A June 2018

The AQA Paper 3 Physics exam (June 2018) Section A focuses on various practical experiments and theoretical concepts in physics. It includes the measurement of forces in a magnetic field, the determination of the mass of a ruler, and the calculation of the magnetic flux density. The section also tests the understanding of electric fields, the behavior of conducting wires in magnetic fields, and experimental procedures for measuring current and voltage. The paper involves graph interpretation, such as determining the gradient and intercept of a graph, and applying Charles’s Law to estimate absolute zero. Experimental setups for measuring force between wires and analyzing air volume in a flask are also featured.
