AQA A LEVEL PHYSICS PAPER 1 EXAM
SCRIPT 2026 COMPLETE QUESTIONS AND
CORRECT ANSWERS
◉superposition. Answer: when two or more waves occupy the same
region then the total displacement at any one point is the vector sum
of their individual displacements at that point
◉Coherence. Answer: Waves or wave sources, which have a constant
phase difference between them and a similar frequency
◉Electric current. Answer: This is the rate of flow of electric charge.
I = ∆Q/∆t. Unit: A
◉Potential difference. Answer: the energy converted from electrical
potential energy to some other form per coulomb of charge flowing
from between two points. Unit: volt (V) [= JC^-1].
◉emf. Answer: the energy converted from some other form (e.g.
chemical) to electrical potential energy per coulomb of charge
flowing through the source. Unit: volt (V) [= JC^-1].
, ◉Ohm's Law. Answer: the current through a conductor between two
points is directly proportional to the voltage across the two points
◉Electrical Resistance. Answer: The resistance of a conductor is the
p.d. (V) placed across it divided by the resulting current (I) through
it. R = V / IUnit: ohm (ΩΩΩΩ) [= VA^-1]
◉Resistivity. Answer: The resistance, R, of a metal wire of length L
and cross-sectional area A is given by R = ρ L / A, it is a constant for
the material of the wire Unit: ohm-metre (ΩΩΩΩm)
◉Conservation of Charge. Answer: Electric charge cannot be created
or destroyed, (though positive and negative charges can neutralize
each other). In a purely resistive circuit charge cannot pile up at a
point
◉Nucleon. Answer: Protons and neutrons have similar masses. They
are both classed as these, and are found in the centre of an atom
◉Atomic mass number. Answer: the number of protons and
neutrons in an atom
◉Atomic number. Answer: the number of protons in an atoms
nucleus
