AQA A level Physics Paper 1 Questions
And Answers Updated 2024/2025
1 eV = - correct answer1.6x10^-19 Joules
Absolute Refractive Index - correct answerThe ratio between the speed of light in a vacuum and the
speed of light in that material
Absorption - correct answerWhen some of the signal's energy is absorbed by the material that the fibre
is made from leading to a loss of amplitude of the signal
Alpha Decay - correct answerOccurs in nuclei of 82 protons or more that consists of an alpha particle
being emitted
Amplitude - correct answerThe maximum displacement of a wave from its equilibrium postion
Angular Speed - correct answerThe angle an object rotated through per second (omega = 2pi x
frequency)
Antinodes - correct answerPoints where the amplitude of vibration of the wave is maximum
Antiparticle - correct answerOpposite in charge to the particle but have the same rest mass and rest
energy
Atomic Number (Z) - correct answerThe number of protons in the nucleus of an atom
Breaking Stress - correct answerThe lowest stress that's big enough to break a material
Brittle Fracture - correct answerWhen a stress applied to a brittle material caused tiny crack at the
material's surface to get bigger until the material breaks completely
, Brittle Material - correct answerDoesn't deform plastically but snaps when the stress on it reaches a
certain point
Centre of Mass - correct answerThe point where an object's mass may be thought to be concentrated
Coherent - correct answerWaves that are the same wavelength and frequency and have a fixed phase
difference
Constructive Interference - correct answerWhen waves with displacements that are in the same
direction meet and have their displacements reinforce to create a larger displacement
Coulomb - correct answerThe amount of charge passing a point when a current of 1A flows for 1s
Couple - correct answerA pair of equal and opposite coplanar forces that act parallel to one anotherm
Critical Angle - correct answerThe angle of incidence for which the angle of refraction is exactly 90
degrees
Critical Damping - correct answerAmplitude of oscillation is reduced to zero in the shortest possible time
Critical Temperature - correct answerThe temperature below which a material will have zero resistance
and will become a superconductor
Current - correct answerRate of flow of charge
Density - correct answerThe ratio of the mass of a substance to its volume
Destructive Interference - correct answerWhen waves with displacements that are in the opposite
direction meet and have their displacements cancel out
