AQA A Level Physics Paper 1 Exam with Questions and Answers – 100% Solved
1 eV = - ✔✔✔-1.6x10^-19 Joules
Absolute Refractive Index - ✔✔✔-The ratio between the speed of light in a vacuum and the
speed of light in that material
Absorption - ✔✔✔-When 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 - ✔✔✔-Occurs in nuclei of 82 protons or more that consists of an alpha particle
being emitted
Amplitude - ✔✔✔-The maximum displacement of a wave from its equilibrium postion
Angular Speed - ✔✔✔-The angle an object rotated through per second (omega = 2pi x
frequency)
Antinodes - ✔✔✔-Points where the amplitude of vibration of the wave is maximum
Antiparticle - ✔✔✔-Opposite in charge to the particle but have the same rest mass and rest
energy
Atomic Number (Z) - ✔✔✔-The number of protons in the nucleus of an atom
Breaking Stress - ✔✔✔-The lowest stress that's big enough to break a material
Brittle Fracture - ✔✔✔-When 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 - ✔✔✔-Doesn't deform plastically but snaps when the stress on it reaches a
certain point
Centre of Mass - ✔✔✔-The point where an object's mass may be thought to be concentrated
Coherent - ✔✔✔-Waves that are the same wavelength and frequency and have a fixed phase
difference
Constructive Interference - ✔✔✔-When waves with displacements that are in the same
direction meet and have their displacements reinforce to create a larger displacement
Coulomb - ✔✔✔-The amount of charge passing a point when a current of 1A flows for 1s
Couple - ✔✔✔-A pair of equal and opposite coplanar forces that act parallel to one anotherm
Critical Angle - ✔✔✔-The angle of incidence for which the angle of refraction is exactly 90
degrees
Critical Damping - ✔✔✔-Amplitude of oscillation is reduced to zero in the shortest possible
time
Critical Temperature - ✔✔✔-The temperature below which a material will have zero resistance
and will become a superconductor
Current - ✔✔✔-Rate of flow of charge
Density - ✔✔✔-The ratio of the mass of a substance to its volume
