AS level Physics - AQA A
exam questions &
answers
Acceleration - ANSWERSThe rate of change of velocity
Accurate result - ANSWERSA result that is close to the true answer
Apha decay - ANSWERSA type of decay in which an unstable nucleus of an atom emits an alpha
particle
Alternating current - ANSWERSA current that changes with time in a regular cycle
Ammeter - ANSWERSA component used to measure the current flowing through a circuit
Amplitude - ANSWERSThe maximum displacement of a wave
Angle of incidence - ANSWERSThe angle that incoming light makes to the normal or a boundry
Angle of refraction - ANSWERSThe angle that incoming light makes to the normal of a boundary
Annihilation - ANSWERSThe process by which a particle and its antiparticle meet and their mass
gets converted to energy in the form of a pair of gamma ray photons
Anomalous result - ANSWERSA result that doesn't fit in with the pattern of the other results in a
set of data
, Antimatter - ANSWERSThe name given to all antiparticles
Antineutrino - ANSWERSThe antiparticle of a neutrino
Antiparticle - ANSWERSA particle with the same rest mass and energy as its corresponding
particle but equal and opposite charge
Atom - ANSWERSA particle made up of protons and neutrons in a central nucleus and electrons
orbiting the nucleus
Atomic number - ANSWERSThe number of protons in an atom of an element
Baryon - ANSWERSA type of hardon made up of three quarks
Baryon number - ANSWERSThe number of baryons in a particle
Beta-minus decay - ANSWERSA type of decay in which an unstable nucleus of an atom emits a
beta-minus particle (an electron) and an antineutrino
Breaking stress - ANSWERSThe lowest stress that is big enough to break a material
Brittle - ANSWERSA brittle material doesn't deform plastically but snaps when the stress on it
reaches a certain point `
Brittle fracture - ANSWERSWhen a stress app;lied to a brittle material causes tiny cracks at the
materials surface to get bigger until the material breaks completely
