Acceleration - Answer The rate of change of velocity
Accurate result - Answer A result that is close to the true answer
Apha decay - Answer A type of decay in which an unstable nucleus of an atom emits an alpha particle
Alternating current - Answer A current that changes with time in a regular cycle
Ammeter - Answer A component used to measure the current flowing through a circuit
Amplitude - Answer The maximum displacement of a wave
Angle of incidence - Answer The angle that incoming light makes to the normal or a boundry
Angle of refraction - Answer The angle that incoming light makes to the normal of a boundary
Annihilation - Answer The 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 - Answer A result that doesn't fit in with the pattern of the other results in a set of
data
Antimatter - Answer The name given to all antiparticles
Antineutrino - Answer The antiparticle of a neutrino
, Antiparticle - Answer A particle with the same rest mass and energy as its corresponding particle but
equal and opposite charge

particle (an electron) and an antineutrino
Breaking stress - Answer The lowest stress that is big enough to break a material
Brittle - Answer A brittle material doesn't deform plastically but snaps when the stress on it reaches a
certain point `
Brittle fracture - Answer When a stress app;lied to a brittle material causes tiny cracks at the materials
surface to get bigger until the material breaks completely
Categoric data - Answer Data that can be sorted into categories
Center of mass - Answer The point which you can consider all of an object's weight to act through
Circuit symbol - Answer A pictorial representation of an electrical component
Coherent - Answer Sources that have the same wavelength and frequency and a fixed phase difference
between them are coherent
