Physics AS Level AQA
Acceleration ANS:change in V per unit t
Accurate ANS:Measurement obtained using calibrated instruments correctly
Alpha radiation ANS:Particle consisting of 2 P's and 2 N's
Amplitude ANS:Max displacement of oscillating particle from equilibrium position
Annihilation ANS:Particle and antiparticle meet, destroy eachother and emit radiation
Antibaryon ANS:Hadron w/ 3 quarks
Antimatter ANS:Antiparticles with same quantum values but opposite charge to corresponding particles
Antinode ANS:Fixed point on stationary wave where amplitude is maximum
Atomic number Z ANS:Number of P's in atom nucleus
Baryon ANS:Hadron w/ 3 quarks
Base units ANS:Units that define the SI system:
Kg
Amp
S
M
Beta radiation ANS:when B- or B+ particles are emitted following decay of a neutron-rich or proton-rich
nucleus
Breaking stress/Ultimate tensile stress ANS:Tensile stress needed to break a solid material
Brittle ANS:Snaps without bending or stretching when subject to stress
Centre of mass ANS:Point through which a single force on the body has no turning affect
Charge carriers ANS:Charged particles that move through substance when PD applied across it
Kirchoff's 1st Law ANS:Current passing through 2 or more components in series is the same through
each component
, At a junction the total current in = total current out
Kirchoff's 2 Law ANS:2 or more components in series - total PD across all the components is = to sum of
the PD's across each component
Sum of emf's around complete loop = sum of PD's around the loop
Coherent ANS:Constant phase difference and same frequency
Conservation rules ANS:Rule that:
Baryon no
Lepton no
Charge
Energy
Momentum
always conserved in interactions
When is strangeness conserved? ANS:Strong interactions
How are strange particles created? ANS:Strong interactions
How to strange particles decay? ANS:Weak interactions
Couple ANS:Pair of equal and opposite forces acting upon the same body but not along the same line
Critical angle ANS:The angle of incidence of a light ray must exceed this angle for total internal reflection
to occur
Critical temperature ANS:Temperature at or below which a superconducting material has zero resistivity
Cycle ANS:Interval for an oscillating particle from a certain displacement and velocity to the next time
the particle has identical displacement and velocity
de Broglie wavelength ANS:Wavelength of a matter particle
deexcitation ANS:process by which atom loses energy by photon emission as electron moves to lower
energy level - inner shell
