AQA GCSE COMBINED PHYSICS TEST
QUESTIONS WITH 100% CORRECT
ANSWERS
Absorption - answer When a wave transfers energy to the energy stores of a material.
Acceleration - answer A measure of how quickly velocity is changing.
Accurate result - answer A result that is very close to the true answer.
Activity (radioactive) - answer The number of nuclei of a sample that decay per second.
Air resistance - answer The frictional force caused by air on a moving object.
Alpha decay - answer A type of radioactive decay in which an alpha particle is given out from a
decaying nucleus.
Alpha particle - answer A positively-charged particle made up of two protons and two neutrons
(a helium nucleus).
Alpha particle scattering experiment - answer An experiment in which alpha particles were fired
at gold foil to see if they were deflected. It led to the plum pudding model being abandoned in
favour of the nuclear model of the atom.
Alternating current (AC) - answer Current that is constantly changing direction.
Ammeter - answer A component used to measure the current through a component. It is always
connected in series with the component.
,Amplitude - answer The maximum displacement of a point on a wave from its rest position.
Angle of incidence - answer The angle the incident ray of a wave makes with the normal at a
boundary.
Angle of refraction - answer The angle a refracted ray makes with the normal when a wave
refracts at a boundary.
Anomalous result - answer A result that doesn't seem to fit with the rest of the data.
Atmosphere - answer A relatively thin layer of air that surround the Earth.
Atom - answer Particles that make up matter.
Atomic number - answer The number of protons in the nucleus of an atom.
Beta decay - answer A type of radioactive decay in which a beta particle is given out from a
decaying nucleus.
Beta particle - answer A high-speed electron emitted in beta decay.
Bias - answer Unfairness in the way data is presented, possibly because the presenter is trying
to make a particular point (sometimes without knowing they're doing it).
Bio-fuel - answer A renewable energy resource made from plant products or animal dung.
Braking distance - answer The braking distance is the distance a vehicle travels after the brakes
are applied until it comes to a complete stop, as a result of the braking force.
, Calibrate - answer Measure something with a known quantity to see if the instrument being
used to measure that quantity gives the correct value.
Carbon neutral fuel - answer A fuel that absorbs as much CO2 from the atmosphere (when it's
produced) as it releases when it's burned.
Categoric data - answer Data that comes in distinct categories, e.g. blood type (A+ B- etc.)
Closed system - answer A system where neither matter nor energy can enter or leave. The net
change in total energy in a closed system is always zero.
Conduction - answer A method of energy transfer by heating where vibrating particles transfer
energy through a material by colliding with neighbouring particles and transferring energy
between their kinetic stores.
Conductor (electrical) - answer A material in which electrical charges can easily move.
Conservation of energy principle - answer Energy can be transferred usefully from one energy
store to another, stored or dissipated - but it can never be created or destroyed.
Conservation of momentum - answer In a closed system, the total momentum before an event
is the same as the total momentum after the event.
Contamination (radioactive) - answer The presence of unwanted radioactive atoms on or inside
an object.
Continuous data - answer Numerical data that can have any value within a range (e.g. length).
