AQA A LEVEL PHYSICS PAPER 1 NEWEST UPDATE
2025/2026 WITH ACTUAL QUESTIONS AND CORRECT
VERIFIED ANSWERS/ WELL ANALYSED, ALREADY
GRADED A+ (100%GUARANTEED PASS! )
Current - CORRECT ANSWER-Rate of flow of charge
Coulomb - CORRECT ANSWER-The amount of charge passing a point when a
current of 1A flows for 1s
Potential difference - CORRECT ANSWER-The work done per unit charge in
moving a small point positive charge between two points
Threshold Voltage for a Diode - CORRECT ANSWER-The voltage at which a
current will begin to flow at, assumed to be +0.6V if not stated
Reverse Bias - CORRECT ANSWER-When very little currency can flow in the
reverse direction of a diode
,Variable Resistor - CORRECT ANSWER-Can be used to change the current
through a circuit can also be called a rheostat
NTC Thermistor - CORRECT ANSWER-(A type of semiconductor) that has
decreasing resistance when its temperature increases - negative temperature
coefficient
Transitional Temperature - CORRECT ANSWER-The critical temperature at
and below which a superconductor has zero resistivity
Semiconductor - CORRECT ANSWER-A group of materials which conduct
electricity (not as well as metals), when their temperature rises they can
release more charge carriers and their resistance decreases
Resistance - CORRECT ANSWER-The ratio of a components potential
difference to its current
Volt - CORRECT ANSWER-The potential difference across a component when
1 joule of energy is used to move a coulomb of charge through a component
Ohm's Law - CORRECT ANSWER-Provided that the physical conditions remain
the same, the current through an ohmic conductor is directly proportional to
the potential difference across it
Stopping Potential - CORRECT ANSWER-The work done by the potential
difference in stopping the fastest moving electrons
, Electron Volt - CORRECT ANSWER-The kinetic energy that an electron has
after being accelerated from rest through a potential difference of 1 volt
1 eV = - CORRECT ANSWER-1.6x10^-19 Joules
Ground State - CORRECT ANSWER-The lowest energy level that an electron
can occupy in an atom (n=1)
Excitation - CORRECT ANSWER-When an electron gains the exact amount of
energy needed to move up to a higher energy level in an atom
Ionisation - CORRECT ANSWER-The process when an electron gains enough
energy from a photon to leave the ground state of the atom that it's in
Ionisation Energy - CORRECT ANSWER-The amount of energy needed to
remove an electron from the ground state of an atom
Radian - CORRECT ANSWER-The angle that is equal to the arc length divided
by the radius of the circle 2pi radians = 360 degrees
Angular Speed - CORRECT ANSWER-The angle an object rotated through per
second (omega = 2pi x frequency)
Frequency - CORRECT ANSWER-The number of complete revolutions per
second
