A-LEVEL PHYSICS PAPER 2 EXAM-STYLE
PRACTICE SET 2026
◉ Electromagnetic induction. Answer: Phenomenon in which a
changing magnetic field, relative to a wire, will produce an emf.
◉ Fleming's right hand rule. Answer: Also known as the dynamo
rule. Works out directions involved in electromagnetic induction.
◉ Solenoid. Answer: Electrical coil.
◉ Lenz's law. Answer: "The direction of the induced current is
always such as to oppose the change that caused the current".
◉ Magnetic flux. Answer: Product of the magnetic flux density and
the area.
◉ Magnetic flux linkage. Answer: Product of the magnetic flux and
the number of turns of the coil.
◉ Faraday's law. Answer: "The induced emf in a circuit is equal to
the rate of change of flux linkage through the circuit".
,◉ Alternator. Answer: Generator of AC.
◉ Back emf. Answer: An emf generated in a motor that works
against the current that is powering the motor.
◉ Step-up. Answer: Transformer that raises the voltage and lowers
the current (answer is hyphenated!)
◉ Step-down. Answer: Transformer that lowers the voltage and
raises the current (answer is hyphenated!)
◉ National Grid. Answer: Network of transformers and cables that
transmits power across the country.
◉ Pressure. Answer: The force per unit area exerted normally (at 90
degrees) on a surface.
◉ Boyle's law. Answer: For a fixed mass of gas at constant
temperature, pV = constant.
◉ Charles' law. Answer: For a fixed mass of gas at constant pressure,
V/T = constant.
, ◉ Pressure law. Answer: For a fixed mass of gas at constant volume,
p/T = constant.
◉ Brownian motion. Answer: The random and unpredictable motion
of a particle (like a smoke particle) caused by molecules of the
surrounding material colliding with it at random.
◉ Avagadro constant. Answer: Number of particles in a mole of a
substance. 6.02x10^23.
◉ Mole. Answer: Amount of substance with 6.02x10^23 particles in
it.
◉ Molarity. Answer: Number of moles in a substance. Measured in
mol.
◉ Molar mass. Answer: Mass of 1 mol of a substance.
◉ Ideal gas. Answer: Gas that obeys Boyle's law.
◉ Molar gas constant. Answer: Constant with symbol R.
