AQA A Level PHYSICS PAPER 2
May 2024 Exam Questions and
Answers
Gravitational Field - Answer>> A region in which an object that
has mass experiences a force
Field Lines - Answer>> Arrows which indicate the direction and
relative strength of a field. Arrows show the way in which a rest
mass would experience the force of attraction.
Equipotentials - Answer>> Lines drawn to indicate points of
equal potential. Cross field lines at 90 degrees
Newton's Law of Gravitation - Answer>> Every particle in the
universe attracts every other particle with a force that is directly
proportional to the product of their masses and inversely
proportional to the square of the distance between their centre's
F ~~ Mm/r^2
Gravitational field strength - Answer>> The force acting on a
body per unit mass
Gravitational Potential Energy - Answer>> Potential energy is
the work done in moving an object with mass from Infinity to that
point in the field
E=-gMm/r for radial field E=mg•dh (Scalar)
Absolute Gravitational potential - Answer>> The absolute
gravitational potential at a point is the work done per unit mass in
moving a body from Infinity to that point in the gravitational field
V=-Gm/r (scalar)

Orbital time period - Answer>> GMT^2 =4pi^2 •r^3 therefore T^2 prop R^ orbital velocity - Answer>> (GM/r)^1/ escape velocity - Answer>> (2GM/r)^1/ Satellites in geosynchronous orbit - Answer>> T=24hrs Orbital Radius roughly 36,000km Remember the subtle difference between geosynchronous and geostationary, Which stay above the same point on Earth. Satellites in a non-geosynchronous/polar orbit - Answer>> Different, usually smaller T than earth. Activity - Answer>> Number of emissions per second measured in Bq Alternating Current (AC) - Answer>> A flow of electric charge that continuously changes its direction and magnitude Avogadro's Law - Answer>> equal volumes of gases at the same temperature and pressure contain equal numbers of molecules Boltzmann's constant - Answer>> a physical constant relating the average kinetic energy of particles in a gas with the temperature of the gas; it is the gas constant R divided by Avogadro's number (1.38x10^-23 J K^-1) Boyle's Law - Answer>> P1V1=P2V

Faraday's Law - Answer>> When there is relative movement between a conductor and a magnetic field the EMF induced in the conductor is equal to the rate of change of magnetic flux linkage 1st law of thermodynamics - Answer>> Q = dU + w Q=Heat energy supplied dU=Change In interval energy W=Work done by system in surroundings Flux - Answer>> Total magnetic field passing through a particular area Magnetic flux = flux density x Area Flux linkage - Answer>> Within a current carrying coil, the sum of the magnetic flux due to each loop of the coil Heat capacity - Answer>> The energy required to raise the temperature of an 1kg object by 1K in J per C Intensity - Answer>> The power of the wave transmitted through a unit area perpendicular to the direction of travel of the wave; unit watts per square metre Internal Energy - Answer>> The energy of a substance due to the sum of the Ek and Potential energy of all it's constituent particles Latent Heat - Answer>> The energy needed for a substance to change state. No change in temperature. Lenz's Law - Answer>> The direction of an induced current is such that it'll oppose the change of magnetic flux that caused it.

Flux density - Answer>> A measure of the strength of a magnetic field. The flux density is equal to the magnitude of the force on a unit length of current carrying wire per unit current; unit Tesla. Magnetic flux linkage - Answer>> The total magnetic flux linkage through a coil of area A and number of turns N Moderator - Answer>> Material used in a nuclear reactor to slow down neutrons to thermal speeds via a collision. E.g graphite or water. Motor effect - Answer>> A wire carrying a current in a magnetic field experiences a force this is known as the motor effect Natural frequency - Answer>> The frequency at which a vibrating object undergoes free vibrations, for example the frequency at which a tuning fork will oscillate when struck Permittivity - Answer>> The ratio of the electric displacement in the material to the intensity of the electric field producing it. permittivity of free space - Answer>> The permittivity of a medium is a measure of the material's ability to resist the formation electric field within it. Using a dielectric with a permittivity greater than that of free space (a vacuum) increases the capacitance of a capacitor Resonance - Answer>> Large amplitude vibrations caused when the driving frequency matches the natural frequency of a system Search coil - Answer>> A flat coil of insulated wire with a large number of turns. When connected to an oscilloscope the search

Work done - Answer>> The product of the force and the distance moved Thank you for your purchase! Need academic assistance?
