AQA GCSE Combined Science Physics -
Paper 1 Exam Questions and Answers
Graded A+
Energy is transferred between stores - Correct answer-Thermal, kinetic,
gravitational potential, elastic potential, chemical, magnetic, electrostatic, nuclear
Energy is transferred... - Correct answer-Mechanically (by a force doing work),
electrically (work done by moving charges), by heating or by radiation (like light
or sound)
When a system changes, energy is transferred - Correct answer-It can be
transferred into or away from the system, between objects in the system or between
different types of energy stores. Closed systems are where neither matter nor
energy can enter or leave. The net change in the total energy of a closed system is
always 0
kinetic energy - Correct answer-energy of motion - the greater an object's mass and
the faster it is going, the more energy there will be in its kinetic energy store. Ek (j)
= 1/2m(kg)v(m/s) squared

,Raised objects store energy in gravitational potential energy stores - Correct
answer-lifting an object in a gravitational field requires work, causing an energy
transfer to the the GPE store of the object. Ep(j) = m(kg)g(n/kg)h(m)
Falling objects transfer energy - Correct answer-Falling objects transfer energy
from its GPE store to its kinetic energy store. When there's no air resistance,
energy lost from the GPE store = energy gained in the kinetic energy store
Stretching transfers energy to elastic potential energy stores - Correct answer-As
long as the limit of proportionality has not been exceeded, Ee (j) = 1/2 k (N/m) e
(m) squared
specific heat capacity - Correct answer-the energy required to raise the temperature
of one gram of a substance by one degree Celsius. E (j) = m(kg) c(j/kgdegree)
theta (degrees Celsius)
Conservation of energy principle - Correct answer-Energy can be transferred but
can never be created of destroyed
Dissipated energy - Correct answer-energy used up in a system, typically lost due
to work done by friction, 'wasted energy'

, Phone energy - Correct answer-When you use the phone, energy is usefully
transferred from the chemical energy store of the battery in the phone, but some of
this energy is dissipated to thermal energy
Closed system energy transfer - Correct answer-A cold spoon is dropped into hot
soup in an insulated flask, which is then sealed. Energy is transferred from the
thermal energy store of the soup to the useless thermal energy of the spoon
Power - Correct answer-The rate at which work is done (watts). P(w) = E(j) / t(s)
Powerful machine - Correct answer-One which transfers a lot of energy in a short
space of time
Conduction occurs mainly in solids - Correct answer-Conduction is the process
where vibrating particles transfer energy to neighbouring particles.
Long definition of conduction - Correct answer-Energy transferred to an object by
heating is transferred to the thermal store, which is shared across the kinetic store
of the particles. The particles' collisions cause energy to be transferred between
particles kinetic energy stores.
thermal conductivity - Correct answer-the Mrs sure of the rate at which thermal
energy can travel through a material
