Energy is transferred between stores - CORRECT ANSWERS Thermal, kinetic, gravitational
potential, elastic potential, chemical, magnetic, electrostatic, nuclear
Energy is transferred... - CORRECT ANSWERS 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 ANSWERS 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 ANSWERS 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 ANSWERS
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 ANSWERS 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 ANSWERS 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 ANSWERS 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 ANSWERS Energy can be transferred but can
never be created of destroyed
Dissipated energy - CORRECT ANSWERS energy used up in a system, typically lost due to
work done by friction, 'wasted energy'
Phone energy - CORRECT ANSWERS 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 ANSWERS 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 ANSWERS The rate at which work is done (watts). P(w) = E(j) / t(s)
Powerful machine - CORRECT ANSWERS One which transfers a lot of energy in a short space
of time

Conduction occurs mainly in solids - CORRECT ANSWERS Conduction is the process where
vibrating particles transfer energy to neighbouring particles.
Long definition of conduction - CORRECT ANSWERS 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 ANSWERS the Mrs sure of the rate at which thermal energy
can travel through a material
Convection occurs only in liquids and gases - CORRECT ANSWERS Convection is where
energetic particles move away from hotter to cooler regions
Convection longer definition - CORRECT ANSWERS Unlike in solids, the particles in liquids
and gases are able to move. When you heat a region of a gas/liquid, the particles move
faster and the space between particles increases. This causes the density of the region to
decrease. Because they can flow, the warmer and less dense region will rise above denser
cooler regions. If there is a constant heat source, a convection current will be made
Radiators - convection currents - CORRECT ANSWERS Energy is transferred from the radiator
to nearby air particles by conduction. The air by the radiator becomes warmer and less
dense. This warm air rises and is replaced by cooler air. At the same time, the previously
heated air transfers energy to the surrounding and cools, becomes denser, and sinks. This
cycle repeats and causes a flow of air to circulate around the room
