Pack | Grade A+
• sound energy store . CORRECT ANSWER: Energy caused by an object's vibrations
• thermal energy store . CORRECT ANSWER: The total energy of motion in the
particles of a substance
• chemical energy store . CORRECT ANSWER: A form of potential energy that is
stored in chemical bonds between atoms.
• nuclear energy store . CORRECT ANSWER: the potential energy stored in the
nucleus of an atom
• electrical energy store . CORRECT ANSWER: Energy caused by the movement of
electrons.
• light energy store . CORRECT ANSWER: Energy in the form of moving waves of light
• kinetic energy store . CORRECT ANSWER: energy of motion
• gravitational potential energy store . CORRECT ANSWER: potential energy that
depends on the height of an object
• elastic potential energy store . CORRECT ANSWER: the energy of stretched or
compressed objects
• conservation of energy . CORRECT ANSWER: law that says energy cannot be
created or destroyed, but can change forms
• uses of friction . CORRECT ANSWER: - rubbing hands for warmth
- break pads on bikes
• Efficiency = . CORRECT ANSWER: Useful Energy Output / Total Energy Input
• Increase efficiency . CORRECT ANSWER: - add lubricant
- reduce friction
• internal energy . CORRECT ANSWER: the sum of the kinetic and potential energies
of all particles in the system
• Conduction . CORRECT ANSWER: The direct transfer of heat from one substance to
another substance that it is touching.
, • Convection . CORRECT ANSWER: The transfer of thermal energy by the circulation
or movement of a liquid or gas
• convection current . CORRECT ANSWER: a current caused by the rising of heated
fluid and sinking of cooled fluid
• Insulator . CORRECT ANSWER: A material that does not allow heat or electrons to
move through it easily.
• Infra red radiation . CORRECT ANSWER: Electromagnetic waves of heat energy.
• Radiation . CORRECT ANSWER: Energy that is radiated or transmitted in the form of
rays or waves or particles.
• greenhouse effect . CORRECT ANSWER: CO2 and other greenhouse gases in the
atmosphere absorb long wavelength radiation radiated from the Earth's surface and
prevent it escaping.
• black . CORRECT ANSWER: good absorber of radiation
• white . CORRECT ANSWER: poor absorber of radiation
• specific heat capacity . CORRECT ANSWER: the energy required to raise the
temperature of one gram of a substance by one degree Celsius
• Reduce heat loss from homes . CORRECT ANSWER: - loft insulation (fibre glass is a
good insulator)
- cavity wall insulation (foam prevents convection currents)
- aluminum foil behind radiator (reflects radiation)
- double glazing (vacuum slows conduction and radiation)
• energy transfer . CORRECT ANSWER: power x time
• non-renewable energy . CORRECT ANSWER: A natural resource such as coal, gas,
or oil that, once consumed, cannot be replaced.
• renewable energy . CORRECT ANSWER: A resource that has a theoretically
unlimited supply and is not depleted when used by humans.
solar, wind, geothermal, hydropower, tidal, wave, nuclear, biofuel
dis: unreliable (except hydroelectric and geothermal)
• nuclear power . CORRECT ANSWER: energy from splitting Uranium atoms.
dis: nuclear waste, expensive
