Energy Flashcards
Potential energy
This is stored energy that
is just waiting to do work such as a coiled
spring or elastic band
Kinetic energy
The energy that moving
things have ie, a windmill turning or a car
moving
Heat energy
Heat is energy because it can
cause things to move
Hot air causes a hot air balloon to rise, heat
in a steam engine moves trains!
Light energy
Light can move things in a
Crookes Radiometer or in a solar powered
calculator
Sound energy
If you put your head near a
loudspeaker you can feel that air being
moved by sound energy
Electrical energy
This energy can make
things like extractor fans move
Chemical energy
This is the type of energy
stored in fuels such as coal and oil, it is also
stored in the food we eat and in batteries
Nuclear energy
this energy is stored in the
nucleus of atoms
Circuits
A circuit is made up of a battery, some wires
and different types of equipment and can be
used to observe energy conversions
Solar energy
solar panels on buildings use
the sun’s energy to heat water
Hydro electric energy
Dams hold back
water and then let it drop onto a wheel to
turn a generator turbine to make electricicty
Wind energy
Wind can turn windmills which
generate electricity
Wave energy
The movement of large floats
by the energy in waves could be used to
generate electricity
Biomass energy
Some plants produce oils
others can produce fuels such as alcohol and
methane gas
Geothermal energy
The temperature under
the Earth’s surface increases with depth this
heat can be used to heat water in some
places
